BBC Main Stud Kit - Fits 2-Bolt- No Windage Tray

The ARP BBC Main Stud Kit - Fits 2-Bolt is designed for serious big-block Chevy engine builders. This kit is crucial for those assembling engines that require reliable crankshaft retention, whether for street performance or competitive racing. Main studs are essential to prevent catastrophic crankshaft failure under load, making this kit a valuable addition to any engine build.

Engineered specifically for 2-bolt main blocks, the kit features ARP's proprietary 8740 chromoly alloy studs, which offer superior tensile strength and fatigue resistance compared to factory cast-iron bolts. The precision-rolled threads minimize stress risers, while the included hardened washers and nuts ensure uniform torque distribution across all main cap journals. This design helps reduce flex and vibration at the block-to-crankshaft interface, enhancing overall engine performance.

Builders and machine shops trust ARP for their critical fastening solutions, especially in applications where reliability is paramount. While this kit is particularly beneficial for high-performance builds, it is essential to assess compatibility with specific engine configurations, especially for those pushing beyond 500 horsepower. The ARP BBC Main Stud Kit is a reliable choice for those looking to enhance their engine's performance and durability.
