- Material: Constructed from 6061 aluminum alloy with T6 for increased hardness, high strength, and durability. Features high-quality precision parts.
- 55CrSi Steel Springs: Made from alloy steel using a cold winding technique for sag-free performance.
- Durable Rubber TPV Dust Boots: Protect piston shafts from dirt and debris, extending component life.
- Sturdy Lower Brackets: Manufactured from carbon steel to withstand heavy loads without bending, deforming, or breaking.
- Solid Rubber Bump Stops: Integrated to prevent harsh bottoming out.
- Anti-rust Perches and Locking Rings: Designed for durability and lightweight performance.
- Heavy-duty Lower Mount: Anti-rust and robust construction.

5. Installation
Installation of coilovers requires mechanical expertise and specialized tools. If you are not confident in your ability to perform this installation safely and correctly, seek assistance from a professional mechanic.
General Installation Steps (Consult a service manual for your specific vehicle for detailed instructions):
- Prepare the Vehicle: Park the vehicle on a level surface, engage the parking brake, and loosen the lug nuts on the wheels. Jack up the vehicle and secure it with jack stands. Remove the wheels.
- Remove OEM Suspension: Disconnect any brake lines, ABS sensors, or sway bar links attached to the existing strut/shock assembly. Unbolt the lower mounting points and the upper strut/shock mounts. Carefully remove the old suspension components.
- Prepare New Coilovers: For front coilovers, you may need to transfer the OEM top hat (upper mount) to the new coilover assembly if not pre-assembled. Ensure all collars are loose for initial height adjustment.
- Install New Coilovers: Install the new coilover assemblies, securing the upper mounts first, then the lower mounting points. Reattach any disconnected lines or links.
- Initial Height Adjustment: Before fully tightening, set an approximate ride height. Refer to Section 6 for detailed adjustment procedures.
- Tighten All Fasteners: Torque all bolts and nuts to the vehicle manufacturer's specifications.
- Reinstall Wheels: Mount the wheels and hand-tighten lug nuts. Lower the vehicle to the ground and torque lug nuts to specification.
- Post-Installation Checks: Bounce the vehicle to settle the suspension. Check for any clearance issues or loose components.
- Wheel Alignment: A professional wheel alignment is crucial after any suspension component replacement or adjustment.

6. Height Adjustment
The coilovers allow for precise ride height adjustment. Always adjust both sides of the vehicle (front or rear) equally to maintain balance.
Image 6.1: Diagram illustrating the height adjustment mechanism of the coilovers.
Procedure:
- Lift Vehicle: Safely lift the vehicle so the wheels are off the ground and the suspension is unloaded.
- Loosen Locking Collars: Use the provided C spanners to loosen the locking collars on the coilover body.
- Adjust Height: Rotate the main adjustment collar to raise or lower the vehicle. Turning clockwise typically lowers the vehicle, while counter-clockwise raises it. Make small, incremental adjustments.
- Secure Locking Collars: Once the desired height is achieved, tighten the locking collars firmly against the adjustment collar to prevent movement.
- Repeat for Other Side: Ensure the corresponding coilover on the opposite side is adjusted to the exact same height.
- Lower Vehicle and Settle: Lower the vehicle to the ground and drive a short distance or bounce the suspension to allow it to settle. Re-measure the ride height and make further fine adjustments if necessary.
- Final Alignment: After all height adjustments are finalized, a professional wheel alignment is essential.
7. Operating Considerations
After installing coilovers, your vehicle's driving characteristics will change. Be aware of the following:
- Improved Handling: The coilovers are designed to provide improved handling and a more responsive feel, especially for street use.
- Ride Comfort: While designed for comfort, a lowered vehicle with performance suspension may have a firmer ride than stock.
- Clearance: Be mindful of reduced ground clearance, especially over speed bumps, potholes, and steep driveways, to avoid damage to the vehicle's undercarriage or suspension components.
- Driving Style: Adapt your driving style to the new suspension setup.

8. Maintenance
Regular inspection and maintenance will ensure the longevity and performance of your coilovers.
- Regular Inspection: Periodically inspect the coilovers for any signs of damage, leaks, corrosion, or loose components. Check the dust boots for tears.
- Cleanliness: Keep the coilover bodies and threads clean, especially after driving in harsh conditions (e.g., snow, salt, dirt). This prevents corrosion and ensures smooth adjustment.
- Lubrication: Apply a thin layer of anti-seize grease to the adjustment threads if they become stiff or difficult to turn.
- Torque Check: Re-check the torque on all mounting bolts and nuts after the first 500 miles and periodically thereafter.
- Wheel Alignment: If you notice uneven tire wear or changes in handling, have your wheel alignment checked.
9. Troubleshooting
If you experience issues with your coilovers, consult this section for common problems and solutions.
Image 9.1: Visual indicators for when suspension struts may need attention, including difficult steering control, uneven tire wear, rattling or clunking noises, and uncomfortable driving.
| Problem | Possible Cause | Solution |
|---|---|---|
| Uneven Ride Height | Incorrect adjustment; Settling of springs | Re-measure and adjust coilover height evenly on both sides. Allow suspension to settle. |
| Clunking/Rattling Noises | Loose mounting bolts; Components hitting chassis; Damaged top hat/bushings | Check all mounting bolts for proper torque. Inspect for clearance issues. Verify top hat and bushing integrity. |
| Excessive Bounciness/Harsh Ride | Incorrect spring preload; Damper malfunction; Improper installation | Ensure spring preload is set correctly (if applicable). Inspect dampers for leaks or damage. Re-check installation. |
| Oil Leaks from Damper | Damaged seal; Manufacturing defect | Contact customer support for warranty or replacement. |
| Poor Handling/Steering | Incorrect wheel alignment; Loose components; Damaged suspension parts | Get a professional wheel alignment. Inspect all suspension components for damage or looseness. |
