If your track is the original, a new 1.5 will make it seem like a different sled. That would be the cheapest route. A Camoplast Intense comes to mind.The sled runs awesome, just does terrible in powder over a foot in depth.
Big Bear where?
listen to these guys, they helped me out a lot with mine, i did slp rail extension to 136 with 1.5 track and mountain max front end sled goes places i didn't think it would, only thing i need to do is get a new shock for the rear and tighten the shit out of it so me and the wife can ride lol.
