      Description. Take your 2019-2021 Chevrolet Silverado Trail Boss or GMC Sierra AT4 to new heights with Superlift’s 4” lift system. Superlift Suspension’s Lift Kits have a strong, modern die-formed design made with the strongest materials to give you a suspension kit that can withstand the most challenging terrain. Superlift Suspension intentionally over-builds our suspension kits to be the best. Our uniquely engineered design adds strength and durability, along with bonus features that others do no offer.

      This kit includes front knuckles, front strut spacers, ¼” plate steel control arm cross-members, differential drops, differential skid plate, fabricated rear blocks, u-bolts, and rear shocks. All required parts are included to make sure your Chevrolet Silverado or GMC Sierra handles and performs in all conditions.
