      Enhanced Valve Train Performance. The Comp Cams 1/2-Inch Rocker Stud and Trunnion Retro-Fit Kit significantly stiffens and stabilizes the valve train for SBC and BBC engines equipped with Ultra Pro Magnum™ or Ultra Pro Magnum™ XD rocker arms. It is designed to maximize valve motion and improve engine performance, particularly for competitive applications such as NHRA Stock Eliminator where stud girdles are prohibited. This kit provides a comprehensive solution to upgrade and rebuild existing rocker arms for increased durability and precision.

      Construction and Appearance. The kit features high-quality 1/2" ARP studs, replacement trunnions, polylocks, bearings, and snap rings engineered for strength and durability. Each component is manufactured to precise tolerances to ensure proper fit and function within the rocker arm assembly. The parts are finished with materials suitable for high-performance environments, providing both corrosion resistance and long-lasting wear.

      Installation. Installation requires moderate mechanical skill, with no drilling necessary as it is designed to retrofit existing Ultra Pro Magnum™ rocker arms. The kit comes complete with all necessary parts to facilitate a straightforward replacement and rebuild process.

      Warranty. This product includes a 12-month warranty against manufacturing defects.
