Fabtech 2007-2013 Silverado & Sierra UniBall Upper Arm # FTS21128

This Fabtech Uniball Upper Control Arm # FTS21128 is designed for use on 2007, 2008, 2009, 2010, 2011, 2012 and 2013 model year Chevrolet Silverado 1500 and GMC Sierra 1500 series 2wd and 4x4 trucks. Fabtech designed their UniBall Upper Arm Kits for severe duty use. The main benefit the Fabtech design has is it will work on a stock height truck and most aftermarket suspension systems. These Fabtech FTS21128 Upper Control Arms replace the thin stock upper control arms that are prone to flex and ball joint failure with heavy duty construction designed for aggressive offroad driving. Fabtech Uniball Upper Control Arms directly replace the factory upper control arms for use on stock, aftermarket or Fabtech suspensions providing additional strength and reliability to the vehicle.

The Fabtech FTS21128 is a direct replacement for the factory upper arm on the 2007-2013 Chevrolet Silverado 1500, GMC Sierra 1500, Chevrolet Tahoe, Chevrolet Suburban 1500 and GMC Yukon and Yukon XL 1500. Please note that these arms will ONLY fit 1500 series vehicles. Will NOT fit 2007 Classic Edition trucks.

Fabtech FTS21128 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.
