This new Summit Racing Retrofit Rocker Trunnion Kit for GM LS engines is sure to appeal. If you add a higher lift camshaft and corresponding valve springs to an LS engine you’re looking for trouble; problems trouble with the needle bearings in the factory rocker arm trunnions, primarily.

Those bearings are not designed to take the hammering bigger cams and stiffer valve springs dish out. That leads to their premature demise.

Summit Racing’s 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 kit includes 16 trunnions, 32 bronze bushings, and 32 retainer clips. They fit all LS engines.
