Quite a few guys have switched to the 300EX with a spacer, other guys have asked me about the 400EX axle but I've never tried to install one. They use the same bearing, so it fits in the carrier. The 400EX axle will be too wide in some respects but I'm not sure what it takes to make one work. I'm fairly sure the 400EX sprocket hub bolts right on to the 350X.
All our government does is distract us while they steal from us, misspend our tax $ and ruin our country
