Make Your Rockers Last Longer with a Summit Racing™ Retrofit Rocker Trunnion Kit for GM LS
Add a higher lift camshaft and corresponding valve springs to an LS engine and you’re looking for trouble—trouble with the needle bearings in the factory rocker arm trunnions, that is. Those bearings are not designed to take the hammering bigger cams and stiffer valve springs dish out. That leads to premature trunnion demise.
The Summit Racing™ Retrofit Trunnion Kit is the solution. The kit has hardened steel trunnions with bronze bushings that can handle loads many times greater than needle bearing trunnions. The design also ensures the trunnions get maximum lubrication to prevent galling and seizing.
The Summit Racing Retrofit Trunnion Kit includes 16 trunnions, 32 bronze bushings, and 32 retainer clips. They fit all LS engines.
