Bellhousing Stud Kit w/ 1/4 Spacer

The ARP Bellhousing Stud Kit with 1/4 Spacer (Part No. 245-0202) is a professional-grade fastener assembly engineered for high-performance engine builds where bellhousing attachment integrity is critical. Manufactured from chromoly steel and finished in black oxide for corrosion resistance, this kit delivers the precision and strength required in top fuel drag racing applications and other extreme-duty motorsports environments where thermal cycling and vibration loads demand uncompromising reliability.

The kit features 7/16-14 inch studs measuring 2.15 inches in length, sized to accommodate the included 1/4 inch spacer for proper bellhousing clearance and alignment. Each stud is paired with 12-point nuts and hardened washers, ensuring even load distribution and resistance to vibration loosening during sustained high-RPM operation. The 12-point nut design provides additional contact points compared to standard hex nuts, improving grip and reducing the likelihood of fastener rotation under extreme operating conditions. ARP's chromoly material selection and precision manufacturing tolerances make this kit suitable for motor plate applications in professional-grade engine bays.

This bellhousing stud kit is designed for builders and engine shops constructing competition drag racing engines, particularly those running top fuel configurations where every component must withstand repeated shock loads and elevated temperatures. The inclusion of the 1/4 inch spacer addresses a common fitment requirement in engine plate systems, eliminating the need for sourcing spacers separately. The complete fastener package—studs, nuts, washers, and spacer—simplifies assembly while guaranteeing compatibility across all components.
