How To Adjust Coilover Height


If you are an automotive enthusiast or a performance-oriented driver, you probably know the importance of having the right suspension setup for your vehicle. Coilovers are an excellent choice for those seeking better handling, improved ride comfort, and the ability to adjust their ride height. In this article, we will walk you through the process of adjusting coilover height, ensuring that you have the expertise and confidence to fine-tune your vehicle’s suspension system to meet your specific needs, based on the car types coilover design or height may vary such as coilover for 350z.

How to Adjust Coilover Height

Understanding Coilovers and Their Components

Before we delve into the adjustment process, let’s understand what coilovers are and their key components. Coilovers are a type of suspension system that integrates a coil spring and shock absorber into a single unit. The primary components of a coilover system include:

  • Coil Spring: Provides support and helps maintain the vehicle’s ride height.
  • Shock Absorber: Dampens vibrations and impacts for a smoother ride.
  • Adjustable Perch/Ring: Allows you to change the spring’s position, thus altering the ride height.

Preparing for Coilover Adjustment

Before you begin the adjustment process, make sure you have the necessary tools, including a floor jack, jack stands, wheel chocks, and appropriate wrenches. Additionally, ensure that your vehicle is on a level surface, and the handbrake is engaged.

Measure the Current Ride Height

To set a baseline and ensure precise adjustments, measure the current ride height of your vehicle. Measure from the wheel center to the fender’s highest point on all four corners and record the measurements.

Adjustment Techniques for Coilovers

a. Threaded Body Coilovers

Threaded body coilovers feature a threaded sleeve that moves up and down the shock body, allowing for ride height adjustment. To raise the ride height, twist the threaded sleeve counterclockwise, and to lower it, twist it clockwise.

b. Lower Bracket Coilovers

Lower bracket coilovers use a separate adjustable bracket that allows you to change the spring’s position without altering the shock’s length. Loosen the locking collar, adjust the bracket’s position, and tighten the locking collar to set the desired ride height.

c. Spring Perch Coilovers

Spring perch coilovers have a movable perch where the spring sits. By raising or lowering the perch, you can adjust the ride height. Loosen the locking collar, move the perch, and re-tighten the locking collar to secure the adjustment.

Making Incremental Adjustments

When adjusting coilover height, it is essential to make incremental changes. Adjust one corner at a time, and use the measurements you took earlier to ensure all four corners have the same ride height. Keep in mind that the left and right sides should also be equally adjusted to maintain balance.

Test Drive and Fine-Tuning

After making adjustments, take your vehicle for a test drive. Pay attention to its handling, ride comfort, and stability. If needed, fine-tune the coilovers to achieve the optimal ride height that suits your driving preferences.


Adjusting coilover height is a valuable skill that allows you to optimize your vehicle’s suspension to suit your driving style and preferences. By following the steps outlined in this comprehensive guide, you can confidently fine-tune your coilovers, achieving the perfect balance between performance, comfort, and aesthetics. Remember to make incremental adjustments, prioritize safety, and seek professional help if needed. Enjoy the enhanced driving experience with your properly adjusted coilovers!
