6. Safety Information
Working on vehicle suspension systems can be hazardous. Always prioritize safety and follow these guidelines:
- Professional Installation: It is strongly recommended that these coilovers be installed by a qualified automotive technician.
- Vehicle Support: Always use appropriate jack stands to support the vehicle securely when working underneath it. Never rely solely on a jack.
- Personal Protective Equipment (PPE): Wear safety glasses, gloves, and appropriate clothing to protect against injury.
- Tools: Use the correct tools for each step of the installation process.
- Spring Compression: Coil springs are under high tension. Exercise extreme caution when handling or compressing springs. Use a proper spring compressor if necessary.
- Torque Specifications: Adhere to the vehicle manufacturer's torque specifications for all fasteners.
7. Installation (Setup)
This section provides a general overview of the installation process. Specific steps may vary depending on your vehicle's exact configuration. Refer to a service manual for your specific Chevy Camaro model for detailed instructions.

General Installation Steps:
- Prepare Vehicle: Park the vehicle on a level surface, engage the parking brake, and loosen the lug nuts on the wheels.
- Lift and Secure: Safely lift the vehicle using a hydraulic jack and secure it with jack stands. Remove the wheels.
- Remove OEM Suspension: Carefully disconnect and remove the original shock absorbers and springs. This typically involves detaching brake lines, ABS sensors, sway bar links, and upper/lower mounting bolts.
- Transfer Top Mounts: If your new coilovers do not come with top mounts, you will need to transfer the OEM top mounts from your original suspension to the new coilover assemblies. Use a spring compressor if necessary.
- Install New Coilovers: Install the maXpeedingrods coilover assemblies into the vehicle's suspension points. Ensure all bolts are finger-tight initially.
- Reconnect Components: Reattach brake lines, ABS sensors, and sway bar links.
- Initial Tightening: With the vehicle still on jack stands, tighten all mounting bolts to the manufacturer's specified torque.
- Lower Vehicle: Carefully lower the vehicle to the ground.
- Final Torque: With the vehicle's weight on the suspension, perform a final torque check on all fasteners.
- Alignment: After installation, a professional wheel alignment is mandatory to ensure proper handling and tire wear.
8. Adjustment (Operating)
Your maXpeedingrods Coilovers allow for ride height adjustment. The damping value is factory preset and not user-adjustable.

Ride Height Adjustment:
- Lift Vehicle: Safely lift the vehicle so the wheels are off the ground, relieving pressure from the suspension.
- Loosen Locking Collars: Use the provided adjustment wrenches to loosen the locking collars on the coilover body.
- Adjust Height: Rotate the main spring seat collar to raise or lower the vehicle. Turning clockwise typically lowers the vehicle, while counter-clockwise raises it. Make small, even adjustments to all four coilovers.
- Tighten Locking Collars: Once the desired height is achieved, securely tighten the locking collars against the spring seat to prevent movement.
- Lower Vehicle and Test: Carefully lower the vehicle and drive it a short distance to allow the suspension to settle. Re-measure the ride height and make further adjustments if necessary.
- Re-alignment: Any significant change in ride height will require a professional wheel alignment.
9. Maintenance
Regular maintenance helps prolong the life and performance of your coilovers.
- Regular Inspection: Periodically inspect the coilovers for any signs of damage, leaks, or loose components. Check dust boots for tears.
- Cleaning: Keep the coilover bodies and threads clean, especially after driving in harsh conditions (e.g., snow, salt, dirt). Use a mild soap and water solution.
- Lubrication: Apply a thin layer of anti-seize lubricant to the adjustment threads annually to prevent seizing and facilitate future adjustments.
- Torque Check: Re-check the torque on all mounting bolts and locking collars after the first 500 miles of driving and then periodically (e.g., every 10,000 miles).
10. Troubleshooting
This section addresses common issues you might encounter.
Common Issues and Solutions:
- Noise (Clunking/Squeaking):
- Cause: Loose mounting bolts, worn bushings, or improper installation.
- Solution: Re-check all mounting bolts for proper torque. Inspect bushings for wear and replace if necessary. Ensure top mounts are correctly installed.
- Uneven Ride Height:
- Cause: Uneven height adjustment, suspension not settled.
- Solution: Re-measure and adjust all coilovers to ensure even height. Drive the vehicle briefly to allow suspension to settle before final measurement.
- Poor Handling/Steering:
- Cause: Incorrect wheel alignment, loose components, or damaged coilover.
- Solution: Get a professional wheel alignment. Inspect all suspension components for damage or looseness.
- Oil Leakage from Damper:
- Cause: Damaged seal or damper.
- Solution: If a significant oil leak is observed, the damper unit may be faulty and require replacement. Contact customer support.
