Introducing the redesigned GM 3.5-inch Suspension Lift by Rough Country Suspension Systems with some exciting upgrades to make your off-road experience even better. These updated kits now feature our critically acclaimed M1 shock absorbers and rear blocks. This kit also includes Rough Country's Performance M1 Struts for improved tire contact with the road and increased stability and performance.These struts are engineered to fit perfectly on each intended application, and feature a pre-installed coil spring for easy installation without the need for strut disassembly. Simply remove your factory strut and replace with this easy, convenient system. The result is an increased ride height that mimics the factory responsiveness and handling of the OE strut.
