It is one size too big on the thread, the ls10 and crt.5 use a m4 thread (I think), the emaxx is m5 or larger. They make a killer flanged nut for the savage, but it is too big (thread size) but it will fit the emaxx axles.
These are for the Lightning GT10 to make the stock GT10 14mm hex wheel fit it. Its a stock item and a direct fit for the Lightning Staduim 10. Not sure about a 17mm adapter though. Just thought Id throw it out incase it helps.
EDIT: With these hexes stock Maxx 14mm wheels work perfectly. I used them all the time on my nitro GT10.
I can't decide if its more fun
to make it...
or break it...
