Smith Brothers Chevy LS1 LS6 V8 Roller Rocker Arm Bronze Trunnion Bushing Upgrade Kit USA MadeLS Chevy trunnion kits for factory LS rocker. The bushing design provides superior lubrication to the trunnion while also providing maximum load capability. The innovative design prevents premature failures caused by the weak O.E. or replacement needle bearings, eliminating the possibility of debris from a needle bearing failure that can cause severe engine damage.
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 the bushed trunnion will support 300 times more load than a needle bearing trunnion. The 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.
Fits all LS Style Rocker Arms. LS1 LS2 LS3 LS6 LS7 LS9 LSX
