Must use long drive with 3rd bearing support
For use on Sport & X-Ped Go-Peds. 2.875 inch total length. You will need to use your stock 6x45mm spindle bolt(not included).
Stock Sport spindle size is 0.625" diameter. Larger diameter spindle equals more top speed(to a point), but with slower acceleration. Too large of a spindle on a stock engine with a heavier rider will result in slow acceleration and slower top speed. Engine mods and rider weight have a big effect on spindle size.
