Fitment on this page is based on the manufacturer’s application data.
4-Inch Lift Kit with N3 Shocks, fitment-checked
Cut for the heavier three-quarter-ton chassis, the 19630 raises Chevrolet K20 and GMC K25 4WD pickups and Suburbans by 4 inches on replacement leaf springs at both ends. N3 shock pairs are valved for the load rather than for a lighter truck. It fits only vehicles with 52-inch rear leaf springs.
The parts list is built around the heavier chassis: replacement springs front and rear, a raised steering arm shared with the C10 and K10 platform, a front installation kit and a universal U-bolt kit, plus N3 shock pairs. Confirm the rear leaf springs measure 52 inches before ordering, because that single measurement is the usual reason one of these turns out to be the wrong kit. A front sway bar calls for drop brackets, and a truck with factory quad shocks needs the matching quad shock kit. A downloadable installation guide is available.
