ARP Fasteners Australia: Why Every Serious Engine Build Starts With ARP

In the world of performance engine building, the saying goes: your engine is only as strong as its weakest fastener. ARP - Automotive Racing Products - has been answering that challenge since 1968, and today they're the global gold standard for high-performance bolts, studs, and fasteners. BYE Performance stocks and uses ARP fasteners across our engine builds in Perth, and we'll explain why we'd never build a serious engine with anything less.

The ARP Story: From Backyard Garage to Global Standard

ARP was founded in 1968 by Gary Holzapfel, a fastener specialist with aerospace manufacturing experience who noticed that his friends' racing engines kept failing due to cheap hardware. He set out to create fasteners that could genuinely withstand the extreme temperatures, pressures, and vibrations of a high-performance engine. Over 50 years later, ARP employs hundreds of people across facilities totalling more than 200,000 square feet in Southern California, and their fasteners are used by professional racing teams across every major motorsport category in the world.

What Makes ARP Fasteners Different?

There are several key engineering advantages that separate ARP from standard hardware:

Aerospace-grade alloys - ARP uses proprietary materials including ARP2000 chromoly steel (tensile strength of 220,000 psi) and Custom Age 625+ (a nickel-based super alloy used in aerospace and nuclear applications). Standard grade 8 bolts typically offer around 150,000 psi tensile strength.

Thread rolling after heat treatment - Most manufacturers cut threads before heat treatment. ARP rolls threads after, which means the heat treatment strengthens the material between threads, resulting in dramatically improved fatigue resistance.

Precision manufacturing - ARP's tolerances are tighter than automotive standards, ensuring consistent clamping force across every fastener in a kit.

Corrosion protection - Black oxide finish, chrome, and stainless-steel options ensure the right level of corrosion resistance for each application.

The ARP Fastener Range: What's Available

ARP makes fasteners for virtually every point in an engine or drivetrain:

Head stud kits - The most popular product. ARP head studs create more uniform clamping force across the head gasket compared to bolts, which is essential under high boost pressure. Critical for any turbocharged build.

Main stud kits - Secure the main caps to the block, preventing cap walk under high RPM and power.

Rod bolt kits - The last line of defence between your connecting rods and an engine failure. ARP rod bolts are mandatory for any high-power build.

Flywheel and flexplate bolts - Prevent flywheel movement under power, important for high-horsepower builds.

Header and exhaust fasteners - Stainless steel, designed to handle extreme heat and resist galling when removing headers after time.

Accessory fasteners - Water pump, timing cover, valve cover, intake manifold, and more.

ARP for LS Engines: A Perfect Match

The LS engine family (LS1, LS2, LS3, LS7, LSA, L76, L98) is arguably the most popular performance platform in Australia, and ARP offers a comprehensive range of LS-specific fasteners. From head stud kits that handle the demands of a supercharged LS3 to rod bolts for a built stroker, ARP covers the complete LS fastener picture.
