This is an optional SWorkz S350 12 Tooth S-System Pinion Gear. This gear provides an "under drive" gear ratio when used in the rear position, creating less rear end drive that allows the car to pull harder from the front. This is a great option for loose track conditions.
NOTE: This gear must be combined with the optional SWorkz 42T Crown Gear (SWX-330274) and is only compatible with SWorkz S350 vehicles equipped with the S-System drive train.
