Fabtech K1179 3.5" Ball Joint UCA Lift Kit with Performance Shocks for 2020-2021 GM 3500HD

The Fabtech K1179 is a comprehensive 3.5-inch suspension lift kit engineered specifically for 2020-2021 GM 3500HD trucks. This system delivers increased ground clearance to accommodate up to 35-inch tires while creating a more level, aggressive stance and enhanced off-road capability.

Tubular Upper Control Arms:

Factory GM upper control arms are replaced with heavy-duty ball joint tubular arms constructed from 1.50-inch OD DOM steel tubing with 0.120-inch wall thickness. These feature oversized high-travel ball joints significantly larger than stock units, providing superior strength for both on-road and off-road use. Fabtech precisely sets the ball joint angle to ensure full suspension travel without binding throughout the entire range of motion. The arms include an additional 1 degree of caster for improved handling and feature 2.25-inch OD x 0.250-inch wall DOM bushing barrels for durability.
