ARP Speed Nuts

ARP Speed Nuts are designed for professional racing environments where split-second improvements in pit stop times can make the winning difference. 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. Coated with Alumotef III gold coatingthread-forming to assure 100% metallurgical integrity.
