Some coilover kits come with top mounts, while others require you to reuse your factory mounts or buy compatible mounts separately. The answer depends on the kit, vehicle, and suspension design.
If you are upgrading your car’s suspension in the United States, check the contents of the coilover kit before you order it. A complete kit may include upper mounts, springs, dampers, and adjustment hardware. A different kit may include only the coilover units and require you to transfer parts from your original suspension.
Top mounts connect the upper end of a suspension strut or coilover to the vehicle body. They may also contain rubber insulation, a bearing, or a plate that helps the suspension move as the wheels turn. The exact design depends on the vehicle and whether the suspension uses a strut or another layout.
The key is to distinguish a coilover that includes a new top mount from one that is merely compatible with your factory mount. Read the exact product listing and installation manual, then confirm the front and rear requirements for your vehicle. This simple check can help prevent missing parts, extra costs, and installation delays.
No, coilover kits do not all come with top mounts. Some manufacturers supply complete assemblies with new upper mounts, while others supply the spring and damper units without the vehicle-specific mounting parts. Both designs are common, so the product name alone does not tell you what is included.
A listing that says a kit is vehicle-specific does not automatically mean it includes every part needed for installation. It may be designed to work with the factory upper mounts. Other kits may require separate mounting plates or additional hardware, depending on the vehicle.
For example, a kit for a sport compact car may include front camber plates but expect the owner to reuse the original rear upper mounts. Another kit for a different model may include all four upper mounting assemblies. These are examples of possible configurations, not specifications for a particular product.
Always check the parts list for the exact model and kit version. If the listing is unclear, ask the seller or manufacturer whether the front and rear top mounts are included and whether any original parts must be transferred.

Complete coilover kits
These may include coilovers, upper mounts, adjustment tools, and the hardware specified by the manufacturer. Confirm the actual contents because the term complete can vary.
Coilovers that reuse factory mounts
These are designed to accept the original upper mounts when those parts are compatible and in suitable condition.
Coilovers with optional mounts
Some systems offer different upper mounts or camber plates as separate options. The correct choice depends on the vehicle and intended use.
What Does Included Top Mount Mean?
An included top mount is a new upper mounting component supplied with the kit. It may be a rubber-insulated mount, a metal plate, a bearing assembly, or a more complex adjustable unit. The term does not always mean that every bearing, spacer, nut, or related fastener is included.
Check whether the mount is already assembled on the coilover or supplied as a separate part. Also confirm whether the kit includes any required vehicle-specific hardware. A new mount that looks similar to the original may still have a different bolt pattern or bearing design.
Check the parts diagram
Look for named upper mounts, top plates, bearings, spacers, and required fasteners.
Check the installation manual
Look for instructions to transfer the factory mount or install the supplied replacement.
What Is a Coilover Top Mount?
A coilover top mount is the component that connects the upper end of a coilover or strut assembly to the vehicle. It helps hold the suspension in the correct position and transfers suspension forces into the vehicle’s mounting structure.
Depending on the design, a top mount can also reduce road noise, limit vibration, and allow the upper end of the strut to move as the suspension works. On a front suspension that turns with the steering, a bearing may allow the assembly to rotate smoothly.
Not every vehicle uses the same arrangement. Some independent rear suspensions use a separate spring and shock, so the spring’s upper seat and the shock’s upper mount are different parts. A coilover conversion may change this arrangement, but only when the kit is designed for that application.

Structural support
The mount helps secure the suspension assembly to the vehicle body or chassis.
Vibration control
Rubber or other isolating materials can reduce the transfer of road noise and vibration into the cabin.
Steering movement
Some front mounts contain bearings that allow the suspension assembly to rotate with steering input.
Adjustment
Certain performance mounts allow changes to camber or other specified suspension settings.
Top Mounts and Top Hats: Are They the Same?
The terms top mount and top hat are often used for the upper part of a coilover assembly. However, sellers and manufacturers may use them to describe different pieces. A top hat may refer to the upper spring seat or mounting plate, while a top mount may refer to the full assembly that attaches to the body.
