Molded composite engine gear box produced from premium composite product. Narrower design to suit the narrower suspension system holders, decreasing roll while increasing traction. The lightweight, tiny gear field has an internal design to accommodate a 3-gear setup for right-side engine position. All components fit completely together, and present super-easy use of a corner differential. The durable gear field houses the differential and back transmission, allowing the mounting for the back roll center holder, motor dish, and rear shock tower.
