Sputhe Softail Transmissions * are a superior replacement for the stock unit.  The gear ratios are the same as stock, except 1^st gear, which is slightly higher.  All gears, as well as the shift drum turn on needle bearings.  If replacement parts are ever needed, they are readily available from either Sputhe Engineering or your Harley dealer.

The case is cast in tough 356A-T6 aluminum, without the familiar OEM waffle pattern.  The Sputhe case contributes to both a cleaner exterior that better lends itself to polishing.  All components are American made.
