ARP Wheel Stud Kit - M12x1.50, 2.500 in Underhead Length - 5 Pack

ARP wheel studs are forged from 8740 chromoly steel and heat treated to a tensile strength of 190,000 psi, which gives them the shear and elongation strength to survive the acceleration shock and lateral loads that break factory studs. Threads are rolled after heat treating rather than cut, a process ARP uses to raise fatigue life, and every stud is cadmium plated for corrosion protection. Each stud in this kit measures M12 x 1.50 thread with a 2.500 in underhead length and a 0.509 in knurl diameter, and five studs are supplied. Lug nuts are not included.
