Yok Y2-500A, Alum. Ball Diff Kit
A set of ball differentials that can be used on all YD-2 series cars.
The left and right differential housings are made of aluminum for a lightweight finish. While taking advantage of the high traction peculiar to ball diff, there are many merits such as improved throttle response due to its light weight, reduced gyro effect and improved exercise performance.
In order to minimize the wear of aluminum parts, a resin protector is attached to the tip of the dog bone of the universal shaft, which optimizes clearance and further enhances response.
