Team Associated have introduced a 46T ring gear for the T3 and T3e. The 46T ring gear is standard on the T3.1 and T3.1e, both of which come with V3 differentials. V3 differentials offer increased fluid capacity, more consistency over a run, and the ability to use HTC (High Torque Capacity) or LTC (Low Torque Capacity) internal gear sets. With this ring gear, racers using the previous generation T3 and T3e trucks may now upgrade to V3 differentials to take advantage of its benefits.
