Construction and Appearance. Crafted from .120″ wall, 1.50″ OD 4130 Chromoly tubing, these control arms deliver superior rigidity compared to stock components. They feature 1″ FK stainless PTFE-lined uniballs with 17-4 stainless steel heat-treated pins and misalignments to maintain optimal clearance. Urethane bushings reduce noise and wear, while .250 wall DOM bushing barrels with welded gussets add strength.

Installation. Installation is straightforward and does not require spindle modifications or drilling, as the uniball pins fit factory ball joint tapers, allowing a simple bolt-on upgrade and easy return to stock if desired.
