Rough Country 29730A is a 6-inch lift kit for 2001-2010 Chevy Silverado 2500 HD and GMC Sierra 2500 HD 4WD trucks, plus 2001-2004 Silverado 2500 and Sierra 2500 4WD. The kit ships with two N3 shock pairs, cast knuckles for the driver and passenger sides, a crossmember box, and a torsion drop box. Trucks with factory 17-inch wheels need replacements of 17 inches or larger.
This 6-inch lift kit fits 2001-2010 Chevy Silverado 2500 HD and GMC Sierra 2500 HD 4WD trucks, the 2007 Classic versions, and 2001-2004 Silverado 2500 and Sierra 2500 4WD models across the trims listed in fitment. Plan on minor front differential modification, and pick up a torsion bar unloading tool before you start: Rough Country lists that tool under SKU 1067. Running a 35x12.50 tire can call for front valance trimming, and gas-engine trucks may need the exhaust rerouted for front driveshaft clearance. A downloadable installation guide is available.
