5. Installation Instructions

These instructions are a general guide. Refer to your vehicle's service manual for specific torque specifications and additional details. It is recommended to work on one side of the vehicle at a time.

5.1. Preparation

1. Park the vehicle on a flat, level surface.
2. Engage the parking brake and place wheel chocks behind the rear wheels (when working on the front) or in front of the front wheels (when working on the rear).
3. Loosen the lug nuts on the wheels you will be removing.
4. Jack up the vehicle and support it securely with jack stands under the frame. Ensure the axles are hanging freely.
5. Remove the wheels.

5.2. Front Installation

1. Disconnect the sway bar links from the axle.
2. Disconnect the lower shock mount bolt.
3. Carefully lower the axle to allow the coil spring to be removed. A spring compressor may be necessary.
4. Install the front coil spring spacer on top of the original coil spring. Ensure it seats correctly.
5. Reinstall the coil spring assembly.
6. Install the front shock bracket to extend the shock absorber. Secure it with the provided hardware.
7. Reattach the lower shock mount bolt and sway bar links.
8. Install the brake line bracket to ensure adequate slack for the brake lines.
9. Repeat for the other front side.

5.3. Rear Installation

1. Disconnect the sway bar links from the axle.
2. Disconnect the lower shock mount bolt.
3. Carefully lower the axle to allow the coil spring to be removed.
4. Install the rear coil spring spacer on top of the original coil spring. Ensure it seats correctly.
5. Reinstall the coil spring assembly.
6. Install the rear shock extender bracket. Secure it with the provided hardware.
7. Reattach the lower shock mount bolt and sway bar links.
8. Repeat for the other rear side.

5.4. Final Steps

1. Reinstall the wheels and hand-tighten the lug nuts.
2. Lower the vehicle completely off the jack stands.
3. Torque all lug nuts to the manufacturer's specifications.
4. Torque all suspension bolts to the manufacturer's specifications.

6. Operating Considerations

6.1. Post-Installation Checks

• Alignment: A professional wheel alignment is mandatory immediately after installation to prevent premature tire wear and ensure proper vehicle handling.
• Headlight Adjustment: Adjust your vehicle's headlights to their proper level to avoid blinding oncoming traffic.
• Fluid Lines: Inspect all brake lines, ABS lines, and other fluid lines to ensure they are not stretched, pinched, or rubbing against any components.
• Fasteners: After approximately 500 miles of driving, re-torque all suspension fasteners to ensure they remain secure.

6.2. Driving Characteristics

The 3" lift will increase your vehicle's ground clearance, allowing for larger tires (up to 33" recommended) and improved off-road performance. While designed to maintain a smooth ride with stock shocks, be aware of the altered center of gravity, which may slightly affect on-road handling characteristics, especially during cornering.

7. Maintenance

Regular inspection of your lift kit components is crucial for safety and longevity.

• Periodic Inspection: Annually, or after severe off-road use, inspect all components of the lift kit for signs of wear, damage, or corrosion.
• Fastener Checks: Periodically check and re-torque all bolts and nuts associated with the suspension and lift kit.
• Cleaning: Keep the components clean from excessive dirt, mud, and salt, which can accelerate corrosion.

8. Troubleshooting

• Uneven Ride Height: Double-check that the correct spacers are installed on the correct axles (front vs. rear) and that they are seated properly. Ensure all components are fully tightened.
• Unusual Noises: Inspect all connections for loose bolts or components rubbing against each other. Re-torque all fasteners.
• Poor Handling/Steering Issues: This often indicates a need for a professional wheel alignment. Also, check for proper installation of brake line brackets and sway bar links.
• Brake Line Tension: If brake lines appear stretched, ensure the brake line relocation brackets are correctly installed and providing sufficient slack.
