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. ARP’s new “Speed Studs” (and companion “Speed Nuts”) are so good that a large number of NASCAR teams in Sprint Cup, Nationwide and Camping World Truck series use them exclusively.
ARP Speed Studs 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.
