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.
The foundation of any high-performance engine is its bottom end. The Auto Racing Products (ARP) Main Stud Kit (208-5401) is designed to keep your main caps locked in place, preventing cap walk and ensuring precise bearing clearances under heavy loads. Specifically engineered for Honda 4-cylinder engines with 2-bolt mains, these studs provide significantly higher clamping force than standard OEM bolts.
By utilizing studs rather than bolts, you ensure that the main caps are seated consistently every time the engine is assembled. This kit is a critical upgrade for anyone performing a rebuild or increasing power output through turbocharging or high-RPM operation. The superior material properties of these ARP fasteners ensure that your crankshaft remains stable, protecting your investment from catastrophic failure. Trust your engine's internal integrity to the experts at GGCRACING.
