ONLY fits models with 52" rear leaf springs. If vehicle is equipped with a front sway-bar drop brackets are recommended. (SKU: 1019) Vehicles with factory quad shocks (2 front shocks per side) will simply use a single aftermarket shock. Fitment on this page is based on the manufacturer’s application data.
4-Inch Lift Kit with N3 Shocks, fitment-checked
The 25030 spans the square-body three-quarter-tons (Chevrolet K20 and GMC K25 and K2500, pickups and Suburbans) with 4 inches of lift on replacement leaf springs and application-valved N3 shocks. Rough Country publishes a wheel and tire chart for it running from 35x12.50R15 up to 35x12.50R20, so the tire decision can be made before the kit is ordered rather than after.
What sets this kit apart from its neighbours is the published wheel-and-tire matrix: 35x12.50R15 on a 15x8, 35x12.50R17 and 315/70R17 on a 17x9, and 35-inch and 295/70R18 options on 18-inch wheels, each with the backspacing or offset that makes it work. Some combinations call for trimming and the chart says which. The lift itself is spring-based, with a raised steering arm and a universal U-bolt kit. Confirm the rear springs measure 52 inches, budget 6 to 8 hours, and download the installation guide before starting.
