The Fabtech Performance front shock is a high-velocity dampener made to work with Fabtech 6-inch lift systems for 2020 GM 2500HD/3500HD 4WD applications. It pairs twin-tube hydraulic construction with high-flow 9-stage valving and a closed-cell foam insert to reduce shock fade at speed. Hardened 9/16 in. chrome piston rod, polyurethane bushings and a 1 3/8 in. OD piston give controlled ride quality for lifted trucks.
