4. Setup and Installation

Installation of the Pro Comp Suspension K1171B Lift Kit requires specialized tools and mechanical expertise. It is strongly recommended that this installation be performed by a qualified automotive technician. Refer to the detailed instructions provided with the physical kit for specific vehicle applications and torque specifications.

General Installation Steps:

1. Preparation: Park the vehicle on a level surface, engage the parking brake, and disconnect the battery.
2. Vehicle Lift: Safely lift the vehicle and support it using appropriate jack stands or a hydraulic lift.
3. Disassembly: Remove existing suspension components as per vehicle-specific instructions. This typically includes shocks, struts, and potentially control arms or leaf springs.
4. Component Installation: Install the new Pro Comp lift kit components, including strut spacers, crossmembers, steering knuckles, lift blocks, and ES9000 shocks. Ensure all bolts are hand-tightened initially.
5. Final Torque: Once all components are in place, lower the vehicle partially to allow the suspension to settle, then torque all fasteners to the manufacturer's specified values.
6. Post-Installation Checks: Reconnect the battery. Check for proper clearance of all components and ensure no lines or wires are pinched.
7. Alignment: Immediately after installation, have a professional alignment performed to correct camber, caster, and toe angles.

5. Operating Considerations

After installing a lift kit, the vehicle's center of gravity will be raised. This can affect handling characteristics, especially at higher speeds or during sharp turns.

• Driving Dynamics: Be aware of increased body roll and a higher risk of rollover compared to a stock vehicle, especially during aggressive maneuvers.
• Braking: Braking distances may be slightly altered.
• Tire Pressure: Maintain correct tire pressure for the installed tires, which may differ from factory recommendations.
• Headlight Aim: Adjust headlight aim to prevent blinding oncoming traffic due to the increased vehicle height.

6. Maintenance

Regular inspection and maintenance are crucial for the longevity and safe operation of your lifted vehicle.

• Initial Check: After the first 500 miles (800 km) of driving, re-torque all suspension fasteners to ensure they remain at specified values.
• Periodic Inspection: Annually or every 10,000 miles (16,000 km), inspect all suspension components for wear, damage, or loose fasteners. Pay close attention to bushings, ball joints, tie rod ends, and shock absorbers.
• Cleaning: Keep suspension components clean, especially after off-road use, to prevent corrosion and premature wear.

7. Troubleshooting

If you experience issues after installation, consider the following:

• Uneven Ride Height: Re-check all components for proper seating and ensure correct parts were installed on the correct side of the vehicle. Verify spring and block orientation.
• Vibrations: Check driveshaft angles, U-joint condition, and tire balance. A professional driveshaft shop may be needed to correct angles if severe.
• Steering Issues (Pulling/Wandering): This is often an alignment issue. Ensure a professional alignment has been performed and is within specifications. Check for loose steering components.
• Noise (Clunking/Squeaking): Inspect all fasteners for proper torque. Check for contact between suspension components and the vehicle frame or body. Lubricate bushings if necessary.

For persistent issues, consult with a qualified automotive technician specializing in lifted vehicles.
