Brian Tooley Racing BTR TK002 V2 Rocker Arm Trunion Upgrade Kit for 1999-2013 Chevrolet Gen III IV LS1 LS2 LS3

BTR TRUNNION KIT - V2 - TK002 FOR LS1 LS3 1999 - 2013 LS TRUCK STYLE ROCKERS The all new Trunnion Kit V2 features a Trunnion with pre-installed inner race bearings. The V1 kits have stood up to an enormous amount of abuse, but we decided to upgrade them to a pressed inner race comprised of 52100 Heat Treated Bearing Steel, over the more commonly used 8620 Carburized Steel found in our V1 kits and many OEM applications. Additionally, these feature a self oiling axle with priority feeding to the Trunnion itself.
