This left or right drive shaft is suitable for an early Renault R4 model. The shaft links the gearbox to the wheel hub and transfers engine torque to the wheels. Its design supports stable power transmission in straight driving and cornering. The length and splines match the original suspension and wheel carrier of this vehicle type. The shaft operates with constant velocity joints that allow movement at different steering angles and suspension travel. This component fits into a standard drive and brake system without modification and keeps the driving forces within the intended layout of the front axle.
