MRX6X = IFMAR World Champion Mugen Seiki is proud to introduce the new MRX6X 1/8th nitro on-road kit.Ê The MRX6X is inspired and based off the products used by Mugen Seiki driver,Shoki Takahata, to capture the 2019 IFMAR 1:8 On-Road World Champion hosted by Steel City R/C Speedway. The features of the MRX6X help improve steering, rear traction, drivetrain efficiency, and drivability. Features of the new MRX6X kit (H2008) includes: New front suspension geometry.Ê The new front uprights and aluminum bearing holders give you more overall steering and have a more precise steering feel.Ê The shape of the upper front arm also changed to accommodate the current bodies on the market. The new front shock tower and lower shock mounts have new geometry that increase steering in the middle to the exit of the turn.Ê New rear suspension geometry.Ê The new rear upper A-arms and rear upper arm plate help improve rear traction.Ê 0.8M pinion & spur gear.Ê The new 0.8M pinion and spur gear will increase drivetrain efficiency.Ê YouÕll notice increased acceleration and increased runtime. New roll bar for easier refueling.Ê This will allow quicker pit stops.Ê New front drive shaft.Ê The new front drives shafts allow increase steering angles and more overall steering.Ê Ê The front wheel lever (H2231) and rear wheel lever (H2232) are standard equipment on the MRX6X and allow easier installing/removing of wheels.

Front suspension improvements. New front suspension geometry includes new front uprights and aluminum-bearing holders give you more overall steering and have a more precise steering feel. The main difference in geometry with the front uprights is the axle height. The new axle height has better steering response and allows drivers to maintain good lap times even when over driving the vehicle. The aluminum-bearing holders allow you to adjust the axle from inline to 1mm of trail in relationship to the pivot balls. The aluminum inserts also allow the bearings to have more support and run more freely and it makes for easier maintenance.Ê The drive shafts can be removed with just two screws. The new shock mounts allow more clearance from the rim from touching the lower shock balls. The shape of the upper front arm also changed to accommodate the current bodies on the market. The new front shock tower and lower shock mounts have new geometry that increase steering in the middle to the exit of the turn. New front drive shaft allows increase steering angles and more overall steering.The front wheel lever (H2231) is standard on the MRX6X and allows easier installing/removing wheels. Rear suspension improvements. New rear suspension geometry includes new rear upper A-arms and rear upper arm plate help improve rear traction.Ê Drivers have the option between the upper A-Arm which give more rear traction and the upper I-arms that increase rotation.The rear wheel lever (H2232) is standard equipment on the MRX6X and allow easier installing/removing wheels 0.8 pinion & spur gears. 0.8M pinion & spur gear.Ê The new 0.8M pinions and spur gears use a finer pitch that will increase drivetrain efficiency.Ê On track youÕll notice increased acceleration as well as increased runtime.Ê With the 0.8M gears we did lots of testing because we noticed several brands having reliability issues when making the switch to 0.8M.Ê Our testing has provided amazing results in both performance and reliability even in extremely high grip conditions.Ê Also the life of the pinions has improved a lot.
