Fabtech 2011 - 2019 Silverado & Sierra 2500HD / 3500 UniBall Upper Arm # FTS21126

The Fabtech FTS21126 fits 2011 - 2019 GM 2500HD / 3500 series trucks already equipped with a Fabtech 3.5" Lift System. This control arm kit is NOT designed for use on 0" (stock height) or 6" lift equipped trucks. Again, these arms are only for use with a Fabtech 3.5" lift system. Fabtech 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 .120" wall 1.50" OD 4130 Chromoly tubing and 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 FTS21126 Features:
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 uses thick .250" wall DOM tubing on the bushing barrels to prevent failure during severe duty use. The arms themselves are constructed with .120" wall 4130 Chromoly tubing that is the same type of tubing used in Trophy Truck fabrication for unsurpassed strength. The Heat Treated 4340 Uniball Pin is super strong and allows installation without modification to the spindle. 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. The misalignment spacers are constructed out of 17-4 Stainless and these allow the Uniball to travel without interference to the arm or spindle while adding strength to the cross section of the Pin.
