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.
