About this kit

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

A 6-inch lift kit for 1973-1976 Chevrolet and GMC 4WD trucks and SUVs — Blazer, K5 Blazer, K10, K15, Jimmy, and Suburban applications. The kit box holds front leaf springs, a rear add-a-leaf pack, a raised steering arm, and two N3 shock pairs, with clearance for tires up to 37 inches.

The 12530 lifts 1973-1976 Chevrolet and GMC 4WD trucks and SUVs six inches on application-specific front leaf springs, with a rear add-a-leaf pack handling the back half and a raised steering arm correcting the steering geometry that comes with the new ride height. Two N3 shock pairs are valved for this application. Plan on 6-8 hours in the driveway and use the downloadable Rough Country installation guide. Trucks running a factory front sway bar should add drop brackets, part 1019; trucks with factory quad shocks use one aftermarket shock per side.
