Fabtech 2020+ GM 2500HD / 3500 3.5" Suspension Lift System # K1179M

This Fabtech 3.5" Lift # K1179M is officially designed for use on 2020-22 Chevrolet Silverado 3500HD and GMC Sierra 3500HD trucks. What makes it specific to the 3500 series trucks? This kit includes a set of rear lift blocks. We've found that some of our 2500HD customers prefer this kit because the back of the truck stays a little higher than the back which is helpful if you tow or haul frequently. So on the 3500 trucks this kit provides a pretty level stance... and on the 2500HD trucks the rear is a little higher than the front. 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.

The factory GM upper control arms are replaced with Fabtech’s heavy duty ball joint equipped tubular arms. They are constructed with 1.50" OD DOM steel tubing and feature a high travel ball joint that is sizably larger than the stock one. 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. The rear receives 2" blocks and U-bolts to help level the stance of the vehicle.

Included Fabtech Shocks:
Fabtech includes their Stealth Series monotube shocks with this 3.5" suspension lift. They are a sealed monotube shock that has a Nitrocarb piston rod for corrosion resistance that is more resistant to rock chipping. They will provide a great highway ride with good offroad damping capacity.
