Shimpo RK2 drive ring replica, 4.75 inches

This is a replica of an original Shimpo RK2 drive ring. It is cast in industrial urethane rubber. Total exterior diameter is 4 3/4 inches, total interior diameter of 3 5/8 inches.

Each ring is hand cast in an artisinal fashion in the Appalachian foothills.

If your original shimpo drive ring is very worn, you may need to adjust the motor mounting bolts on your wheel to compensate for the thickness of a new drive ring. Please contact a professional equipment repair person if you need help with this.
