Overview
This lift kit for the 2019–2024 Chevrolet Silverado Trail Boss and GMC Sierra AT4 1500 (4WD) builds off the factory suspension geometry to improve stance, performance, and capability. Up front, the kit includes FOX Factory Race Series 3.0 Internal Bypass (IBP) remote reservoir coil-over shocks paired with BDS heavy-duty tubular upper control arms for increased strength and suspension travel. Out back, fabricated steel lift blocks, longer U-bolts, and a complementary set of FOX Factory Race Series 3.0 IBP shocks round out the setup. On Trail Boss and AT4 models, this kit yields approximately 1.5 inches of lift over factory ride height, with clearance for up to 35-inch tires (Chevy) or 33-inch tires (GMC).
FOX Factory Race Series 3.0 Internal Bypass shocks deliver position-sensitive damping technology and Dual Speed Compression (DSC) adjustment. Patented Internal Bypass technology provides multiple zones of damping control, producing more force progressively to control hard bottom-outs, prevent harsh top-outs, and provide an initial catch for landings. Finned external reservoirs and aluminum shock bodies manage fluid temperatures, while Type III anodization resists corrosion on the 3-inch diameter bodies.
