4. Installation Guide
This leveling kit is designed for bolt-on installation and is compatible with stock shocks. The spacers can be directly bolted onto the top of the struts without requiring disassembly of the strut assembly.
While the installation is designed to be straightforward, professional installation is highly recommended to ensure proper alignment and safety. Incorrect installation can lead to vehicle instability or damage.
Important Installation Notes:
- Always use appropriate safety equipment, including jack stands and wheel chocks.
- Ensure the vehicle is on a level surface before beginning work.
- Follow all torque specifications for fasteners as per your vehicle's service manual.
- After installation, a professional wheel alignment is mandatory to correct suspension geometry and prevent premature tire wear.
Understanding Lift Height vs. Spacer Thickness:
Due to suspension geometry, the actual lift height achieved will not be a 1:1 ratio with the spacer thickness. The design of the strut spacer alters the angle of the lower control arm, providing an additional lift beyond the physical thickness of the spacer itself.

5. Operating Benefits
Once installed, your maXpeedingrods leveling kit provides several operational benefits:
- Increased Ground Clearance: Adds extra ground clearance, which can be beneficial for off-road driving or navigating uneven terrain.
- Accommodates Larger Tires: Allows for the fitment of larger tires, up to 32 inches, enhancing both aesthetics and off-road capability.
- Eliminates Factory Rake: Levels the vehicle by raising the front to match the rear, providing a more aggressive and balanced stance.
- Maintains Ride Quality: Designed to maintain the smooth factory ride quality, ensuring comfort during daily driving.

6. Maintenance
To ensure the longevity and optimal performance of your leveling kit and vehicle's suspension, consider the following maintenance practices:
- Regular Inspection: Periodically inspect all components of the leveling kit and surrounding suspension parts for any signs of wear, damage, or loose fasteners.
- Cleaning: Keep the components clean from excessive dirt, mud, and road salt, especially if driving in harsh conditions.
- Torque Checks: Re-check the torque of all installation fasteners after the first 500 miles and then periodically as part of your routine vehicle maintenance.
7. Troubleshooting
If you experience any issues after installing your leveling kit, consider the following common troubleshooting steps:
- Uneven Stance: Ensure all components are installed correctly and on the appropriate side of the vehicle. Verify the correct kit was purchased for your specific vehicle model and drivetrain (2WD/4WD).
- Unusual Noises: Check for loose bolts or components making contact with other parts of the suspension or chassis. Re-torque all fasteners.
- Poor Ride Quality: Confirm that the kit is compatible with your stock shocks. If issues persist, consult with a professional mechanic.
- Tire Wear Issues: This is often a sign of incorrect alignment. Ensure a professional wheel alignment was performed after installation.
For persistent issues or concerns, please contact maXpeedingrods customer support.
