STUD FOR 9017-4B 1.375

The STUD FOR 9017-4B 1.375 is a precision oil pump alignment stud engineered for Barnes 4-stage dirt late model engine pumps. This component serves as a critical fastening and alignment element, ensuring proper pump positioning during assembly and operation. Designed for racers and engine builders working with high-performance dirt late model platforms, this stud eliminates guesswork in pump setup and helps maintain consistent oil delivery under demanding racing conditions.

Manufactured from hardened steel in its natural finish, the STUD FOR 9017-4B 1.375 measures 1.375 inches in critical dimension with overall length of 9.75 inches, providing robust engagement and stability. The steel construction resists vibration loosening and thermal stress, essential in racing engines where pump alignment directly affects oil pressure consistency and engine longevity. This alignment stud integrates seamlessly with Barnes pump systems, functioning as both a mechanical locator and load-bearing fastener within the pump assembly architecture.

This stud is indispensable for late model dirt track competitors building or maintaining engines with Barnes 4-stage pump configurations. Engine builders and mechanics rely on this component during pump installation to guarantee proper alignment before final bolting, reducing the risk of pump cavitation, pressure loss, or misalignment wear. The lightweight design (0.13 lbs) minimizes rotating mass while the precision dimensions ensure compatibility with OEM pump housings. Individual stud purchase allows for replacement of worn or damaged originals without requiring complete pump assembly replacement.
