The Mugen MBX7R has several big improvements that makes it one of the best buggies ever made for 1/8 off-road nitro competition.
Mugen concentrated on the making the suspension on the MBX7R even better with new 16mm big bore front and rear racing shocks. These new shocks improve stability in bumps and on jumps. The bigger shock bodies will make the 7R have less fade during longer runs so you can drive even harder than ever before.
Rear End
The rear shocks are 4mm shorter along with the a new lower rear shock tower to keep the back of the 7R hooked up and on the ground. The 7R gets a new chassis plate with the side angle of the chassis changed which creates more strength and a better feel. New wings mount will allow the wing to be moved closer to the shock tower to allow for better traction and jumping abilities.
 Steering Knuckles
The MBX7R gets a re-designed front hub carrier with all new trailing axle design. This will improve overall steering and feeling of the 7R. A new steering ackerman plate with additional steering tie rod holes to have maximum steering adjust-ability. The front upper suspension arm has been shorten 1.6mm to allow for more camber adjust-ability and the use of the E0161 spacer between the pillar ball and upper arm.
The drive train of the MBX7R has been changed and improved with the use of a new universal style drive shaft for both the front and rear drive shafts. This will greatly improve the feel of the buggy on bumpy surfaces. The use of the universal will make the overall drive train much smoother and will spin with less friction.
Fuel Tank
The fuel tank gets a re-designed baffle system with a clunk pickup to improve fuel pickup and run time.
