4. Setup & Installation

This section provides a general overview of the installation process. Refer to the detailed instructions provided with your physical kit for specific steps and torque values. Due to the complexity and safety implications, professional installation is strongly advised.

4.1. Pre-Installation

1. Verify all kit components are present and undamaged.
2. Park the vehicle on a level surface and engage the parking brake.
3. Loosen lug nuts on all wheels.
4. Lift the front of the vehicle using a floor jack and support it securely with jack stands under the frame. Remove the front wheels.
5. Repeat for the rear of the vehicle.

4.2. Front Installation

1. Disconnect necessary components to allow the front strut assembly to be removed (e.g., sway bar links, brake lines, ABS lines).
2. Remove the lower and upper strut mounting bolts and carefully remove the entire strut assembly.
3. Install the front strut spacer on top of the strut assembly, ensuring proper orientation and securing with provided hardware.
4. Reinstall the modified strut assembly into the vehicle, securing all mounting points and reattaching disconnected components.

4.3. Rear Installation

1. Support the rear axle with a jack.
2. Remove the factory U-bolts.
3. Carefully lower the axle slightly to insert the rear lift block between the leaf spring and the axle pad. Ensure the block is correctly aligned.
4. Install the new, longer U-bolts over the leaf spring and around the axle, securing them with the provided hardware.
5. Raise the axle back into position and torque U-bolts to specifications.

4.4. Post-Installation

1. Reinstall all wheels and torque lug nuts to factory specifications.
2. Lower the vehicle to the ground.
3. Perform a final check of all fasteners to ensure they are tightened to specifications.
4. Drive the vehicle a short distance and re-check all fasteners.
5. Immediately schedule a professional wheel alignment. This is crucial for vehicle safety and performance after any suspension modification.

5. Operating Considerations

After installing the Pro Comp 65225K Suspension Lift Kit, your vehicle's driving characteristics will change. Be aware of the following:

• Center of Gravity: The vehicle's center of gravity will be raised, which may affect stability, especially during sharp turns or emergency maneuvers. Drive cautiously until you are accustomed to the new handling.
• Tire Clearance: The lift kit provides additional clearance for larger tires. Ensure that any new tires installed do not rub against suspension components or fender wells during full steering lock or suspension travel.
• Braking: While the kit itself does not directly alter braking performance, larger and heavier tires can increase stopping distances.
• Headlight Aim: The vehicle's headlight aim may be affected by the lift. Adjust headlights to ensure proper visibility and to avoid blinding oncoming traffic.

6. Maintenance

Regular inspection and maintenance are crucial to ensure the longevity and safe operation of your suspension lift kit.

• Periodic Torque Checks: After the first 500 miles and then every 5,000 miles, re-check the torque on all fasteners installed with the lift kit, especially U-bolts and strut mounting hardware.
• Component Inspection: Regularly inspect all suspension components for signs of wear, damage, or corrosion. Pay close attention to bushings, bolts, and the integrity of the spacers and blocks.
• Alignment: Maintain proper wheel alignment. Re-align the vehicle if you notice uneven tire wear or changes in steering feel.

7. Troubleshooting

If you encounter issues after installing the lift kit, consider the following common troubleshooting steps:

• Uneven Stance: Double-check that the correct spacers/blocks were installed on the appropriate axles and that all components are seated correctly. Verify tire pressures are even.
• Vibrations: Vibrations can indicate an issue with driveline angles, tire balance, or loose components. Re-check all fasteners and consider having the driveline angles inspected by a professional.
• Steering Issues/Pulling: This is almost always an alignment issue. Ensure a professional alignment has been performed.
• Noise (Clunking/Squeaking): Inspect all mounting points for loose hardware or components rubbing against each other. Lubricate bushings if necessary.

For persistent or severe issues, consult a qualified automotive technician.
