Belltech has extended our product line to now include mid-range 4inch Suspension Lift Kit Systems for the 2019-2021 Silverado/Sierra 1500 2WD/4WD trucks. Precision engineered cooperatively in the US and Germany, this suspension lift kit system is the best riding lift kit on the market-period. Designed to ride, handle and become more capable off road than any other GM kit on the market. Belltech's precisely engineered lift kits include custom designed front height adjustable Street Performance struts and rear Street Performance Twin Tube shocks. These lift kits not only improve your ride quality but also retain factory alignment specifications while retaining the factory adjustment cams. The replacement tubular upper control arms correct poor ball joint working angles and maintain factory droop travel without concern of over extension. You can always expect Belltech quality parts on these kits with heavy duty, black zinc hardware and 1/4" thick steel skid plate for added strength and protection to tackle any tough on or off-road condition. Another great benefit of using this lift kit is its easy installation that is a direct bolt on solution that requires no cutting or welding. Note: Excludes AT4 or models equipped with factory Magride or adaptive ride control.
