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 Auto Racing Products (ARP) 12-Point Main Stud Kit is engineered for the serious engine builder. Specifically designed for Merlin II and III Big Block Chevy blocks, this kit features 12-point nuts that provide superior clearance and higher torque capacity compared to standard hex nuts. If you are pushing your engine to the edge, this is the hardware you need to keep your bottom end together.
The 12-point nut design is a favorite among professional engine builders because it allows for easier access in tight spaces and provides a cleaner, more professional look. More importantly, the 12-point design allows for higher torque settings without rounding off the fastener heads. By utilizing these studs, you ensure that the main caps are held with maximum clamping force, preventing the dreaded main cap walk that can destroy a high-performance engine. This kit includes everything you need to secure your main caps, providing the stability required for consistent performance at the track. Invest in the best for your engine build and experience the precision engineering provided by GGCRACING.