Do not rely on the name alone when comparing parts. Check the diagram and part numbers to see whether the item includes a bearing, rubber insulator, spring seat, or only a metal plate.
Top mount
Often describes the upper mounting assembly that attaches the suspension to the vehicle.
Top hat
May describe an upper plate or spring seat, depending on the manufacturer and application.
Types of Coilover Top Mounts
The type of top mount matters as much as whether one comes in the box. A rubber mount often favors comfort and noise control, while a rigid performance mount can provide a more direct connection. Adjustable plates may allow alignment changes, but they can also transmit more road noise into the cabin.
Choose a mount that matches the coilover design, vehicle, and intended use. A part made for track use may not offer the comfort or isolation that a daily driver needs. Likewise, a standard replacement mount may not provide the adjustment required for a particular suspension setup.

Rubber top mounts
These use rubber or similar isolating material to reduce vibration and noise. They can be suitable for everyday driving when specified for the vehicle.
Pillowball or spherical mounts
These use a spherical bearing to allow controlled movement with less rubber compliance. They can improve steering precision in suitable applications but may increase noise and vibration.
Camber plates
These allow certain suspension mounting points to move so camber can be adjusted within the system’s design limits. They are not included in every coilover kit.
Fixed metal mounts
These provide a set mounting position and may be part of a performance-focused assembly. Their suitability depends on the intended vehicle and suspension design.
Which Top Mount Is Best for Street Driving?
For a daily-driven car, a compatible rubber-isolated mount is often a sensible option when the suspension manufacturer supports it. It can help reduce harshness and cabin noise on rough roads. The coilover spring rate, damper tuning, tire choice, and vehicle design also affect ride comfort.
A spherical mount may suit a car that sees frequent track use, but it is not automatically better for every driver. Some designs allow more mechanical noise to enter the cabin, and some require inspection or service. Follow the manufacturer’s guidance rather than selecting a mount based only on its material.
For everyday use
Prioritize compatible mounts, noise isolation, correct steering movement, and the suspension manufacturer’s street-use guidance.
For performance use
Consider alignment adjustment and bearing design, while checking noise, maintenance, and intended-use limits.
Do Coilovers Include Front and Rear Top Mounts?
Some kits include front and rear mounts, but others include only selected mounts or require factory parts to be reused. The answer can differ between the front and rear of the same car because the suspension layouts may not match.
Front strut assemblies often attach to the body through an upper mount. Depending on the vehicle, the mount may contain a steering bearing or support a camber-adjustment system. Rear suspension designs vary more widely, and some use separate upper mounts for the shock and spring.
Do not assume that a four-corner coilover kit includes four identical mounts. The parts may be different in shape, function, and attachment method. Review the installation diagrams for each axle before deciding which additional parts to buy.

Front mounts
Check whether the kit includes the required upper mounts, steering bearings, camber plates, and specified hardware.
Rear mounts
Confirm the rear suspension layout and whether the kit uses separate spring and shock mounts or a combined coilover assembly.
Vehicle-specific hardware
Check for any required spacers, sleeves, bolts, or adapters listed in the installation instructions.
Why the Same Kit Can Have Different Mounting Requirements
Suspension parts vary by model, trim, production date, and sometimes factory performance package. A kit for one version of a car may not fit another version, even when the vehicles share a model name.
Aftermarket changes can also affect compatibility. A vehicle with modified suspension geometry or nonstandard mounting points may need a different approved configuration. Confirm the exact year, make, model, trim, and any relevant factory options before ordering.
Verify the exact application
Use the manufacturer’s fitment list and confirm any exclusions or special requirements.
Check both axles
Read the front and rear parts lists separately rather than assuming the same inclusion rules apply to all four corners.
Can You Reuse Factory Top Mounts With Coilovers?
Yes, you can reuse factory top mounts when the coilover manufacturer specifies that arrangement and the mounts are compatible and in good condition. Many suspension kits are designed around the original mounting hardware, so buying replacement mounts may not be necessary.
