2000 Summit 600 - 136' to 151"

136 t0 151

I streched my 2000 700 summit from a 136 to 159. Bought rail extentions from MMP and built my own tunnel extention out of diamond plate. I also put on rear drop brakets and a new bumper off a 03 summit w/159" track.

As far as drivers are concerned it depends on what track you are going to use? If you stay with the older ski doo tracks I believe all of them are the same pitch so you won't have to change out drivers. As for the cooler you won't have to change it either but you need to do the extension so you can get the snow up to your cooler and maybe just for the hell of it run scratches of some sort. If I was you I would look in to changing the gearing alittle bit to get some low end back for the bigger track. Then get a hold of Dyno Joe's clutch kit and hold on!!!!:scared: It will be like riding a whole new sled. So in summary you need track, rails and or extensions, tunnel extension, and gearing. Slp makes rail extensions and tunnel extensions I used them on mine and like them.

You would have to swap for a HPV secondary. Joe doesn't have kits for the Formula secondary.
