Description

Factory upper control arms run out of travel and angle fast once a GM HD gets leveled or lifted. The Axiom Supply Upper Control Arm System fixes that with true double-shear arms welded from identical laser-cut 3/16" steel plates, corrected geometry, and a pair of AX6292 Grade 12.9 bolt-on upper ball joints already installed in the deal. Whether the truck is stock height, leveled, or fully lifted, this is the arm built for heavy-duty use.

• Corrected geometry restores proper operating angles and improves droop travel on leveled and lifted trucks
• Dual-position ball joint mounting (above or below the plate) for extra alignment flexibility
