#75179 - ALUMINUM INPUT SHAFT SET (FRONT AND REAR/PURPLE)
PRO 4/Machined Aluminum/Rear combines input shaft and spur adapter
Pro 4 front and rear input shafts made from precision machined purple anodized Aluminium alloy. The lighter Aluminium (savings of 6 grams of critical drivetrain weight) gives less rotating mass and therefore better acceleration and throttle response. The rear input shaft and the spur gear adapter are now one piece. This reduces wear and gives a more precise fit of the spur gear which increases the overall drive train efficiency.
This is a high performance upgrade for serious racers. Included in the set is a lightweight aluminum input shaft that replaces the stock front steel input shaft. Also included is a single-piece aluminum rear input shaft that replaces the steel input shaft and spur gear adaptor.
