CNC-machined 84mm CVD drive shaft with 2.5mm pin created from world-renowned HUDY Spring metal. The drive shafts are of the worlds thinnest yet many durable drive shafts used in electric off road cars. Hardened with a proprietary solidifying procedure, the drive shafts provide unbeatable lifespan and reliability. The CVD set up in addition features a composite security collar that eliminates the approval associated with the drive shaft and stops the drive pin from getting free.
