DNA Wheel Hub Spacers Don't Fit

I bought some DNA wheels off Craigs list, and can't seem to make the front work with any combination of spacers, which either the supplied ones, or with the factory ones.

The seller said these came off of a 2007 YZ450, and mine is a 2006 YZ450 so I'm assuming they are the same.

Has anyone had an issue similar to this?

I have an '08 yz450 with exact problem so I got more spacers sent out from DNA , which came about 10 months later and they were the same ones so now I'm having them custom made from a machinest. Truthfully these rims are crap.

Are they still using a crush tubes on those?

I bought one a few years ago not knowing they came with a stupid crush tube and custom size bearings. Woudn't fit on my bike (2006 YZ450) without using the stock spacers (which you cannot put in the wheel)

I called them and requested they make their hubs the same size as stock so you can replace the bearings yourself AND use the stock spacers.

I literally threw the whole wheel in the garbage! Brand new!

wait what the hell are crush tubes? if you don't mind me askin, cuz I've noticed the ends if the inner spacer are a weak aluminium cylinder that makes installing the wheel spacers a real chore

Crush Tubes are the aluminum sleeve that goes through the hub that DNA wheels use.

This is a scheme that high quality aftermarket modular hubs (as differentiated from DNA) use to allow them to build a single main hub with one set of bearings that can be fit to a broad range of applications by changing the center spacer and outer spacers. The center spacer is made with an ID the same size as the target axle, and with a machined step on each end to fit the bearings. Nothing wrong with the basic setup except that it complicates bearing replacement.

The aluminium used seems very weak and thin though and when axle is torqed seems to mushroom the end

That's because they didn't do it right. The steps on the center spacer should not extend beyond the bearing edge, and the bearing should be enough larger ID than the biggest axle they're used for to allow a reasonably thick walled step section. The material used has to be sturdy, too, obviously, but these are some of the things that get bypassed when the low cost option is chosen.
