3.5″ Uniball UCA Lift Kit w/ Dirt Logic 2.25 Resi Shocks – K1182DL



2020-24 Chevy Silverado 3500HD | GMC Sierra 3500HD 4WD

This high quality GM 3500HD lift kit offers an increased ride height for enthusiasts looking to run a 35" tall tire with enhanced offroad capabilities. The stance of the vehicle will become more level front to rear for an aggressive look.

The factory GM upper control arms are replaced with Fabtech’s Uniball Upper Control Arms that provide additional wheel travel with an extra degree of caster compared to stock UCA’s. They are constructed of the finest material with .120" wall 1.50" OD 4130 Chromoly tubing. High quality 1" FK Stainless PTFE lined Uniball bearings are utilized in place of ball joints. These super stout Control Arms are designed for increased longevity in rugged offroad conditions while providing a more positive on road feel.

Fabtech’s forged torsion bar keys replace the factory units and allow for additional ride height adjustment to work in conjunction with the new upper control arms.

The rear receives 2" blocks and U-bolts to help level the stance of the vehicle.

Fabtech offers their top of the line Dirt Logic 2.25 shocks with this quality 3500HD lift kit. They are constructed with a stainless steel body and a NitroSteel® piston rod for maximum corrosion resistance and durability. The front shocks comes with remote aluminum reservoirs to help cool the shock oil for more consistent damping in rugged terrain. These high quality Dirt Logic shocks will provide a superior ride quality both on and offroad with excellent damping for offroad use.

This 3.5" HD lift kit comes with high quality components that add strength and reliability to the vehicle while giving it a commanding presence.
