BDS is a game changer for your 2011-2019 Chevy Silverado and GMC Sierra 2500 HD with this 6.5" suspension lift kit and FOX 2.5 Coil-Over conversion, with clearance for up to 37" tires. The high-clearance design improves ground clearance, strength, and offroad protection. Up front it uses FOX 2.5 coil-over shocks, heavy duty tubular upper control arms (1.5" OD x .120-wall, TIG welded, indexed ball joint cup for added down travel and camber adjustment), fully boxed and gusseted high strength lower control arms with greaseable ball joints, 1/4" thick high-arched steel crossmembers, multipiece differential relocation brackets, and heavy duty skid plates, with CNC-machined ductile iron steering knuckles, sway bar links, bump stop extensions, stainless brake lines, and CV spacers. The rear uses replacement lift blocks, a u-bolt flip kit for max clearance, and FOX 2.0 Performance Series shocks.
