universal fit logo


  • Fabtech | Part Number: FABFTS21127
  • Fitment:Direct Fit
  • Position:Front Upper


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 .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’s Uniball Upper Control Arms are an excellent upgrade to stock or lifted suspension systems for drivers that demand the best for their vehicle.

Q: I have a 2.5 torsion key lift in the front of my 2011 duramax 4wd you guys did the alignment and set the heigh after I installed them .the issue I have is the upper control arm hits the stop on the frame will these arms eliminate that problem Answer this question

A: Marty- Thank you for your question. The Fabtech Control Arm Kit will help with the bottom on the frame mount where the arm is bottoming out on the down travel. They also have a pad on them so the do not impact metal on metal. The issue is you will need to return the upper control arm to more stock geometry. A kit that would do this can be found here http://jo.my/xii3xd
