Product Details

Durable Performance. Superlift Reliability.
Upgrade your rear suspension with Superlift’s premium Lift Block Kit, crafted from high-strength fabricated steel for superior durability and long-lasting performance. These blocks are engineered to enhance towing stability, reduce rear-end sag, and improve overall stance — all while preserving factory ride quality.

Smart Suspension Support.
Superlift lift blocks are designed to help redistribute rear axle load, improving cargo balance and towing performance. The tapered block profile also helps optimize driveline angle to reduce wear on drivetrain components. A tough black powder-coated finish adds lasting corrosion resistance, even in harsh conditions.

Includes High-Strength U-Bolts.
Each kit includes four U-bolts manufactured from low-alloy, high-strength steel, featuring an anti-corrosion Zinc or E-coat finish. Factory-style Hi-nuts and flat washers are included to ensure proper clamping force and secure fitment.

Engineered for Easy Installation.
With a simple bolt-on design, Superlift’s Lift Block Kits install easily and deliver immediate rear suspension improvements without compromising ride quality. Whether you're hauling, towing, or just need to level out your stance, this is a smart, cost-effective upgrade built to last.

Established in 1975 Superlift remains a pioneer in the industry and is one of the few suspension companies operated by true truck and off-road enthusiasts. We are passionate about trucks wheeling and an outdoor lifestyl
