This is an optional Kyosho 110mm HD Cap C-Universal Rear/Center CVD Set, and is intended for use with the Kyosho MP9 family of vehicles. Machined from high grade steel, these HD CVD's are designed to last and feature a cap that slides over the coupler to help prevent the pin from coming out if the set screw loosens up. CVD's help to improve the smoothness of the drive train as well as increase efficiency when compared to the stock universals or dog bone type driveshafts, and are the preferred driveshaft on smooth, high bite surfaces. Package includes one 110mm driveshaft, one coupler, one coupler cap and necessary hardware.
