Overview
The Fabtech K1151DL is a 6-inch performance system with Dirt Logic shocks for the 2019 and 2021 Chevrolet Silverado 1500 and GMC Sierra 1500. The description says it is for 2WD trucks, and the rated lift range is 6 to 7 inches. Fabtech describes it as the Dirt Logic version of its 2WD 6-inch system, with the stainless steel shocks matched to the lift.
The front uses Dirt Logic 2.5 coilovers that provide the 6 inches of lift, and the rear uses Dirt Logic 2.25 shocks. The rear is lifted with a 5-inch block and U-bolt system. Fabtech says the setup gives outstanding ride quality on the road and off it, and the company says the independent front suspension keeps the tires under the fenders while maintaining a clean stance. Fabtech says the steering knuckle geometry gives excellent lock-to-lock turning, which helps the truck maneuver in tight spots.
