Traxxas 9554X Stub Axles Hardened Steel E10 Parts Cooling Fan: YesHardened steel stub axles. Two per package. The stub axle transmits drive from the driveshaft to the wheel hub and takes torsional load every time you get on the throttle. Hardened steel resists the twisting and splining wear that develops on a 6S truck, where a soft axle eventually rounds off and starts slipping under power. Important: Traxxas specifies these for use only with the #9557 driveshaft. Fits: Traxxas Sledge (95096 4). Direct replacement
