Package Type: Skin. Because races can be won or lost in the pits, the engineers at ARP set about to create the ultimate oval track competition Lug stud that facilitates accurate Lug positioning and quicker release/tightening of lug nuts. Designed for professional racing environments where splitsecond improvements in pit stop times can make the winning difference, and "unbustable" reliability is an absolute must. ARP’s Speed Nuts feature a profiled nut face for easy installation, quicker socket releases and resistance to jamming. They’re made from premium heat-treated chrome moly that’s nominally rated at 200,000 psi tensile strength, shot-peened to remove stress risers and double magnafluxed after heat-treating and thread-forming to assure 100% metallurgical integrity. Coated with Alumotef III gold coating. Speed Nuts are ready for "instant" use (thread chasing not required).
