Replacement Trunnion Kit for LS Engines Micro-polished hardened shafts with C932 bearing bronze bushings No small parts to come loose and damage your engine! Less prone to failure and loads are spread over a wider area! Oil channels keep the rocker arm lubricated LS GM BUSHING TRUNNION KITS These new bushing style LS GM trunnion kits for factory LS rocker arms are now available. The bushing design provides superior lubrication to the trunnion while also providing maximum load capability. Our innovative design prevents premature failures caused by the weak O.E. or replacement needle bearings, eliminating the possibility of debris from a bearing failure that can cause severe engine damage. Our special C932 bushing material is bathed in oil via grooves at 2 different locations on the trunnion. These channels constantly feed oil to the bushing surface ensuring proper lubrication. The greater surface of our bushed trunnion will support 300 times more load than a needle bearing trunnion. Our bushing gets more lubrication and has less load applied to it than the bushing in the small end of a connecting rod, giving it long service life.
