Trunnion Kits- Captured Bearing Style
8620 Alloy Steel
This rocker arm trunnion upgrade kit is a necessity when building any performance LS engine using the stock rocker body. Performance applications can stress the factory powdered metal trunnion & cage-less bearings causing loose needles to spread throughout the engine resulting in even more failure! Our upgrade kit include precision made 8620 alloy steel trunnions, captured roller bearings (the same bearings that power the NASCAR LS SPEC Engines), and high quality snap rings to ensure durable performance.
