2020 GM 2500HD/3500HD 2WD/4WD – 3.5″ Ball Joint UCA Lift Kits

This high quality GM HD 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 heavy duty ball joint tubular arms. They are constructed with 1.50” OD DOM steel tubing and feature a high travel ball joint that is sizably larger than stock. This provides for increased strength both on and offroad. Fabtech sets the ball joint angle to allow for full travel without bind throughout the travel range.

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.

This HD lift kit is available with two shock options. Performance twin tube or the Stealth monotube shocks for a great highway ride with good offroad damping capacity.
