Ok so I'm too broke to buy an xo-1 right now so I've been purchasing parts to build one as I can afford it. While doing this I have my 4x4 slash torn apart for some new bearinngs a few upgrades and maint. I have noticed that the differential housings for the slash and the xo-1 are identical, so are the internal geers and bearings. The turnbuckles are the same as well. These parts are a lot cheaper for the slash so if you find yourself needing some of those parts for repairs look at getting the slash ones they are a lot cheaper.
not really cuz in the end the part numbers are still the same whether its the differential or turnbuckles or diffs and housings just gotta know where to look for them
