The BDS Suspension BDS1802FS / 1802H 4-inch suspension lift kit for the Chevy Silverado 1500 diesel truck will allow for the fitment of up to 35-inch diameter tires for a great off-road look. This is done without sacrificing ride quality and handling while fully FMWSS 126 compliant.

This premium quality suspension lift kit is built around a set of 1/4 inch thick steel laser cut high clearance cross members designed to get maximum clearance and provide a rock-solid mounting point for the factory lower control arms. The front strut spacer gives additional height to the vehicle. Three piece heavy-duty front skid plates connect the cross members while protecting steering and driveline components. Correct steering geometry is maintained using new ductile iron steering knuckles that keep the ESC system compatible with tubular upper control arms. CV axle angles are kept at a minimum using a multi-point front differential relocation system. The rear end is lifted using 3-inch tall axle blocks (replacing factory block) with extended ubolts.
