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.
When you are pushing your Nissan 2.5L RB25 engine to its limits, factory head bolts may not provide the clamping force required to keep your head gasket sealed under high boost or high-compression conditions. The Auto Racing Products (ARP) Head Stud Kit is the industry standard for engine builders worldwide. Manufactured from premium 8740 chromoly steel, these studs are heat-treated to provide superior tensile strength and consistent torque loading.
The 12-point nut design allows for easier access in tight engine bays and ensures that you can achieve accurate torque readings during assembly. By utilizing studs instead of bolts, you benefit from easier cylinder head installation and improved gasket alignment. This kit is the definitive choice for street-tuned, drift, and drag-racing RB25 builds. Protect your engine investment with the best fasteners on the market. Find this and other high-performance Nissan engine components at GGCRACING.
