If your going to keep the sled for another season and plan on doing alot of miles I would buy a titanium drive shaft from Mountain Performance. I think they cost around $400.00.

From what I have read, titanium would not be the best long term axle material. A 4340 steel alloy would be best... There are some posts around about a micro alloy replacement offered by someone..

micro belmont makes one out of what they call mirco-loy very strong.

How tight are you running the track tension? There are not a lot of broken drive shafts being reported.

I think I paid about $175 plus shipping for their drive shaft. Call Gary he is great to deal with. I broke my stock one at 8,900 miles. I have about 3,400 on Micro Belmont's and so far so good.
