When racing professionals in NHRA, IHRA, NASCAR, and Formula 1 competition need bullet-proof fasteners for their high-performance machines, they turn to one company: ARP. Since 1968, Automotive Racing Products has been engineering and perfecting bolts, studs, nuts, and other fasteners for engines, cylinder heads, headers, wheels, transmissions, and more. ARP uses only top-quality materials—far above the usual “aerospace quality” others settle for—in a highly exacting manufacturing process to create fasteners with the strength and durability to last race after race.
