Is there any difference between a 90 and 110 rear axle?

[crnacnac]

I'm doing another 70 project (CR80 powered) Does anyone know if there is any difference between a Honda ATC90 and 110 rear axle? Are the lenghts the same is the main concern. Any help would be appreciated. Thanks.

The early model us90 axle, 70-74 won't work, the splines are way different and the rear was meant to be unbolted so the us90 could fit into the trunk of a car. From 75-82 the rear axles are pretty much the same. 83-85 axles there is something different, I think it is the axle width. All the axles after 74 will take the different hubs, 3x100, hub for the 4 bolt 110 or will take the rear hubs from a 350x, 200x, 250r, style hub.

the 350x is too big, i know this from trying. It just spins on the Axel. The 200x I know works but not sure about the 250r

250r has the bigger spline like a 350x

200x 250x are both 24 spline and will work
