These rockers come with your choice of trunnion kit installed:
The TK001 (V1) rocker trunnion is an excellent upgrade compared to the stock LS rocker trunnions. The TK001 utilizes high quality components to improve reliability and performance by eliminating the failure prone, limited travel factory bearings. The captured needle design of these bearings eliminates the possibility of them falling apart, sending needle bearings through the engine as the stock rockers are prone to do.
The TK002 (V2) trunnion builds on the success and knowledge gained with years of producing the popular TK001 kits. The TK001 trunnions have stood up to an enormous amount of abuse, but the TK002 takes durability a step further with the upgrade to a pressed-on inner bearing race comprised of 52100 heat treated bearing steel, over the more commonly used 8620 carburized steel found in the TK001 kits and many OEM applications. Additionally, these feature a self-oiling axle with priority feeding to the trunnion itself.
