ARP Speed Nuts 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. ARP Speed Nuts are 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% metallurgical integrity. Coated with Alumotef III gold coating. Speed Nuts are ready for “instant” use (thread chasing not required).
