ARP manufactures fasteners from premium materials including 8740 chrome moly, ARP2000, L19, Custom Age 625 Plus and other specialist alloys. The correct material depends on the fastener location, clamp load requirement, fatigue life, corrosion resistance and intended use.
ARP kits are engineered for specific engines and fastener locations, including head studs, main studs, rod bolts, flywheel bolts, balancer bolts and accessory hardware.
ARP offers multiple material levels depending on the application, from 8740 chrome moly through to ARP2000, L19 and advanced super-alloy fasteners.
When installed correctly with the specified lubricant, torque sequence or stretch procedure, ARP fasteners help maintain reliable clamping force under load.
The best ARP fastener is not always the one with the highest tensile strength. The correct choice depends on the engine, fastener location, cylinder pressure, RPM, power level, material, installation procedure and whether the application is street, race, marine or endurance use.
Start with the engine family and the fastener location. Head studs, main studs, rod bolts and head bolts all have different requirements and should be selected using the correct ARP application listing.
Confirm thread size, under-head length, grip length, washer requirement, material and torque or stretch procedure before ordering bulk ARP fasteners.
Do not guess critical engine fasteners. If you are unsure which ARP part number suits your application, contact Performance Fasteners Australia with your engine, vehicle, existing fastener details and intended use.
ARP stands for Automotive Racing Products. ARP manufactures high-performance automotive fasteners for engine, driveline, wheel, accessory and motorsport applications.
ARP fasteners are purpose-built for performance applications where material quality, fatigue resistance, clamp load and correct installation are important. Generic hardware should not be treated as equivalent to an application-specific ARP kit.
It depends on the engine and application. Head studs are commonly chosen for high-performance, boosted or race applications where improved clamp load and serviceability are important. Head bolts may be suitable for other builds where the ARP application listing recommends them.
Many ARP torque specifications are based on the use of ARP Ultra-Torque fastener assembly lubricant. Changing lubricant can change the clamp load achieved at the same torque value.
Always follow the instructions supplied with the specific ARP kit. General torque tables are useful for reference, but kit-specific instructions override general recommendations.
Yes. Provide your engine, vehicle, fastener type, current part number if known, and intended use. Performance Fasteners Australia can help identify the correct ARP fastener for your application.
Performance Fasteners Australia supplies ARP fasteners for street, race, marine, diesel, drag, circuit and high-performance engine applications. If you are unsure which ARP kit or bulk fastener suits your build, contact PFA with your application details.
