The Super-Ass swingarm kit is for those that want to convert their Softail or Wide-Tail Softail to accept Avon's 230x15 Super Wide rear tire. This tire measures 250mm wide if fitted on an 8" wide rim. Kit bolts straight into both the stock Softail frame as well as the Zodiac WideTail frame. You can still use the final belt drive when used in a WideTail frame, a stock Softail must be converted to final chain drive or the late 20mm wide belt. When you use this narrow belt or a chain in a Zodiac WideTail frame you can easily go up to a 250 series tire.

The complete kit includes:
•Fully TIG welded swingarm with stainless fender extension plate
•Swingarm pivot
•Rear wheel axle with chrome nuts
•Crankshaft extension for 1986-1999 models
•Extended crankshaft nut for 1991-1999 models
•Primary spacer with O-ring and bolts
•Longer inner primary mounting bolts
•Primary gasket set
•Transmission off-set plate
•A complete new bracket and hardware kit for the 5th transmission mounting stud

Kits can also be used for 1987-1990 models if correct crankshaft extension, extended sprocket shaft nut and primary gaskets are used. Due to the wide variety of wheels,fenders, fender struts, and wheel spacers are not included,these can be found elsewhere in this catalog.
