Your Eibach Pro-Truck Rear 1.0" Lift Block kit includes the following components:
- Two (2) 1.0" Lift Blocks - Anodized 6061-T6 Billet Aluminum Construction
- Four (4) Extended U-Bolts
- Hardware (Nuts and Washers for U-Bolts)
- Heavy Duty Steel Centering Pins (assembled with blocks)
Setup & Installation
Installation of suspension components requires specialized tools and knowledge. It is highly recommended that this product be installed by a qualified automotive technician. Improper installation can lead to vehicle instability, component failure, and serious injury.
General Installation Steps (Consult a professional for detailed vehicle-specific instructions):
- Safety First: Park the vehicle on a level surface, engage the parking brake, and use wheel chocks. Lift the rear of the vehicle using a suitable jack and support it securely with jack stands.
- Remove Wheels: Remove the rear wheels to gain access to the suspension components.
- Support Axle: Support the rear axle with a floor jack to relieve tension on the leaf springs.
- Remove Old U-Bolts: Carefully remove the nuts from the existing U-bolts and remove the U-bolts.
- Insert Lift Block: Lower the axle slightly to create space. Position the Eibach lift block between the leaf spring pack and the axle perch. Ensure the centering pin on the block aligns with the hole in the axle perch and the hole in the leaf spring pack aligns with the centering pin on the block.
- Install New U-Bolts: Install the new, extended Eibach U-bolts over the leaf spring pack and around the axle, securing them with the provided nuts and washers.
- Torque U-Bolts: Gradually tighten the U-bolt nuts in a crisscross pattern to the manufacturer's specified torque settings. Refer to your vehicle's service manual for correct torque values.
- Reassemble: Reinstall the wheels and lower the vehicle.
- Alignment: After installation, it is crucial to have a professional alignment performed to ensure proper vehicle handling and tire wear.
Operation
The Eibach Pro-Truck Rear 1.0" Lift Block is a passive component designed to increase the rear ride height of your vehicle by 1.0 inch. Once installed, it works in conjunction with your existing suspension system, particularly well with Eibach PRO-TRUCK Sport Shocks, to provide a lifted stance without altering the spring rate. This modification can improve ground clearance and allow for larger tire fitment, contributing to a more aggressive vehicle appearance and potentially better off-road capability.
Maintenance
The Eibach Pro-Truck Rear Lift Blocks are constructed from durable anodized billet aluminum and require minimal maintenance. However, regular inspection is recommended to ensure continued safety and performance.
- Periodic Inspection: Annually, or every 10,000 miles, inspect the lift blocks, U-bolts, and associated hardware for any signs of wear, corrosion, or damage.
- Torque Check: Re-check the torque of the U-bolt nuts after the first 500 miles of driving and then periodically as part of your vehicle's routine maintenance. Ensure they remain tightened to the vehicle manufacturer's specifications.
- Cleanliness: Keep the components free from excessive dirt and debris. A simple wash with soap and water is sufficient. Avoid harsh chemicals that could damage the anodized finish.
- Damage: If any component shows signs of cracking, bending, or severe corrosion, replace it immediately. Do not attempt to repair damaged suspension components.
Troubleshooting
While the Eibach Pro-Truck Rear Lift Blocks are designed for reliability, certain issues can arise, often related to installation or other vehicle components.
- Uneven Ride Height:
- Cause: Improper installation, incorrect block placement, or issues with other suspension components.
- Solution: Re-check block orientation and U-bolt torque. Inspect leaf springs and shocks for damage or wear.
- Vibrations After Installation:
- Cause: Changes in driveline angles due to lift, loose U-bolts, or unbalanced tires.
- Solution: Verify U-bolt torque. Check driveline angles; shims may be required (not included with this kit). Ensure tires are balanced.
- Clunking or Squeaking Noises:
- Cause: Loose hardware, components rubbing, or worn bushings.
- Solution: Inspect all nuts and bolts for proper torque. Check for clearance issues between components.
- Reduced Ride Comfort:
- Cause: While lift blocks themselves do not change spring rate, they can sometimes expose weaknesses in worn shocks or other suspension components.
- Solution: Consider upgrading to performance shocks, such as Eibach PRO-TRUCK Sport Shocks, designed to complement lifted applications.
If you experience persistent issues, consult a certified automotive technician.
