Part #: FTS21288

2020 Chevy Silverado 2500HD/3500HD, GMC Sierra 2500HD/3500HD 4WD - Fits 3.5in Lifts Only. Fabtech's Uniball Upper Control Arms provide increased strength to the front suspension by replacing the stock ball joint upper arms that can become worn and eventually fail under aggressive offroad use. These heavy duty upper arms are designed for longevity in rugged offroad conditions. They also feature additional caster compared to stock upper arms for superior on road use with oversized tires. The top quality construction of these arms include .120in wall 1.50in OD 4130 Chromoly tubing and American made 1in FK Stainless PTFE lined Uniballs. The 17-4 Stainless Steel heat treated Uniball pins fit into the factory ball joint tapers without modification to the spindle for easy return to stock feature. Fabtech uses 17-4 Stainless steel for the misalignments that provide proper clearance of the 1in Uniballs throughout the travel range. On the frame side of the upper arms, there are quality urethane bushings that help reduce road noise while providing longevity. Fabtech's Uniball Upper Control Arms are an excellent upgrade to stock or lifted suspension systems for drivers that demand the best for their vehicle. Features: Arms eliminate factory upper ball joint w/ super strong 1in ID Stainless Steel American Uniball for increased suspension strength. Additional caster is built into Arms for enhanced align ability with oversized tires. 1.50in OD .120in wall 4130 Chromoly tubing reduces flex found in stock arms for more positive road feel. 17-4 Heat treated Uniball pin fits into factory ball joint taper without modification to the spindle for easy return to stock feature. 17-4 Stainless steel misalignments for proper clearance of large Uniballs throughout the travel range. 250 wall DOM bushing barrels with welded gussets for strength.

MIA's Description

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.
