Where does it work....

[MetalMan]

Some quick speculation tells me it should fit in all Ofna Hyper series, Jammin cars/trucks, and Losi 1/8 should be fine. It likely won't fit in XTM stuff (XTM diffs are a tad longer), or the SH Z-Car (this buggy uses a shorter diff). Other than these, I dunno.

It won't fit in a Kyosho M9 either, it also uses a smaller diff.

Yep. Not a chance.

It should work in Mugen, AE, Xray (808 may requre raising the diff mounts since stock gearing is 42T,but any of the older ones and the XT8 No problem), Caster, Losi.
