ARP’ s motto has long been“ Working together we win races!” The company was founded in 1968 to help racers achieve greater reliability through developing superior quality fasteners that solved their problems. That premise holds true today, as ARP continues to develop fasteners for new engine combinations. For example, there are 50-some head stud kits for small block Chevy OEM and aftermarket packages. And a couple dozen more for LS / LT engine combinations— including some new ones for 2025.

You can get ARP’ s polished stainless steel or black oxide finished 8740 chrome moly fasteners in handy 5-packs by size that range from 1 / 2” diameter by 6” long down to the new # 8-32 12-point stainless bolts. They are nominally rated at 180,000 psi tensile strength and fully 20 % stronger than Grade 8 hardware.

“ Made in USA” is another tenet of ARP. All fasteners are manufactured in-house at the company’ s Southern California facilities to the industry’ s highest standards. From forging to heat-treating and final machining, all operations are carefully monitored to assure total quality control. ARP is a family owned and operated company, now in its 3rd generation, with the singular goal to produce the finest high performance fasteners on the market. This dedication has enabled ARP to become the world leader in racing fastener technology.
