6xl or 8xl

I've looked at those many times and wondered the same thing. They are for the original emaxx, not a 3.3spec or the newer 3906 model, but assuming you have an older emaxx, there is no reason why they wont holdup. They look like better made versions of the RC4WD punishershafts, only for an Emaxx.
