ARP Expands Lineup of Aftermarket Wheel Studs

Wheel studs are an important part of any driveline, and ARP has long focused on manufacturing premium grade replacements for factory and aftermarket applications. In addition to press-in studs for most all domestic and sport compact vehicles, the company has screw-in studs for aftermarket axles. The most recent addition to the line, p/n 100-7738, has a 1/2-20 thread and an underhead length of 1.950”.

Like other ARP wheel studs, they are manufactured from 8740 chrome moly steel and heat-treated to a nominal tensile strength of 190,000 psi (some 26% stronger than Grade 8 hardware) and cadmium plated for extra durability. Threads are rolled (not cut) to provide up to 10-times better fatigue life.

Obtaining the optimum stud length is an important consideration, and ARP offers 1/2-20 screw-in studs up to 3.470” underhead length. Many racing associations require the stud to protrude from the lug nut a distance equal to its diameter.

ARP fasteners are proudly manufactured in-house at the firm’s California facilities. Details on the complete product line, as well as important tech info, are in the new 2023 catalog. View it online at www.ARP-bolts.com or request your free printed copy.