However, reuse is not suitable for every kit or every vehicle. Some coilovers require a dedicated upper mount, a different bearing, or a supplied adjustment plate. A factory mount that appears to fit may still have the wrong dimensions or interfere with the spring, damper, or steering movement.
Inspect reused mounts for cracks, torn rubber, corrosion, loose bearings, unusual movement, and other signs of wear. A worn mount can cause noise or poor suspension behavior even when the new coilovers are installed correctly. If the manufacturer calls for new mounts, follow that requirement.
Source: more-japan.com
Reuse them when approved
The installation manual must allow the original mounts, and the parts must match the new suspension.
Replace damaged mounts
Do not reinstall mounts with damaged rubber, worn bearings, cracked parts, or other defects that affect safe operation.
Check related hardware
Confirm that the required nuts, bolts, washers, and spacers are suitable for reuse or replacement under the manufacturer’s instructions.
Should You Replace Top Mounts When Installing New Coilovers?
Replacing the mounts during a coilover installation can make sense when the original parts are worn, noisy, damaged, or required to be replaced by the kit instructions. It can also avoid repeating suspension disassembly soon after the installation if an old mount is near the end of its useful life.
There is no universal rule that every new coilover installation requires new top mounts. If the factory mounts are serviceable and the manufacturer permits reuse, keeping them may be reasonable. Base the decision on the mount’s condition, compatibility, service guidance, and the cost of repeating the work.
If you are unsure whether a mount is worn, have a qualified technician inspect it before installation. Suspension mounts are structural components, and a poor fit or defective part can affect handling and steering.
Replacement is more likely to be needed
The mount is damaged, the bearing binds, the rubber is deteriorated, or the installation manual requires a new part.
Reuse may be acceptable
The manufacturer approves reuse, the mount is compatible, and inspection shows no relevant wear or damage.
How to Check Whether Your Coilovers Come With Top Mounts
The most reliable way to confirm whether coilovers include top mounts is to check the manufacturer’s parts list and installation manual for the exact kit. Product photographs can help, but a picture alone cannot confirm which components are included in the box.
Before ordering, identify the full part number and the vehicle application. Then check the front and rear contents, the required factory parts, and any optional upper mounting components. If the listing uses unclear terms, contact the seller with the exact part number and ask for written confirmation.
Source: m.media-amazon.com
Step 1: Confirm the exact kit
Match the part number to your vehicle’s year, make, model, trim, and suspension layout.
Step 2: Read the parts list
Look for top mounts, upper mounts, camber plates, bearings, spring seats, and any separate mounting hardware.
Step 3: Review the installation manual
Check whether the instructions show a new mount being installed or the factory mount being transferred.
Step 4: Check front and rear requirements
Verify each axle independently because the mounting components may differ.
Step 5: Ask about missing details
If the listing does not state whether mounts are included, request a clear answer before buying.
A Quick Parts Checklist Before You Buy
Use this checklist to compare a kit’s contents with what your vehicle needs. The exact list depends on the suspension design, so treat it as a guide rather than a universal parts requirement.
Coilover assemblies
Confirm that the required front and rear units are included.
Upper mounts
Check whether new mounts are supplied or factory mounts must be reused.
Bearings and adjustment plates
Confirm whether these are included, required, or optional for your application.
Installation hardware
Check which nuts, bolts, washers, sleeves, and spacers are supplied or must be replaced.
Instructions and torque values
Make sure you can access the instructions for the exact kit before installation.
What Happens If Coilovers Do Not Include Top Mounts?
If the kit does not include top mounts, you must follow the manufacturer’s instructions to determine which additional parts are needed. The solution may be to transfer compatible factory mounts, buy the specified upper mounts, or obtain a separate approved mounting assembly.
Do not assume that a missing mount means the kit is incomplete. Some kits are intentionally supplied without mounts because they are designed to reuse factory parts. However, if the parts list promises mounts and the package does not contain them, contact the seller before proceeding.
