You get one updated HEAVY DUTY drive shaft with clips,spacers,directions. The original driveshaft had cuts in it on each side of the track sprocket so that two clips could be slid on to it to hold the sprocket from moving left or right, But these machined cuts weakened the shaft and some people have bent there shaft so this is a stronger version without the cuts in it because it uses round spacers to hold the sprocket in place.
