GMC's 2019 Sierra 1500 features an impressive all-new design that's built from the ground up, with aggressive angles and head-turning stylings that fit in beautifully when transformed with Rough Country's 6in Suspension Lift. This kit lifts and levels your vehicle for a commanding stance and enough clearance to run 35x12.50 tires on 10in wide wheels. Rough Country has engineered this kit to provide optimal suspension geometry while retaining the factory ride quality, giving you enhanced off-road capabilities without sacrificing the handling and smooth ride that makes this truck so impressive. Rough Country's 6in Suspension lift retains the stock track width, allowing for up to a 10in wide wheel with 4.5in backspacing. Each kit includes front and rear crossmembers and a skid plate for enhanced chassis strength as well as cast steel knuckles for incredible durability and performance. Includes Rough Country's Lifetime Replacement Guarantee! Fitment Notes: This product is specifically designed to fit GMC Denali models with Magnetic Ride Control and Chevy Silverado models with Adaptive Ride Control, but does not fit ZR2 or AT4 models, nor those with composite leaf springs or factory wheels. It requires cutting and drilling for installation, and aftermarket wheels of 20 inches or larger with 4.5-inch backspacing are necessary. Testing wheel fit prior to installation is recommended.
