The Performance Advantage of ARP Main Studs

Main studs offer a distinct advantage over bolts by providing a more accurate and consistent clamping load. By eliminating the twisting motion inherent with bolts during tightening, studs allow for a truer torque reading, which translates to a more uniform distribution of force across the main caps. This stability is vital for preventing crankshaft flex and maintaining optimal bearing life, making ARP main studs a cornerstone of a reliable high-performance BBC engine.
