About ARP

ARP are a manufacturer of fasteners/bolts found in engines and drivelines, ranging from OEM replacement parts to specialty hardware for racing applications. ARP is the world leader in fastener technology. These range from quality high performance OEM replacement parts to exotic specialty hardware for Formula 1, IndyCar, NASCAR and NHRA drag racing and marine applications.

In order to ensure optimum quality control, ARP has grown to be exceptionally self-reliant and now controls all aspects of the manufacturing process. All operations are performed in-house and closely monitored. This is how ARP has been able to establish a reputation for “zero defects” quality throughout the industry.

FLYWHEEL BOLT KITS

ARP flywheel bolt kits, built for high-performance applications, offer exceptional strength and reliability. The Pro Series (200,000 psi) and High Performance Series (180,000 psi) feature heat-treated designs for improved durability. Both include washers and nuts for a secure, precise fit in demanding conditions.

WHEEL STUD KIT

ARP’s wheel stud kits are engineered for enhanced durability and performance, featuring heat-treated 8740 chrome moly steel with a tensile strength of 200,000 psi. These studs are cadmium plated for added corrosion resistance and are available in packs of four or five.

ARP KIT INSTRUCTIONS

Following ARP’s installation instructions is crucial to ensure optimal performance and safety. Proper installation guarantees that fasteners achieve the correct preload, preventing issues like component failure or engine damage. ARP provides detailed instructions and torque values for their products, accessible through their website, to assist users in achieving precise installation.
