Races can be won or lost in the pits, so the engineers at ARP created the ultimate oval track competition wheel stud that facilitates quicker release/tightening of lug nuts and accurate wheel positioning.
A large number of NASCAR teams in Sprint Cup, Nationwide, and Camping World Truck Series use ARP's new Speed Studs (and companion Speed Nuts) exclusively because they are made from heat-treated 200,000 psi chrome moly steel.
They feature precision J-form threads, exclusive nut-starter, and bullet shape radius that nearly eliminates cross-threading, shot-peening, special baked-on dry film lubricant, and double magnaflux inspection.
A new head design fits the registers of all popular hubs without grinding, and studs are available in 31 underhead lengths for optimum thread engagement for your particular setup.
Speed Nuts are designed for professional racing environments where unbustable reliability is essential, and they feature a profiled nut face for easy installation and quicker socket releases.
Made from premium heat-treated chrome moly with a nominal rating of 200,000 psi tensile strength, they are shot-peened to remove stress risers and double magnafluxed after heat-treating and thread-forming to assure metallurgical integrity.
Coated with Alumotef III gold coating, Speed Nuts are ready for instant use.
