2019-21 4WD Chevy Silverado Trail Boss, GMC Sierra AT4 1500 (Diesel) 4" Dirt Logic 2.5 Coilover lift kit, Dirt Logic 2.25 shocks

The new GM Silverado Trail Boss and Sierra AT4 models come with a factory 2" lift. By installing the Fabtech 4" lift kit, the result will be the same as non-Trail Boss and non-AT4 models that have a 6" lift kit. This allows for 35" tires. The IFS suspension design for the Silverado Trail Boss and Sierra AT4 1500 has a number of features that make this Fabtech lift kit the one to choose. Expect improved on and off-road driving with zero bump steer that reduces driver fatigue. A clean appearance is achieved by keeping the tires under the fenders and near stock track width with Fabtech's proprietary steering knuckle geometry. Tight spots can be maneuvered easily with lock to lock turning radius. The crossmembers are 1/4" thick steel with OE style alignment cam pins that use the factory cams for easy adjustment. High speed vibration is eliminated with the triple front differential mounts that reposition the differential. The 4" of lift is provided by Dirt Logic 2.50 Coilovers for outstanding ride quality. This system is designed for aggressive offroad use without sacrificing road feel. The rear Dirt Logic 2.25 shocks offer a balanced ride by aiding in damping.
