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 pushing your Mazda 2.3L DOHC 16V engine to its limits, standard main bolts often fail to provide the clamping force necessary to prevent block distortion. This Auto Racing Products (ARP) main stud kit is the industry standard for high-performance engine builds, ensuring your main caps remain perfectly aligned under extreme stress.
By utilizing studs instead of bolts, you achieve more consistent torque readings and superior clamping force. The studs allow for easier engine assembly and prevent thread wear in the engine block, making them a must-have for any forced induction or high-RPM build. These studs are heat-treated to provide maximum tensile strength, ensuring your bottom end stays together when it matters most. Find the best engine fastener solutions for your project at GGCRACING.
