These shafts are direct replacements for the output shaft of our Sport Gearboxes. They protrude 1, 2, or 3 inches from the face of the gearbox. They are great if you modified the original shaft and want to return them to stock, or if you need a different length shaft from the one that was ordered. To remove these shafts, you need to remove and reinstall a retaining ring inside the gearbox. If you need a spare ring they are available as am-2371.
