I have an 06 summit X, I was wondering if somebody makes rail extensions for this or if its best to just buy 159 rails. Also who would make a good tunnel extension. Thanks
144" to a 159"

I did something similar. Extended my '06 from 144 to 162. Actually, the guy I bought it from had our shop do all the workj ust before he sold it to me. Used the RT1000 rear cooler, tunnel cap, and suspension rails. Wrapped a 162x16x2.5 CE on it with 9" CF wheels. The thing is amazing i nthe deep snow but the 144" could be so much more fun. I still have all the 144 parts minus the track. I'm actually thinking of going opposite to what your doing. But don't get me wrong, the 162 CE on this sled keeps it in front of every local XP except for a Split Second BigBore.

Just did the exact same thing with my '05. Put a 159x2.25x16 on. I used the 144 to 162 SLP tunnel extension, and Mountain Machine Performance rail extensions with the 8" big wheel kit. It works awesome. Have ridden the last few weekends on Mt. Adams and gone places I could never go before with the 144. I think the tunnel ext. was $150ish with shipping and the Rail exts. were around the same. Picked up the track from an '07 XRS for $240 shipped. Lots of people don't like that track b/c of trenching in bottomless powder, but that happens very rarely here. So far it has performed flawlessly. Haven't ridden in 4' of powder yet, but will have to be better than the 144. Hope this helps.

For a tunnel extension I used a ski-doo 159 one and riveted a chunck of aluminum that you have between the gap from the cooler to the end of the extension. The slp extensions I believe you can order for you specific cooler length so you don't have that gap. I would think that would be the way to go. If you are looking for a track and rails, I have 162 rails with a non ported powder max 2.25 for sale. pm me if you are interested.
I'm wanting to do this exact thing, is there any need to re-gear or re-clutch with the longer track?
Bump, x2 on the modd. so whats involved, longer track, longer rails, tunnle extension?
I was told smaller drivers is needed. what else is nessasary?

How to get to 159
Stretched mine 2 years ago and it has worked very well. My goal was to keep the tunnel shorter than what BRP would normally have, so I bought 151 tunnel parts for my 159 project. Debated on using the 144 cooler, but it was brought to my attention that the snow coming straight up off the track as it comes around the rear idlers, actual does the most cooling. If you were to use a shorter cooler, the snow will not be directly hitting the cooler, just passing by. If the sled is in good powder or loose snow conditons, there's no problem, but there are those few times when you need all the cooling you can get. As I said, I used a 151 cooler, but I also used 9" rear wheels, so the skid length was shorter than a standard 159, which helped with what I just explained. Front drivers for a 2.25 or 2.3 track, need to be 9 tooth on a 2.52 track (or smaller) or 8 tooth for 2.86 drives. Gearing that works for me, 19/45
and then some clutching too. For rails I went with Ice Age and they are nice. One last mod was to install XP drop brackets for the rear skid mount. Saves 1.5 lbs and gains 1" of height. The track was a toss up, as I wanted to save weight, but didn't here to many good things about the Challenger Lite, although they are 10 lbs lighter. After looking at them, I decided to go with one, but make it better. I did a lot of experimenting and came up with a track the works like a powder max, but is 15 lbs lighter.
And one last thing, I've get a new project and will be parting out the sled I just talked about (motor problems
), so let me know if there's interest in anything