Never install a coilover with an improvised mount or an incompatible plate. The upper connection must fit the vehicle and the suspension assembly correctly. Incorrect mounting can lead to movement, noise, alignment problems, or component failure.

If factory mounts are required
Inspect the original parts, confirm compatibility, and transfer them only as directed by the installation manual.
If separate mounts are required
Buy the specified parts for the exact coilover kit and vehicle application.
If advertised parts are missing
Document the package contents and contact the seller or manufacturer before installation.
Can You Install Coilovers Without Top Mounts?
A coilover assembly must have the correct upper mounting arrangement specified for the vehicle. If the design requires a top mount and that part is missing, the installation is not ready to proceed.
Some designs use a factory mount or a separate upper connection rather than a new mount supplied in the box. That does not mean the mount can be omitted. Use the complete approved mounting system and do not drive the vehicle until the suspension is correctly assembled and inspected.
Stop if a required part is missing
Obtain the correct component before completing the installation or using the vehicle.
Avoid improvised substitutions
Do not modify mounting plates or substitute unrelated hardware without explicit manufacturer approval.
Do Top Mounts Affect Ride Quality and Handling?
Yes, top mounts can affect ride quality, steering response, and suspension noise, but the result depends on the mount design and the rest of the suspension. A rubber-isolated mount can reduce vibration, while a rigid mount can allow a more direct response at the cost of greater noise or harshness.
A mount also needs to work with the suspension’s intended movement. A damaged bearing can make steering less smooth, while a loose or worn mount can cause knocking sounds. These symptoms are not proof that the top mount is the cause, because other suspension parts can produce similar signs.
Adjustable camber plates can help set wheel alignment within their designed range. They do not automatically improve grip or handling in every situation. The correct alignment depends on the vehicle, tires, driving conditions, and intended use.

Noise and vibration
The mount’s material and condition can affect how much road noise reaches the cabin.
Steering feel
On suspension designs with an upper bearing, bearing condition and compatibility can affect rotation.
Wheel alignment
Adjustable mounts may allow camber changes, but the resulting settings should match the vehicle’s needs.
Suspension movement
The mount must allow the movement intended by the suspension design without binding or unwanted looseness.
Signs That a Top Mount May Need Inspection
A clunk near the upper suspension area, unusual steering resistance, visible rubber damage, or movement at the mount can indicate a problem. These symptoms can also come from loose fasteners, worn links, ball joints, bearings, or other suspension components.
Have the suspension checked if you hear persistent knocking, feel unusual steering behavior, or notice a sudden change in handling. If the mount appears loose or damaged, do not continue normal driving until the vehicle has been inspected and any unsafe condition corrected.
Clunking or knocking
Have the upper mount and nearby suspension hardware checked for wear, looseness, and damage.
Rough steering movement
Ask a technician to inspect any upper bearing and confirm that the assembly rotates as designed.
Visible damage
Replace defective parts with components approved for the application.
Common Mistakes When Buying Coilovers With Top Mounts
The most common purchasing mistake is assuming every coilover kit includes all the parts shown in its product photographs. Photos may show optional mounts or a fully assembled display model, while the actual package contains only the components named in the parts list.
Another mistake is buying replacement top mounts before checking whether the coilover kit already includes them. This can create unnecessary costs and may leave you with parts that do not match the new suspension. Confirm the exact kit contents first.
Buyers should also avoid treating all mounts as interchangeable. Differences in bolt spacing, bearing design, shaft dimensions, and suspension geometry can affect fitment. A part that appears similar may still be unsuitable for the vehicle.

Mistake: Relying only on product photos
Use the official parts list and manual to confirm what the seller supplies.
Mistake: Assuming all kits include mounts
Check whether the kit requires factory mounts or separate upper assemblies.
Mistake: Ignoring front and rear differences
Verify the mounting needs for each axle and suspension position.
Mistake: Choosing mounts by appearance
Match part numbers and approved fitment rather than relying on a similar shape.
