4in Lift Block Kit

The Rough Country 4-inch Lift Block Kit is a pair of leaf spring blocks engineered to raise the ride height of trucks and off-road vehicles by four inches. Built from steel and finished in black powder coat, this suspension component delivers the structural integrity required for sustained off-road use while maintaining consistent load support and handling characteristics.

Lift blocks function by increasing the angle of the leaf springs, which elevates the frame relative to the axles. At 4 inches of lift height, this kit provides meaningful ground clearance gains without requiring replacement of springs or shocks, making it an efficient option for owners seeking modest suspension geometry changes. The black powder coat finish offers corrosion resistance in varied weather and terrain conditions. Each block is precision manufactured to ensure even weight distribution across the leaf spring pack, critical for maintaining axle alignment and preventing premature wear on suspension components.

This kit is designed for truck owners looking to increase ground clearance for larger tire fitment, improve approach and departure angles for off-road travel, or simply gain a more commanding driving position. The pair configuration ensures both sides of the vehicle receive identical lift, preserving chassis balance and suspension geometry. Installation typically occurs between the leaf spring pack and the axle housing, and the blocks are stacked with existing factory components. Rough Country lift blocks are commonly used in pickup restoration projects, trail-ready builds, and everyday trucks operated in rough terrain.
