The shaft-driven 4WD TT-02B buggy chassis uses a skid-shaped frame. Its suspension setup uses 4-wheel independent double wishbone suspension with long arms, plus CVA shock units, giving the car assured handling, while Left/Right suspension arms and uprights are identical to facilitate hassle-free assembly. Front/Rear gearboxes include 4-bevel differentials for smooth operation, and are sealed to ensure that dust can't get inside. The top can be removed simply by loosening a few screws, making maintenance a breeze. 4 different gear ratios can be applied with the use of 3 separately-sold types of pinion gears, allowing you to match the characteristics of your car setup to the conditions at any given time. Of course, this off-road chassis also includes receiver case and motor cover to protect them from dirt and debris thrown up off of the track.
