XRAY have introduced the new graphite composite narrow gearbox for the XB2C. This gears gearbox is made from premium composite material accommodates 3 gears. The graphite molded gear box is lighter and stronger, with a narrower design to fit the narrower suspension holders, decreasing roll while increasing traction. All parts fit together perfectly, and give super-easy access to the rear differential. The durable gear box houses the differential and rear transmission, allowing the mounting of the rear roll center holder, motor plate, and rear shock tower.
