The ultimate insurance policy against head gasket failure in high-performance engines. At Chicane Australia, we specialise in the fast supply of genuine ARP Head Stud Kits, specifically engineered for high-boost and high-compression applications. We facilitate rapid sourcing and nationwide delivery for the premier tiers of the ARP catalogue, ensuring your engine remains sealed under extreme cylinder pressures.
Technical Superiority & Premium Material Grades
Standard OEM head bolts are "torque-to-yield" fasteners designed to stretch, making them a significant weak point when power levels increase. ARP Head Studs provide a much higher clamping load and superior tensile strength, making them essential for any serious performance build. By utilising a stud rather than a bolt, you ensure a more accurate and even load across the head gasket while eliminating the twisting force (torsion) during assembly.
Our sourcing capabilities focus on ARP’s most resilient alloy grades: • ARP2000 Series: The industry standard for high-boost Nissan RB26, Toyota 2JZ, and Subaru EJ engines. Rated to a tensile strength of approximately 220,000 psi. • Custom Age 625+: The ultimate solution for elite-level builds. With a tensile strength of over 260,000 psi, these are designed for extreme motorsport applications where secondary head lifting is not an option.
Based on the Central Coast, NSW, we provide the technical expertise to ensure you receive the correct kit and torque specifications for your assembly. We work closely with our supply network to ensure your fasteners are sourced and despatched with speed.
ARP Head Studs FAQ
Why should I choose ARP2000 over factory bolts?
Factory bolts are designed for stock power levels and cannot be reused. ARP2000 studs are manufactured from a proprietary alloy that handles the extreme cylinder pressures of turbocharged engines, preventing head lift and gasket failure. They are also reusable, making them a better long-term investment.
When do I need to upgrade to Custom Age 625+?
If you are pushing extreme boost levels (typically 35psi+) or building a dedicated drag or circuit engine with very high cylinder pressures, Custom Age 625+ offers the highest tensile strength available. It is the best way to ensure maximum clamping force for elite builds.
How quickly can you supply these kits?
We utilise a robust Australian supply network to ensure fast turnaround. Most ARP2000 and Custom Age 625+ head stud kits are sourced and despatched within a few business days for nationwide delivery.
