The Tuff Country 4-inch suspension lift for 2007–2013 GMC Sierra 1500 4x4 reintroduces upper control arm design to lift the front 4 inches and rear 2 inches. The kit uses tubular upper control arms, coil/strut spacers, differential drops and a replacement skid plate (for 2007–2013 4WD models) to preserve factory geometry. It’s presented as an affordable, simple-to-install way to gain clearance without sacrificing ride.
