Fabtech 2019+ Silverado & Sierra UniBall Upper Arm # FTS21274

The Fabtech FTS21274 is a direct replacement for the factory upper arm on the 2019, 2020, 2021, 2022 and 2023 model year Chevrolet Silverado 1500 and GMC Sierra 1500 trucks. These control arms are also 100% compatible on trucks equipped with the TrailBoss and AT4 package. These control arms will not fit any Classic or LD series truck built on the older design. These control arms are only for use on the revised 2019 and up model years. 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.

Fabtech FTS21274 Features:

The top quality construction of these arms include .120" wall 1.50" OD 4130 Chromoly tubing and American made 1" 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 1" 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 Uniball Upper Control Arms are an excellent upgrade to stock or lifted suspension systems for drivers that demand the best for their vehicle.

These Fabtech Upper Arms feature a welded gusset that reinforces the Uniball cup to the Chromoly Arm tubes for exceptional strength. The Uniball used is a large 1" ID Stainless Steel PTFE lined American made FK Uniball bearing that is indexed to the Arm to allow for increased travel when utilizing Dirt Logic Coilover shocks. Bushing barrels and Chromoly Arm tubes are strengthened by welded gussets to distribute load across both parts rather than at just the point of the welded barrel. Greaseable polyurethane bushings provide a smooth connection to the frame without squeaks.

Fabtech UniBall Control Arms can be removed and the truck returned back to stock without issue if necessary. This is ideal for trucks that are leased that will must be turned in with a stock suspension.
