The Fabtech K1180DL is a premium 3.5-inch suspension lift kit engineered specifically for 2020-2021 GM 3500HD trucks. This complete system elevates ride height to accommodate up to 35-inch tires while improving off-road capability and creating a level, aggressive stance from front to rear.

Heavy-Duty Tubular Upper Control Arms:

Factory upper control arms are replaced with Fabtech's reinforced ball joint tubular arms, built from 1.50-inch OD DOM steel tubing with .120-inch wall thickness. These arms feature an oversized high-travel ball joint significantly larger than stock, providing exceptional strength for demanding on-road and off-road use. The ball joint angle is precision-set to allow full suspension travel without binding throughout the entire range of motion. Each arm includes an additional 1 degree of caster for improved steering stability and includes 2.25-inch OD x .250-inch wall DOM bushing barrels for maximum durability.

Front shocks are equipped with remote aluminum reservoirs that increase oil capacity and cooling efficiency, ensuring consistent damping performance in rugged terrain. These premium shocks deliver exceptional ride quality on pavement while providing excellent control during aggressive off-road driving.
