Mugen concentrated on the making the suspension on the MBX7R ECO even better
with new 16mm bodied front and rear racing shocks. These bigger bore shocks will
improves stability in bumps which will handle all the power that this electric
buggy will produce. The 7R ECO chassis has been changed to increase strength and
give the ECO buggy a better feeling on all indoor and outdoor racing surfaces.
The 7R ECO has a re-designed front hub carrier in which the position of the
front axle has been changed to a trailing axle position. This new front hub
carrier in conjunction with a new designed steering ackerman plate will greatly
improve steering input of the 7R ECO. The front upper suspension arms have been
shortened 1.6mm to allow for more camber adjustability. The front and rear drive
train (diffs to wheels) have been changed and improved with new designed
universal drive shafts. These drive shafts will greatly improve the feel of the
ECO buggy on bumpy surfaces. The use of the universals will make the overall
drive train much smoother and will spin with less friction. The new wing mounts
will allow the wing to be moved closer to the shock tower and will increase rear
traction and jumping abilities.
The MBX7R ECO is equipped with a specially designed battery tray which will
accept either 2-2 cell LiPo batteries in a staggered mounting position for
optimum weight distribution or a single 4 cell battery location...the choice is
yours! A specially designed motor mount which has been beefed up so you can run
bigger and fast electric motors without losing gear mesh or without the flex
which causes motor or mount breakages. There is a heavy duty sliding motor mount
that is anchored down with 4mm screws for extra strength.

New parts on the MBX7R ECO
- E2129 Front Upright -
A new designed front hub carrier that incorporates the front universal to be in
a trailing axle position. A new universal (E2218) is used with this hub and it
uses an 8mm x 16mm ball bearing.
- E2131 Rear Upright -
The rear hub carrier has been modified to allow for use of an 8mm x 16mm ball
bear which is required for the new (E2219) universal shaft. This hub carrier
will also allow the use of the 15mm x 21mm ball bearing too. This hub carrier
can be used for either the MBX7R or MBX7.
- E2132 Front Upper Arm -
The front upper suspension arm has been shorten 1.6mm. This will allow the use
of the E0161 spacer between the pillar ball and the upper arm. This will allow
for the same camber on each side of the buggy.
- E2133 Rear Lower Arm -
The suspension arm has been modified to allow for clearance so the new E2219
universal doesn’t rub the arm. This arm will work on either the MBX7R ECO or
- E2218 Front Universal Shaft -
A new design universal drive shaft set for the front of the MBX7R ECO. The E2129
front upright must be used with these universals as they require an 8mm x 16mm
ball bearing. The length of the drive shaft is 91.5mm.
- E2219 Rear Universal Shaft -
A new design universal drive shaft set for the rear of the MBX7R ECO. The E2131
rear upright must be used with these universals as they require an 8mm x 16mm
ball bearing. The length of the drive shaft is 89.5mm.
- E2314 Steering Plate -
The new steering ackerman plate has 5 adjustment holes for maximum steering
- E2408 Wing Stay -
A new wing mount that can move the wing forward maximum 10.5mm to improve
traction and overall feeling of the buggy.
- E2409 Stone Guard -
The sides of the stone guard are changed to fit the new chassis.
- E2411 Chassis -
The side angle of the chassis has been changed to increase chassis strength.
This will allow for a better feeling on all surfaces.
- E2528 Front 16mm Shock Set
- E2529 Rear 16mm Shock Set -
New 16mm Front/Rear shocks which will greatly improve stability in bumps and
