Because races can be won or lost in the pits, the engineers at ARP set about to create the ultimate oval track competition wheel stud that facilitates accurate wheel positioning and quicker release/tightening of lug nuts.
They're made from heat-treated 190,000 psi chrome moly steel and feature precision J-form threads (formed after heat-treat for improved fatigue strength), exclusive nut-starter and bullet shape radius that all but eliminates cross-threading, shot-peening, special baked-on dry film lubricant (reduces possibility of galling and assures consistent clamp loads), and double magnaflux inspection.
The head design fits the registers of all popular hubs without grinding, and studs are available in 31 underhead lengths to provide you with the optimum thread engagement for your particular setup. The finest studs available!
