Longer axles per-say dont exist, but there are a variety of extensions, and diffeent style 17mmhub adaptors. Some just slide on like normal 14mm hexes do, where as others bolt onto the axles, making themn much more sturdy and less prone to wobble/slop.
Yeah I have the ones that slide down to the pin then you place the wheel on then it has another piece on the outside but it barely lets me thread on the nut. I mean it probably gets half way on. Do you have an adapter that you would suggest using cuz the one I got on pisses me off, lol
I did have them a while back shortly, but sold them off because I didnt like how narrow the Phaltlines are- 'fickle' is a good way to describe my choices sometimes....
As soon as the revo platinum is released traxxas should have factory 17mm hubs available. I have the ofna 17mm adapters now and they are pretty good, but I think the factory fit ones will eliminate some of the little sloppiness the ofnas have.
I've seen some 23mm hubs come with little axle spaces to take different diameter axles. I got some to use on a savage, then used the spaces to run the stock savage 17mm hexes on the revo. works like a charm.
