ARP studs are professional-quality fasteners for your wheels. They are manufactured from premium-grade, heat-treated 8740 chromoly steel, nominally rated at 190,000 psi tensile strength, and cadmium plated for extra durability. Styles and sizes are available to fit all popular applications; plus, they can easily handle the tremendous acceleration shock loads and lateral forces found in racing applications. ARP wheels studs are must-have replacements for competition vehicles.
