Mugen Seiki MBX8, more details & photos revealed


After unveiling the first details of the forthcoming MBX8, Mugen Seiki have released a second part with another details and photos. The MBX8 features new FF/FR/RF/RR suspension mounts and new front and rear gearbox. The new gearbox makes allows you to remove and service the differentials without detaching the suspension arm mounts allowing easy access to the front and rear differential.

The front and rear lower arms use a new impact resistant material for increased durability. The new arms are box-shaped and include arm stiffeners to reduce flex and increase durability. Adjusting the hardness of the lower suspension arms is now possible. This allows you to fine tune the steering and traction from track to track. CFRP plates will be released as an option part later.

The center differential mounts use a stiffer material and has a new top plate to reduce chassis flex and increases clutch bell, spur gear, and clutch bearing life. The reduced chassis flex also provides more consistent handling in all conditions. The top plate design also makes it easier to adjust the brakes and easier maintenance.


The MBX8 still uses a flat 2S lipo or Life battery, but the receiver battery is now enclosed in a molded battery box. The battery box allows for quick and easy access to the battery. The molded box also helps protect the battery from hard impacts. The battery box is mounted to an updated carbon fiber radio plate.

Also new or upgraded parts are the body, clamping servo saver nut, F/R shock towers, front bumper, front center and rear center universal joint. The Mugen MBX8 will be available late January 2018.
