Rocker Arm Stud Pinning Kit

The MR. GASKET Rocker Arm Stud Pinning Kit (SKU MRG806G) is a specialized engine assembly tool designed to secure rocker arm studs during high-performance engine builds and machine work. This universal kit includes precision drill bit and pins, enabling technicians to accurately align and lock rocker studs in position before final torquing, preventing unintended movement during critical assembly phases.

The pinning method provides temporary positive location of studs while performing valve train setup and cylinder head work. By drilling through pre-positioned holes and inserting the included pins, technicians eliminate the risk of stud drift or misalignment that can compromise valve clearances and pushrod geometry. This approach is particularly valuable when working with tight tolerances on performance engines where precision assembly translates directly to reliable operation and consistent valve timing.

Intended for engine builders, machine shops, and serious enthusiasts performing rocker arm stud installation on small-block and big-block applications, this kit fits universally across multiple engine platforms. MR. GASKET's rocker stud pinning kit is a cost-effective addition to any engine assembly toolkit, reducing potential rework and ensuring accurate valve train geometry from the first assembly pass.

This compact tool weighs just 0.08 lbs and stores easily alongside other engine assembly supplies. The included drill bit and pins are engineered for precise fit and repeated use across multiple engine builds, making it a reliable reference for rocker stud alignment work.
