Description

The Superlift Suspension 3059 is a 5-inch rear block and U-bolt kit designed to enhance towing stability, reduce rear-end sag, and improve vehicle stance. Crafted from high-strength fabricated steel, these blocks help redistribute rear axle load for better cargo balance and towing performance. The tapered block profile optimizes driveline angle to minimize drivetrain wear. The kit includes four high-strength steel U-bolts with a corrosion-resistant finish, along with factory-style Hi-nuts and flat washers.
