• Vehicle Lift or Jack and Jack Stands
• Standard Mechanic's Tool Set (sockets, wrenches, ratchets)
• Torque Wrench
• Wheel Chocks
• Penetrating Lubricant (optional)

4.2. Installation Steps (General)

1. Prepare Vehicle: Park the vehicle on a level surface, engage the parking brake, and chock the rear wheels.
2. Lift Vehicle: Safely lift the front of the vehicle using a vehicle lift or jack stands, ensuring the front wheels are off the ground.
3. Remove Wheels: Remove the front wheels.
4. Disconnect Suspension Components: Carefully disconnect necessary suspension components to allow for removal of the front strut assembly. This typically includes sway bar links, tie rod ends, and lower control arm bolts.
5. Remove Strut Assembly: Unbolt and remove the factory front strut assembly from the vehicle.
6. Install Strut Spacer: Attach the Pro Comp strut spacer to the top of the factory strut assembly using the provided hardware. Ensure proper orientation as per any markings on the spacer.
7. Reinstall Strut Assembly: Reinstall the modified strut assembly back into the vehicle, securing it with factory hardware.

9. Torque All Fasteners: Using a torque wrench, tighten all fasteners to the vehicle manufacturer's specifications.
10. Reinstall Wheels: Reinstall the front wheels and lower the vehicle.
11. Final Checks: Perform a final visual inspection to ensure all components are correctly installed and tightened.
12. Wheel Alignment: A professional wheel alignment is mandatory after installing any suspension lift kit to prevent premature tire wear and ensure proper vehicle handling.

5. Operating Considerations

After installing the Pro Comp LL5025 Level Lift Kit, be aware of the following operational changes:

• Center of Gravity: The vehicle's center of gravity will be slightly raised, which may affect handling, especially during sharp turns or emergency maneuvers.
• Braking: Braking performance should not be significantly affected, but always test braking in a safe environment after any suspension modification.
• Tire Clearance: The lift kit provides additional tire clearance, allowing for larger tires if desired. Ensure any new tires clear all suspension and body components throughout the full range of steering and suspension travel.

6. Maintenance

Regular maintenance is crucial for the longevity and safe operation of your vehicle after a lift kit installation.

• Initial Re-torque: Re-torque all suspension fasteners, especially those related to the lift kit, after the first 500 miles of driving.
• Periodic Inspection: Periodically inspect all suspension components, including the strut spacers, for signs of wear, damage, or loose fasteners. This should be done during routine vehicle maintenance.
• Alignment Checks: Have your wheel alignment checked annually or whenever you notice uneven tire wear or changes in steering behavior.

7. Troubleshooting

If you encounter issues after installation, consider the following common troubleshooting steps:

• Uneven Stance:
  • Verify that the correct spacers are installed on the correct side of the vehicle (if applicable).
  • Ensure all components are fully seated and torqued.
• Unusual Noises (Clunking, Squeaking):
  • Check all fasteners for proper torque.
  • Inspect for any components making contact with each other that should not be.
  • Ensure all bushings are properly seated and lubricated if necessary.
• Steering or Handling Issues:
  • Immediately have a professional wheel alignment performed.
  • Inspect steering and suspension components for damage or incorrect installation.

If problems persist, contact Pro Comp customer support or a qualified automotive technician.
