When subjected to higher lift cams and increased spring rates the stock needle bearing cages have shown their weakness and failed in performance applications. (The stock LS rocker arm from GM is very lightweight and works very well in the stock applications.)
VCM Performance are now introducing a new high strength trunnion with a premium proprietary bushing to replace the stock pieces for increased strength and added security for performance LS applications. Dedicated oil feel channels in multiple positions on the new trunnion provide a constant supply of oil to ensure proper and constant lubrication. Packed as a whole set to complete 1 x engine.