Mistake: Reusing damaged parts
Inspect original mounts and follow the manufacturer’s replacement instructions.
What to Do Before Installation
Lay out the supplied parts and compare them with the manual before taking the original suspension apart. This makes it easier to spot missing components and resolve fitment questions while the vehicle is still assembled.
Suspension work can involve loaded springs and heavy components. Use suitable lifting equipment, approved support stands, and the manufacturer’s procedure. A spring compressor may be required for certain designs, and some tasks are best left to a qualified technician.
Compare all supplied components
Check the package against the kit’s parts diagram before installation.
Follow specified torque values
Use the correct fasteners and torque specifications for the exact vehicle and coilover kit.
Check alignment requirements
Arrange a wheel alignment when required after installation or when suspension geometry has changed.
Cost Considerations: Are Separate Top Mounts Worth Buying?
The cost of separate top mounts depends on the vehicle, mount design, and whether you need standard replacement parts or adjustable performance components. There is no single price that applies to all coilover systems, so check current prices for the exact application.
A factory-style rubber mount may be appropriate for a road car if it is compatible with the kit. A performance mount with adjustable camber or a spherical bearing may cost more and can bring trade-offs in noise, comfort, and maintenance. Paying more does not guarantee a better result for every driver.
Include related hardware and labor when comparing the cost of kits. If a kit requires the original mounts, inspect their condition before assuming they can be reused. If they are worn, the extra replacement cost may affect the total installation budget.
Factory-style replacement mounts
Consider these when the original design is suitable and the coilover manufacturer approves the configuration.
Adjustable performance mounts
Consider these when their adjustment range is useful for your setup and the kit supports them.
Installation and alignment
Include professional labor and any required post-installation alignment in your total cost.
How to Compare Two Coilover Kits Fairly
Compare the full installed cost rather than the advertised kit price alone. One kit may include the mounts you need, while another may require separate upper assemblies or new factory-style mounts.
Also compare intended use, adjustment features, compatibility, warranty terms, and service requirements. A less expensive kit may cost more overall if it requires additional parts, but the higher-priced kit is not automatically the better choice.
List all required parts
Include mounts, bearings, adapters, and replacement fasteners that the manual requires.
Compare supported features
Check ride-height adjustment, damping adjustment, alignment options, and approved use.
Confirm the final fitment
Verify that every required component is compatible with your exact vehicle.

Frequently Asked Questions
Q
Do coilovers come with top mounts by default?
No. Some coilover kits include new top mounts, while others are designed to reuse factory mounts or require separate parts. Check the parts list and installation manual for the exact kit.
Q
Do I need to buy top mounts separately for coilovers?
Only if the kit requires them and they are not already included. If the kit uses factory mounts, you may be able to reuse the original parts after checking compatibility and condition. Ask the manufacturer if the listing is unclear.
Q
Can I use my stock top mounts with aftermarket coilovers?
Yes, when the aftermarket coilover is designed for the stock mounts and the original parts remain serviceable. Some kits require dedicated mounts or adjustment plates, so never assume the original parts will fit every system.
Q
Do coilovers come with camber plates?
Not always. Some performance kits include adjustable camber plates, while other kits use fixed mounts or factory mounting hardware. Confirm whether camber adjustment is included and supported for your vehicle.
Q
Should I replace top mounts when installing coilovers?
Replace them when they are worn or damaged, when the kit requires new mounts, or when the manufacturer specifies replacement. If the original mounts are compatible and in good condition, reuse may be acceptable when the installation instructions permit it.
Q
Do front and rear coilovers use the same top mounts?
Usually, the mounting requirements differ by axle because front and rear suspension layouts can be different. Some vehicles also use separate spring and shock mounts at the rear. Check the front and rear parts lists individually.
Q
Can I drive with a missing or loose coilover top mount?
Do not drive the vehicle if a required mount is missing, loose, or damaged. The suspension must be assembled with the correct mounting components and fasteners. Have a qualified technician inspect the system and correct the problem before driving.
