About this kit
2-Inch Leaf Spring Lift Kit, fitment-checked
Rough Country 18630 raises three-quarter-ton 1973–1976 Chevy K20 and K20 Suburban and GMC K25, K25 Suburban and K25/K2500 trucks by 2 inches using new front and rear leaf springs, a bushing kit, U-bolts, and two pairs of N3 shocks. Rear springs must measure 52 inches eyelet to eyelet.
This one is aimed at the heavier half of the 1973–1976 GM 4WD lineup: Chevrolet K20 and K20 Suburban in 1975–1976, GMC K25 and K25 Suburban in 1975–1976, and the K25/K2500 pickup and Suburban in 1973–1974. New 2-inch leaf springs go in front and rear along with a bushing kit, a universal U-bolt kit, and an installation kit, and two pairs of N3 shocks handle the damping. Confirm the rear springs measure 52 inches. A front sway bar calls for drop brackets, part 1019, and factory quad shock trucks add kit Q20022. Shipping weight: 215 lb.
