Fabtech K1179DL Ball Joint Upper Control Arm Lift Kit with Dirt Logic Shocks - 3.5

The Fabtech K1179DL is a premium 3.5-inch suspension lift kit engineered specifically for 2020-2021 GM 3500HD trucks. This complete system delivers the increased ride height needed to accommodate 35-inch tires while providing enhanced off-road capabilities and a more aggressive, leveled stance.

Heavy-Duty Tubular Upper Control Arms:

This kit replaces the factory GM upper control arms with Fabtech's reinforced ball joint tubular arms, constructed from 1.50-inch OD DOM steel tubing with 0.120-inch wall thickness. The arms feature a high-travel ball joint that is significantly larger than stock, delivering superior strength for demanding 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. An additional 1 degree of caster is built in for improved steering stability and handling. The 2.25-inch OD x 0.250-inch wall DOM bushing barrels provide exceptional durability.

Forged Torsion Bar Keys:

Heavy-duty forged torsion bar keys replace the factory units, allowing for additional ride height adjustment that works in conjunction with the new upper control arms for precise tuning.

Dirt Logic 2.25 Shocks:

This kit includes Fabtech's top-tier Dirt Logic 2.25 shocks, featuring stainless steel bodies and NitroSteel piston rods for maximum corrosion resistance and longevity. These premium shocks deliver superior ride quality on pavement and exceptional damping performance for aggressive off-road driving.

Rear Leveling Components:

The rear receives 2-inch lift blocks and U-bolts to level the vehicle's stance and complement the front lift height.

This complete 3.5-inch lift kit combines high-quality components that enhance both the strength and reliability of your GM 3500HD while giving it a commanding presence on or off the road.
