The 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.
