The Baja Kits Chevy Silverado Long Travel Race kit is built to conquer Baja in 2WD or 4WD. All factory suspension components are replaced with our CAD engineered, box construction upper and lower control arms and fabricated upright. We designed this kit with optimum geometry and by having the shock mount, limit strap tab and bump stop mount self- locate on the factory pivot points; installation is simple and straight forward. Countless hours were spent working with King Shocks development engineers to perfect the custom tuned, 3.0 inch coilover and 3.0 inch bypass shock package on each corner. A 3.5 inch bypass shock option is also available.( Shocks Sold Separately ) Just install the kit and go.
