The Eibach 1" Rear Lift Block Kit (Part #LBB1-35-059-03-02) is precision-engineered to deliver a clean, level stance and additional clearance for your 2021+ Ford F-150 4WD. Designed as a bolt-on solution for achieving a perfect leveled look, this kit utilizes high-grade billet aluminum construction and includes heavy-duty U-bolts, hardware, and centering pins for a complete, OE-quality installation.

Built from 6061-T6 billet aluminum, the same material used in aerospace applications, these lift blocks deliver exceptional strength while remaining lightweight and corrosion-resistant. Whether you’re upgrading for improved aesthetics, added clearance, or proper load-leveling, Eibach’s lift kit offers the perfect balance of form, fit, and function.

Level Your Truck with Race-Bred Engineering

Eibach’s lift block systems are more than simple spacers — they’re engineered for precise alignment, load distribution, and long-term reliability. This 1" rear lift block kit levels your F-150’s factory rake without requiring new springs or shocks, making it one of the easiest suspension upgrades available.

Performance Benefits:

• Perfect Leveling Stance: Eliminates the factory front-to-rear rake for a balanced, aggressive look.

• Added Clearance: Accommodates larger tires for improved ground clearance and off-road capability.

• OE-Quality Ride Feel: Maintains factory suspension geometry for a comfortable on-road experience.

• Strength Under Load: Billet aluminum design resists deformation under heavy towing or hauling conditions.

• Corrosion Resistance: Hard-anodized finish provides lasting protection from dirt, salt, and moisture.

This precision lift system enhances both the visual appeal and functionality of your truck — improving stance, clearance, and confidence in every drive.
