Designed specifically for 2019–24 Chevy Silverado 1500 Trail Boss and GMC Sierra 1500 AT4 4WD models, this system provides an additional 1.5″ of ride height to accommodate full-size 33/12.50R tires on 18″ or 20″ wheels. Since these models come factory-equipped with a 2″ lift, adding this 1.5″ kit results in a stance comparable to a standard GM 1500 fitted with a 3.5″ lift kit, offering improved tire clearance without compromising drivability.
Fabtech’s 1.5″ Upper Control Arm Lift Kit is engineered to avoid suspension bind at full droop while maintaining proper suspension geometry. The system features premium stainless steel Dirt Logic 2.5 Coilovers, recognized for exceptional durability, corrosion resistance, and superior damping through the stainless steel body and NitroSteel® piston rod. These Coilovers deliver outstanding performance both on and off the road.
High-strength tubular Upper Control Arms with heavy duty ball joints ensure the correct alignment range at the new ride height. Due to the updated GM suspension design, no differential drop brackets are required to maintain proper CV axle operation. Rear lift is provided by 1″ blocks and u-bolts, though some owners may omit the rear blocks to achieve a level stance. Complementing the system, Dirt Logic 2.25 stainless steel rear shocks offer excellent ride quality and enhanced off-road damping capability.
