So as i understand it a big wheel kit raises the axel up so im wandering if you you buy a rail extension that already has the big wheel kit incorporated into it. And if yes, where?

You can through most of the site that specialize in mountain stuff. You can also get the standard rails and get offset axles. Try highperformance engineering. Their web site is

Alright thanx alot

I think MMP or mountainmachinesperformance also carries the rail extensions with the raise built in for bigger wheels using the stock alxe or atleast used to. They carry offset axles for some models as well.
