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.
