Ultima’s 3.35” belt drive assembly revives the Old School drag race style primary drive at a new affordable price.

The Drag Race style unit with features like the out board bearing support, extra plate clutch assembly and Goodyear 85mm wide (3.35”) belts was designed to handle all the power you can throw at it.

If you need to keep some extra cash try out the street version which has all the same features without the added cost of the out board bearing support.

The Street units feature the same machining as the Drag Race Style so they can be upgraded with outboard supports anytime.
