Automotive Racing Products (ARP) high-strength fasteners — head studs, bolts, and kits engineered for reliability in performance and racing engines.
ARP manufactures premium high-strength fasteners including head studs, main studs, rod bolts, flywheel bolts, and complete engine bolt kits trusted in performance, racing, and rebuild applications worldwide.
ARP head studs provide more consistent clamping force than factory bolts, improving head gasket sealing and reliability under high cylinder pressures, which is essential for boosted or high-compression performance engines.
Many ARP fasteners are reusable when properly lubricated with ARP assembly lubricant and torqued to specification, though critical rod bolts should be inspected and replaced according to manufacturer guidelines.
ARP offers head stud kits, main stud kits, rod bolt sets, intake and header bolt kits, flexplate and harmonic balancer bolts, and accessory fasteners for most popular engine families.
