7.5-Inch M1 Strut Suspension Lift Kit

The Rough Country 7.5-inch suspension lift kit is engineered for 2007-2013 Chevy Silverado 1500 and GMC Sierra 1500 models, excluding "Classic" 2007 versions. It provides aggressive lift height while maintaining drivability and preserving factory geometry. This kit allows for the fitment of 35-40 inch tires and features Rough Country's engineered crossmember for maximized ground clearance and M1 strut package for a level front-to-rear stance. Key components include precision-engineered steering knuckles designed for 18-inch or larger wheels, a laser-cut high-clearance crossmember, M1 loaded monotube struts for the front, and M1 monotube shocks paired with 6.5-inch fabricated lift blocks featuring anti-axle-wrap technology for the rear. Important fitment and installation notes include: it does not fit 2007 "Classic" models. 18-inch or larger wheels are required; factory 20-inch wheels work, but smaller sizes may interfere with steering geometry. AWD models will require a new aftermarket driveshaft (SKU 5083.1) to eliminate vibration; 4WD models do not need this modification. The kit is backed by a Rough Country Lifetime Replacement Warranty on structural components and a 3-Year warranty on finish and shocks.
