Designed for professional racing environments where split-second 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 190,000 psi tensile strength, shot-peened to remove stress risers and double magnafluxed after heat-treating and thread-forming to assure 100 percent metallurgical integrity.

Coated with Alumotef III gold coating. Speed Nuts are ready for instant use (thread chasing not required).
