This is an optional JConcepts MBX7 4.0mm Carbon Fiber Rear Shock Tower. The JConcepts team went to work in the design lab, with a goal to better outfit and shed some weight from the World Champion Mugen MBX7. The design team has pin-pointed the exact geometry locations of the stock front shock tower, and developed a durable and lightweight option part that is a direct bolt-on for the popular Mugen buggy. The rear shock tower is 4mm thick and features all the stock mounting geometry in a more compact package. Reinforcement ribs have been added where needed for additional strength. Features:
