• 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.
