The new Traxxas center differential for the E-Revo and E-Maxx transmits power independently from the transmission to the front and rear differentials, ensuring a smooth power delivery. This is the perfect solution for putting power to the ground even under rough conditions and maximizing cornering speed. The center differential is sealed and can be adjusted for specific driving conditions by using different fluid viscosities. The Traxxas center differential fits directly into the transmission of the E-Revo and E-Maxx and is sold fully assembled and filled with 500k silicone fluid.
