Thank you for viewing! This is a counter shaft made with motor pins for the MA chassis. In the many races I've competed in, I've been helped by this shaft and have won many times! I made this because I want everyone to experience it! When you receive it, insert the colored side from the opposite side of the bearing. It is made to fit multiple center chassis, but there may be individual differences and scratches from the manufacturing process, so please refrain from purchasing if you are sensitive to these details. #Mini4WD #MSFlex #MachDashMotor #SprintDashMotor #FinishedProduct #CounterShaft #MAChassis #HyperDashMotor
