These new bushing LS trunnion kits for factory LS rockers are shipping mid February. Engineered to provide maximum lubrication to the trunion while also providing maximum load capabilities, the NEW bushing LS trunnion UP-grade kits give the LS world peace of mind. The proprietary bushing material is fed with an oil channel at the 10 and 2 positions of the trunion. This channel constantly feeds oil to the bushing surface ensuring proper lubrication. The greater surface area will support 300X the load of what a needle will. Also there is NO CHANCE of needle bearings destroying the engine when using much more aggressive cam profiles with stock type rockers.
