GM LT1 / LT4 Rocker Arms w. BTR Premium Trunnion Kit Installed - Gen V LT

These BTR or GM replacement rocker arms with BTR trunnions installed are an easy alternative for customers who don't have rocker arms or don't have the tools required to install a trunnion kit in their factory rocker arms. Information about the trunnions used in these replacement rocker arms are as follows:

The TK002 trunnion builds on the success and knowledge we gained with our TK001. The TK002 features a trunnion with pre-installed inner race bearings. The TK001 trunnions 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 TK001 kits and many OEM applications. Additionally, these feature a self oiling axle with priority feeding to the trunnion itself.
