4-Inch Lift Kit with N3 Shocks for 1973–1976 Chevy/GMC K10/K15 4WD

About this kit

4-Inch Lift Kit with N3 Shocks, fitment-checked

Rough Country 11530 is a 4-inch lift kit for 1973–1976 Chevy and GMC half-ton 4WD pickups, Suburbans, and Blazers. Front leaf springs, a raised steering arm, and two pairs of N3 shocks come in the box, and the kit opens up room for tires as tall as 35 inches. Trucks with a factory front sway bar do better with drop brackets, part 1019.

This 4-inch lift kit fits 1973–1976 Chevy and GMC 4WD half-ton applications — K10 and K15 pickups, the matching Suburbans, the K5 Blazer, and the GMC Jimmy — as listed in the fitment section. Application-specific front leaf springs and a raised steering arm handle the geometry at the new ride height, while application-valved N3 shocks control both axles. Rough Country lists the job at 6-8 hours, and a downloadable installation guide is available. If the truck came with a front sway bar, plan on drop brackets, part 1019. Trucks with factory quad shocks use one aftermarket shock per side instead.
