7/16 12pt Stud Kit Bellhousing to Trans

The ARP 7/16 12pt Stud Kit Bellhousing to Trans (SKU: ARP100-0904) is a purpose-built fastening solution for engine-to-transmission connections in performance and racing applications. This four-piece stud kit features 7/16-14 threaded studs engineered to provide superior clamping force and reliability where factory hardware falls short. ARP studs and fasteners are widely recognized in the performance engine community for their ability to handle elevated pressures and vibration in modified engines.

Each stud measures 2.75 inches in length and is manufactured from chromoly steel with black oxide finish, providing corrosion resistance and durability in engine bay conditions. The kit includes matching 12-point nuts and washers, eliminating the need to source hardware separately. The 12-point nut design distributes load evenly across the fastener head, reducing the risk of galling or stripping compared to 6-point alternatives. Chromoly construction offers higher tensile strength than standard steel, critical for maintaining a secure seal under sustained boost or high rpm operation.

This bellhousing stud kit serves builders and enthusiasts upgrading engine combinations that exceed the limits of original equipment fasteners. High-horsepower engines, forced-induction setups, and drag racing applications all benefit from the improved clamping consistency ARP fasteners provide. Proper bellhousing fastening prevents slippage between engine and transmission during acceleration, protecting both components from misalignment and internal damage.

ARP fasteners are OEM-specified or recommended by many engine manufacturers and remain the preferred choice for professional engine builders and machine shops. Whether rebuilding a small-block Chevy, Ford, or Mopar engine, this stud kit provides the foundation for a secure, long-lasting assembly. The black oxide finish resists surface corrosion in damp engine compartments, and the complete kit format ensures nothing is forgotten during installation.
