Installation Guide

This component box is part of a larger 6-inch lift kit system. The following steps are general guidelines. Always refer to the specific instructions provided with your complete lift kit (e.g., K1083B/K5072B) for detailed, model-specific procedures.

1. Preparation: 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.
2. Disassembly: Follow your lift kit's instructions to remove existing suspension components as required. This may include shocks, springs, control arms, or other related parts.
3. Component Box Integration: Install the components from the 51021B-3 box according to the lift kit's instructions. This typically involves mounting brackets, spacers, or other structural elements that facilitate the 6-inch lift.
4. Hardware Installation: Use the provided installation hardware. Ensure all bolts are tightened to the manufacturer's specified torque values. Do not overtighten or undertighten fasteners.
5. Reassembly: Reinstall the remaining suspension components, wheels, and any other parts removed during disassembly, following the lift kit's instructions.
6. Final Checks: Lower the vehicle to the ground. Perform post-installation checks as outlined in the next section.

Post-Installation Checks

After installation, it is crucial to perform these checks to ensure proper function and safety.

• Torque Verification: Re-check all fasteners for proper torque after the vehicle has been driven approximately 50-100 miles.
• Alignment: A professional wheel alignment is mandatory after installing any suspension lift kit. This ensures correct steering geometry and tire wear.
• Brake Lines and Hoses: Inspect all brake lines, ABS lines, and other hoses for proper routing and clearance. Ensure they are not stretched, pinched, or rubbing against other components.
• Steering Components: Check all steering linkages for proper function and clearance throughout the full range of steering motion.
• Test Drive: Perform a cautious test drive in a safe area to check for any unusual noises, vibrations, or handling characteristics.

Maintenance

Regular inspection and maintenance will prolong the life of your suspension components.

• Periodically inspect all bolts and nuts for tightness, especially after off-road use.
• Check suspension components for signs of wear, damage, or corrosion.
• Keep components clean from excessive dirt and debris.

Troubleshooting

If you encounter issues after installation, consider the following:

• Unusual Noises: Re-check all fasteners for proper torque. Inspect for any components rubbing or contacting each other.
• Poor Handling/Steering: Verify that a professional wheel alignment has been performed. Check tire pressure. Inspect steering components for looseness.
• Uneven Ride Height: Ensure all components were installed correctly and on the appropriate sides of the vehicle (if applicable).

For persistent issues, contact a qualified automotive technician or PRO COMP customer support.
