Default Difference in axles? 1/12th

I need a new axle for my Xray X11 and Xray offers 2 options, an aluminum and a fiberglass rear axle. Is there a difference between the two that is more underlying than just the material? Is one better than the other? Its about 2$ more for the fiberglass vs aluminum one.

I'll be testing this next week. The aluminum is lighter, truer, and more rigid. I don't believe it will stand up to much abuse. Price should be identical.

If you have to buy a Xray axle, get the fiberglass one. The aluminum one can get bent in a crash.

Not sure if the hubs are the right width (most likely they are), but do yourself a favor and get an IRS axle. I've used them in AE, CRC, and Serpent chassis without issue.

problem with running an irs axle is that the hubs maynot mesh up correctly and then you have all standard parts on a metric car. also the ring on an xray axle has no index like the irs axle.

The price for the IRS axle is a complete set, including the hubs for both sides, diff rings, etc.

The Xray cost is just the axle.

i would not go with the alum axle. there is no need for it. the part came out because of a bad run of graphite axles.
