6-Inch Lift Kit with N3 Shocks, fitment-checked
Rough Country 220N3A takes 2001-2010 Chevy Silverado 2500 HD and GMC Sierra 2500 HD two-wheel-drive trucks up 6 inches on N3 shock pairs, front and rear. The kit uses one-piece forged knuckles, a crossmember and a torsion drop, and it clears 35x12.50 tires. Dually trucks are excluded, and installation calls for a torsion bar unloading tool.
N3 shocks front and rear make this the base damping choice in the 6-inch HD lift family, covering 2001-2010 Silverado 2500 HD and Sierra 2500 HD in two-wheel drive along with the 2001-2004 Sierra 2500 and 2007 Classic trucks. Lift comes from one-piece CNC-machined knuckles working with a crossmember and torsion drop, keeping the factory ride character while opening room for 35x12.50 tires: a size that can call for front valance trimming. Dually trucks do not fit, wheels must be 17 inches or larger where the truck came with 17-inch wheels, and part 1067 unloads the torsion bars.
