ARP's head-treated 8740 chrome moly wheel studs are a much-needed replacement for any car engaged in Road racing or drag racing competition. They have a tensile strength of 190,000 psi and are able to easily handle loads (shear) and lateral forces (elongation) found in racing. The studs are cadmium plated for extra durability, measure roughly 25mm longer than stock, and have a bullet nose to ease quick lug nut installation. These extended studs require the use of open ended or extended lug nuts not included.
