Fabtech 2020 GM K2500HD 3.5in Uniball Upper Control Arms

The Fabtech Silverado 2500 Uniball Upper Control Arms for the 3.5 Inch System are constructed with .120-Inch wall 4130 Chromoly tubing. They feature 1.50-Inch OD 1-Inch FK Stainless PTFE Uniballs, which allow for 9 inches of front wheel travel. This system helps level the vehicle's stance by counteracting the factory nose-down rake, without requiring modifications to the rear suspension. An optional 1-inch rear block kit is available. The kit includes heavy-duty ductile iron steering knuckles and forged adjustable torsion bar keys to prevent CV bind, as well as performance twin-tube shocks with a closed-cell insert and 9-stage high-velocity valving for superior dampening and to prevent shock fading at high speeds.
