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.
Kit includes the trunnion, bushings and C-Clips and can be used with the stock rocker bolt
