The ArcWheel features dependable all steel construction and Improved Torque Retention (ITR) technology. Each stud hole is uncoated and beveled to deliver greater clamp force retention making constant lug tightening a thing of the past. Each wheel goes through a three-step painting process including a zinc phosphate bath, e-coat primer, and silver topcoat on the outboard side. The process ensures an attractive finish and excellent corrosion resistance. The inboard side of each wheel appears differently than the outboard side. The inboard side is e-coated This reduces friction and inhibits corrosion. Our wheels meet all SAE J1204 standards. VALVE STEM NOT INCLUDED. WHEEL ONLY.
