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 bottom end of your Ford 302 is the foundation of your engine's power. To prevent main cap walk and ensure bottom-end stability under high-RPM stress, the ARP Main Stud Kit with Girdle is an essential upgrade. This kit provides the clamping force needed to keep your main caps secure, while the included girdle adds an extra layer of structural reinforcement to the main bearing area, significantly reducing block flex.
When you increase the power output of your Ford Small Block, the stock main bolts can become a weak point. By switching to ARP main studs, you gain the ability to achieve a more consistent and higher clamping force, which is vital for maintaining bearing clearances and preventing catastrophic engine failure. The addition of a girdle ties the main caps together, creating a rigid structure that can withstand the forces of aggressive racing. Each stud is heat-treated and black oxide finished for maximum durability in the harshest conditions. Whether you are building a street-strip machine or a dedicated track car, this kit is a must-have for any serious engine builder looking for peace of mind. Trust your bottom end to the industry-leading technology of ARP. Find all the components you need for your engine build at GGCRACING.
