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.
Ensure your engine's bottom end remains secure under extreme stress with the Auto Racing Products Main Stud Kit. Designed specifically for the Buick 350 with 2-bolt mains, this kit replaces standard bolts with high-strength studs to provide consistent clamping force and prevent main cap walk. Whether you are building a street performer or a dedicated drag racer, these fasteners are essential for engine longevity.
Each stud is precision-machined and heat-treated to exceed OEM specifications, ensuring that your main caps stay perfectly aligned even during high-RPM operation. The use of studs instead of bolts also allows for more accurate torque readings, as the stud does not twist in the block during the tightening process. This kit is the gold standard for engine builders looking to eliminate potential failure points in their Buick small block builds. Trust the experts at GGCRACING to provide the high-performance hardware you need for your next engine project.
