- Eye Protection: Wear safety glasses or goggles to protect your eyes from debris.
- Proper Tools: Use the correct tools for each step of the installation process.
- Torque Specifications: Adhere strictly to all manufacturer-recommended torque specifications for fasteners. Overtightening or undertightening can lead to component failure.
- Post-Installation Checks: After installation, perform a thorough inspection of all components and ensure proper wheel alignment.
- Road Test: Conduct a cautious road test in a safe area to verify proper function and handling before normal operation.
3. Package Contents
Verify that all components are present and undamaged before beginning installation. The package should contain:
- One pair of 2.5" Front Lift Coils (Hot Wound Steel, Powder Coated Grey)

Note: If any parts are missing or damaged, do not proceed with installation. Contact MaxTrac customer support immediately.
4. Setup and Installation
This section outlines the general steps for installing the MaxTrac 872171F front lift kit. Specific vehicle models may require additional steps or specialized tools. Refer to your vehicle's service manual for detailed instructions on removing and installing factory suspension components.
- Prepare Vehicle: Park the vehicle on a level surface. Engage the parking brake. Loosen the front wheel lug nuts. Raise the front of the vehicle using a hydraulic jack and support it securely with jack stands under the frame rails. Remove the front wheels.
- Disconnect Components: Disconnect the sway bar end links, brake lines (if necessary, ensure proper support to prevent damage), and ABS sensor wires from the factory strut assembly.
- Remove Factory Strut/Coil Assembly: Carefully unbolt the lower strut mount from the control arm and the upper strut mounts from the frame. Remove the entire factory strut and coil assembly from the vehicle.
- Disassemble Factory Strut (if applicable): If your vehicle uses a coil-over strut, you will need a spring compressor to safely remove the factory coil spring from the strut. Exercise extreme caution when using a spring compressor.
- Install MaxTrac Coils and Fox Shocks: Install the new MaxTrac 2.5" front lift coils onto the Fox 2.0 Performance Series Front Shocks. Ensure all bushings and hardware are correctly oriented.
- Install New Assembly: Carefully position the new coil and shock assembly into the vehicle. Secure the upper mounts first, then the lower mount to the control arm. Do not fully tighten bolts until the vehicle is at ride height.
- Reconnect Components: Reconnect the sway bar end links, brake lines, and ABS sensor wires. Ensure all lines and wires are routed correctly and not pinched.
- Install Wheels and Lower Vehicle: Reinstall the front wheels and hand-tighten lug nuts. Carefully lower the vehicle until it is resting on its own weight.
- Final Torque: With the vehicle at ride height, tighten all suspension fasteners to the manufacturer's specified torque values. Refer to your vehicle's service manual for these specifications.
- Wheel Alignment: A professional wheel alignment is mandatory after installing any suspension lift kit. This ensures proper handling, tire wear, and safety.
5. Post-Installation Checks
After completing the installation, perform the following checks:
- Re-torque All Fasteners: After approximately 500 miles of driving, re-check and re-torque all suspension fasteners to ensure they remain secure.
- Check for Clearance: Ensure there is adequate clearance between all suspension components, tires, and vehicle chassis at full suspension travel and steering lock.
- Inspect Brake Lines and Wires: Verify that brake lines, ABS sensor wires, and other cables are not stretched, pinched, or rubbing against any components.
- Test Drive: Perform a short, cautious test drive to check for any unusual noises, vibrations, or changes in handling.
6. Maintenance
Regular maintenance helps ensure the longevity and performance of your MaxTrac suspension components:
- Periodic Inspection: Visually inspect all suspension components, including coils, shocks, bushings, and fasteners, every 3,000-5,000 miles or during routine vehicle service.
- Check for Wear: Look for signs of wear, cracks, or damage on bushings, shock bodies, and coil springs.
- Clean Components: Keep suspension components clean from excessive dirt, mud, and road salt, which can accelerate wear.
- Re-torque Fasteners: Periodically re-check the torque on all critical fasteners, especially after off-road use or heavy loads.
7. Troubleshooting
If you encounter issues after installation, refer to the table below for common problems and potential solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Unusual noises (clunking, squeaking) | Loose fasteners, worn bushings, component interference. | Inspect all fasteners for proper torque. Check bushings for wear. Verify clearance between components. |
| Uneven ride height | Improper installation, damaged coil spring, incorrect component pairing. | Re-check installation steps. Inspect coil springs for damage. Ensure correct parts were installed on each side. |
| Poor handling or steering | Incorrect wheel alignment, loose steering components, damaged shocks. | Obtain a professional wheel alignment. Inspect steering and suspension components for looseness or damage. |
| Excessive vibration | Unbalanced tires, loose driveline components, incorrect pinion angle (if applicable). | Check tire balance. Inspect driveline components. Consult a professional for driveline angle adjustments if necessary. |
