5. Setup and Installation
Disclaimer: Professional installation is recommended. Improper installation can lead to vehicle damage or personal injury. Ensure the vehicle is on a level surface and properly supported before beginning any work. Always wear appropriate safety gear.
5.1. Required Tools
A comprehensive list of tools will be provided in the detailed installation guide included with your kit. General tools may include:
- Jack and Jack Stands
- Wheel Chocks
- Socket Wrench Set
- Torque Wrench
- Pry Bar
- Spring Compressor (if applicable for strut disassembly)
5.2. Pre-Installation Checks
- Inspect all components for any manufacturing defects or shipping damage.
- Ensure the vehicle is clean and free of debris around the suspension components.
- Review the specific torque specifications for your vehicle's suspension components.
5.3. General Installation Steps (Summary)
This is a general overview. Refer to the detailed instructions provided with your kit for specific steps and diagrams.
- Safely lift the vehicle and secure it on jack stands. Remove wheels.
- Front Installation: Disconnect necessary suspension components to remove the front strut assembly. Install the billet aluminum front strut spacers on top of the strut assembly. Reinstall the strut assembly and reconnect all components, ensuring proper torque.
- Rear Installation: Disconnect necessary suspension components to allow the rear axle to drop sufficiently. Install the rear coil spring spacers between the coil spring and the vehicle's frame/axle. Reassemble components, ensuring proper torque.
- Differential Drop Installation: Install the differential drop spacers to correct the front differential angle after lifting, reducing stress on CV joints.
- Skid Plate Drop Installation: Install skid plate drop spacers to ensure proper clearance and alignment of the skid plate after the differential drop.
- Reinstall wheels and lower the vehicle.
- Perform a final check of all fasteners to ensure they are tightened to specification.
After installation, it is highly recommended to have a professional alignment performed on your vehicle to ensure correct steering and tire wear.
6. Operating Considerations After Lift Kit Installation
After installing the leveling lift kit, your vehicle's driving characteristics will change. Be aware of the following:
- Increased Ground Clearance: The kit provides a 3-inch front and 2-inch rear lift, increasing ground clearance. This enhances off-road capability but may alter the vehicle's center of gravity.
- Handling: The vehicle's handling may feel different, especially at higher speeds or during sharp turns. Drive cautiously until you are accustomed to the new feel.
- Braking: Braking performance should not be significantly affected, but always test brakes in a safe environment after any suspension modification.
- Tire Clearance: The lift allows for larger tires, but always check for proper clearance under full suspension articulation and steering lock.
- Off-Road Use: The kit is designed to improve off-road performance. However, always exercise caution and drive within your vehicle's and your own capabilities.

7. Maintenance
Regular inspection and maintenance are crucial for the longevity and safety of your lift kit and vehicle.
- Initial Check (500 miles): After approximately 500 miles of driving, re-torque all fasteners installed or loosened during the lift kit installation. This is critical as components can settle.
- Routine Checks: Periodically inspect all suspension components, including the lift kit spacers, bolts, and nuts, for any signs of wear, damage, or loosening.
- Cleaning: Keep suspension components clean, especially after off-road use, to prevent dirt and debris buildup that could accelerate wear.
- Alignment: Recheck wheel alignment periodically, especially if you notice uneven tire wear or changes in steering.
8. Troubleshooting
This section addresses common issues that may arise after installing a lift kit.
- Uneven Ride Height:
- Possible Cause: Incorrect installation of spacers, or components not fully settled.
- Solution: Re-verify installation steps and ensure all components are correctly seated and torqued. Allow for a break-in period for components to settle.
- Vibrations:
- Possible Cause: Driveline angles altered, loose fasteners, or unbalanced tires.
- Solution: Ensure differential drop kit is correctly installed. Check all fasteners for proper torque. Have tires balanced and alignment checked.
- Noise (Clunking/Squeaking):
- Possible Cause: Loose components, rubbing parts, or worn bushings.
- Solution: Inspect all areas where new components were installed for proper clearance and tightness. Lubricate bushings if necessary.
- Steering Issues (Pulling/Wandering):
- Possible Cause: Incorrect wheel alignment.
- Solution: Immediately get a professional wheel alignment.
