ARP (Automotive Racing Products) makes the strongest fasteners in motorsport — head studs, main studs, rod bolts, and flexplate bolts used by every Formula 1, NHRA, NASCAR, and championship motorsport program. Aerospace-grade alloys, exact-fit machining.
Maximize the strength and reliability of your Acura B18A1/B1 B-Series engine with the Auto Racing Products (ARP) 208-5404 Main Stud Kit. This essential upgrade replaces the weaker OEM main bolts with high-strength chromoly studs, providing a significant increase in clamping force. Crucial for any performance build, these studs prevent main cap movement and maintain precise bearing clearances, even under the most demanding conditions.
Each ARP main stud is meticulously crafted from a proprietary chromoly steel alloy, then heat-treated to achieve optimal tensile strength and durability. The threads are rolled after heat-treatment, a superior manufacturing process that significantly improves fatigue life compared to cut threads. This ensures a more robust and long-lasting fastener. The black oxide finish not only provides excellent corrosion resistance but also gives a professional, high-performance aesthetic.
The 12-point nuts included in this kit allow for accurate and consistent torque application, which is vital for maintaining proper crankshaft alignment and preventing main cap walk. By upgrading to ARP main studs, you dramatically enhance the rigidity of your engine's bottom end, reducing the risk of catastrophic failure in high-horsepower or high-RPM applications. This 208-5404 kit is an indispensable component for anyone building a reliable, high-performance Acura B18A1/B1 engine.
