About this part
3-Inch Lift Knuckles, fitment-checked
Rough Country 7501 is a 3-inch lift knuckle kit for 1999-2007 Chevrolet Silverado 1500 and GMC Sierra 1500 RWD trucks, including HD and Classic applications. It fits only trucks running 6-lug wheels. Bolt-on installation with no vehicle modification called for, and Rough Country lists an install time of 4-5 hours.
These 3-inch lift knuckles for the 1999-2007 Chevrolet Silverado 1500 and GMC Sierra 1500 RWD raise the front end for added ground clearance while keeping the factory ride characteristics intact. Coverage extends across Silverado 1500 HD, Sierra 1500 HD, and the 2007 Classic body styles, plus the 1999-2000 Chevrolet C1500. Confirm your wheels use a 6-lug pattern before ordering, since that is the deciding fitment qualifier here. The knuckles bolt in place of the factory units with no cutting called for, and a downloadable Rough Country installation guide is available to walk through the sequence.
