Fabtech’s Uniball upper control arm kit replaces factory ball-joint arms to strengthen front suspension for aggressive off-road use or as an add-on to Fabtech 2- and 6-inch systems. Tubular 1.25 in OD chromoly construction houses 1 in ID stainless American uniballs that attach to the factory spindle without drilling, providing increased strength and alignability while eliminating the upper ball joint.
