4. Operating Considerations

Once installed as part of the 4-inch lift kit, the components from the 51494B-1 box contribute to the vehicle's altered suspension geometry and increased ground clearance. These components are designed to maintain proper alignment and handling characteristics for off-road and on-road use, as intended by the complete lift system.

• After installation, a professional alignment is mandatory to ensure correct steering and tire wear.
• Familiarize yourself with the vehicle's new handling characteristics, especially at higher speeds or during braking.
• Regularly inspect all suspension components, especially after off-road use.

5. Maintenance

Proper maintenance is essential to ensure the longevity and safe operation of your Pro Comp suspension components.

• Regular Inspection: Periodically inspect all bolts, nuts, and other fasteners for tightness. Re-torque to specifications as needed, especially after the first 500 miles and then every 5,000 miles or after severe off-road use.
• Component Check: Visually inspect all suspension components for signs of wear, damage, cracks, or corrosion. Pay close attention to bushings, joints, and welds.
• Cleaning: Keep suspension components clean from excessive dirt, mud, and road salt, which can accelerate wear and corrosion. Use mild soap and water.
• Lubrication: If any components require lubrication (e.g., greaseable joints), follow the lubrication schedule and type of grease specified in the main lift kit manual.

6. Troubleshooting

This section addresses common issues that may arise with suspension components. If you experience persistent problems, consult a qualified suspension technician.

• Unusual Noises (Clunking, Squeaking):
  • Check all fasteners for proper torque. Loose bolts are a common cause of noise.
  • Inspect bushings for wear or damage.
  • Ensure components are not contacting other parts of the vehicle's chassis or frame.
• Premature Wear of Components:
  • Verify proper alignment after lift installation.
  • Ensure correct tire pressure.
  • Review driving habits; aggressive off-road use without proper maintenance can accelerate wear.
• Vehicle Pulling to One Side:
