Skyjacker D400BRK 4 Inch Softride Suspension Lift Kit with Front Leaf Springs and Rear Blocks

The Skyjacker D400BRK is a 4-inch Softride suspension lift kit engineered for classic full-size 4x4 SUVs. This kit utilizes replacement front leaf springs paired with a rear block-and-u-bolt system to deliver a lifted ride height without sacrificing on-road comfort or off-road capability.

Skyjacker's proprietary Softride® leaf springs are individually shot-peened with hard steel pellets at high velocity for added durability and strength. Tapered leaf ends distribute loads more evenly and promote greater flex, while Teflon® wear pads between the leaves and bolt-style spring clips eliminate binding and reduce friction for a smoother, longer-lasting ride.

The rear of the vehicle retains the OEM rear leaf springs, with a high-quality block and U-bolt kit providing the rear lift. The kit includes front leaf springs, leaf spring bushings, bushing sleeves, U-bolts, and rear lift blocks — everything needed for a complete front and rear lift installation.
