Bellhousing Stud Kit w/ 1/4 Spacer

The ARP Bellhousing Stud Kit with 1/4 Spacer (Part No. 245-0202) is designed for builders and mechanics focused on high-performance engine-to-transmission assemblies. This kit addresses a critical weak point in drivetrain architecture, specifically at the bellhousing interface where the engine and transmission meet. It is ideal for those working on modified street engines, dedicated track platforms, or reinforcing factory assemblies.

Manufactured from premium-grade chromoly steel, ARP studs undergo a proprietary heat-treat process that enhances tensile strength and fatigue resistance, making them superior to standard fasteners. The included 1/4 inch spacer accommodates specific bellhousing geometries, ensuring proper stud engagement depth and effective load distribution across the clamping surface. This design minimizes concentrated stress at the threads, which is crucial for maintaining integrity under load.

This kit is particularly beneficial for bracket racers, engine builders, and automotive enthusiasts upgrading factory fasteners in both big-block and small-block applications. It is suitable for use in performance applications, including turbocharged and supercharged engines, where reliability and strength are paramount. The pre-sized studs also help eliminate guesswork during assembly, reducing the risk of cross-threading or inadequate preload.
