5. Installation / Setup
Due to the complexity and safety implications, professional installation is strongly recommended. The following is a general overview and not a substitute for detailed, vehicle-specific service manual instructions.
- Prepare Vehicle: Park the vehicle on a level surface, engage the parking brake, and block the rear wheels. Lift the front of the vehicle and support it securely with jack stands. Remove the front wheels.
- Remove OEM Components: Carefully remove the original front shock absorbers and torsion keys according to your vehicle's service manual.
- Install New Torsion Keys: Install the maXpeedingrods forged torsion keys. These keys are designed to provide the specified lift.
- Install New Shock Absorbers: Mount the new maXpeedingrods front shock absorbers. Ensure all mounting hardware is correctly torqued to manufacturer specifications.
- Reassemble: Reinstall the front wheels and lower the vehicle.
- Post-Installation: A professional wheel alignment is mandatory after installing any suspension lift components to correct camber, caster, and toe angles. Failure to do so can result in poor handling, premature tire wear, and unsafe driving conditions.

6. Operating Considerations
The maXpeedingrods lift leveling kit is designed to provide a comfortable ride suitable for daily driving and light trail use. The twin-tube design and natural rubber bushings contribute to noise absorption and vibration reduction.
- The 1.5-2 inch front lift enhances load capacity and stability, particularly beneficial for heavy-duty applications.
- Increased ground clearance can reduce the risk of chassis scratches during off-road or uneven terrain driving.
- Always drive responsibly and be aware of the altered vehicle dynamics due to the lift.
7. Maintenance
Regular inspection and maintenance are crucial for the longevity and safe operation of your suspension system.
- Periodically inspect all suspension components for signs of wear, damage, or loose fasteners.
- Check shock absorbers for leaks or damage to the dust boots. Replace if necessary.
- Ensure all bolts and nuts are torqued to the manufacturer's specifications.
- Keep suspension components clean, especially after off-road use, to prevent corrosion and debris buildup.
8. Troubleshooting
If you experience any issues after installation, consider the following common troubleshooting steps:
- Uneven Ride Height: Verify that torsion keys are correctly installed and adjusted. Ensure all components are seated properly.
- Excessive Noise: Check all fasteners for proper torque. Inspect bushings for damage or improper seating.
- Poor Handling/Steering Issues: Confirm that a professional wheel alignment was performed after installation. Re-check all suspension connections.
- Shock Absorber Malfunction: Inspect shocks for visible damage or fluid leaks. If a shock is suspected to be faulty, contact customer support.
For persistent issues, consult a qualified mechanic or contact maXpeedingrods technical support.
