Fabtech’s Uniball Upper Control Arms are designed to replace the factory ball joint arms to strengthen the front suspension for aggressive offroad use. They are an excellent upgrade due to the additional one degree of caster when running oversized tires

The tubular Upper Control Arms feature 1.50” OD, .120" wall 4130 chromoly tubing with 1" diameter Stainless Steel FK Uniballs that attach to the factory spindle taper with 17-4 stainless steel pins. Large urethane pivot bushings at the frame help to reduce chassis noise and vibration.

These Uniball Upper Control Arms have been designed to work with stock height vehicles or with Fabtech 6" RTS Lift kit.
