Track Extensions

I always wanted to take a REV Chassis and put a Polaris 144 Switchback skid in it with the tipped rails and slap a 144 X 1.75 under it. I really think this would make a fun set up. Would have to do some research on mount locations for the skid but I am sure it could be done. You could find parts at Haydays for a good price too! Just a thought!!!

Think a 500ss Ski-Doo has enough umph to spin a 146"x 1.75 track? ...and still be able to trail ride comfortably 65-70?

I'm curious why you would want that much track to trail ride? The 500ss is a carbed, almost 600cc engine so it will probably spin it O.K. but it will definitely be a struggle in deep snow.

I'm just looking at the pro's/cons of of which way I want to go. I understand the longer is going to be overkill on trail, but I don't want to wish I had more riding off trail.

I've always liked the idea of haydays, but the 16hr roundtrip drive to possibly save a few bucks hinders that option. Most likely I'll be checking forum classifieds or just go to tracksusa.

I don't know what year this sled is, but, I am thinking that the longest extension kit you will find for this one is 136". You may have to get creative to get this one stretched to 144 or 146. An additional consideration would be the cooler/heat exchanger, with 136" you may not have an issue, longer you may. Just something to think about, even if I am a Cat guy.-Mezz

if you do this and and are short of power change the drive sprockets to the 600 summit carb spec and you should have plenty of power but you would lose some top end - my buddy has an 07 600 summit and I think it tops out at 75 mph but your would not want to go that fast for long- good luck

roughly $50 more, depending on track, to go from 137 to 146. I've had trouble with overheating before, so thought about getting a larger cooler too.

You can do what ever you want. This particular project will probably result in a one-of sled that won't have much value at trade in time. Why not just buy a ready made long tracker with a bigger motor that for sure can run trail speeds? Again, you can do whatever you want. Just a thought.

I have a friend that did this very thing: Switchback Assault skid on his Rev MXZ 600 SDI. He's using oversized idlers so he's running a longer track than the 144". (I can't remember the exact length). He is still running the stock cooler and it's fine off-trail. Scratchers are a big help for trail riding. It's been out to WY a couple of times and he's had a lot of fun with it out there (he was there this spring when we stayed across the street from you guys). He loves to work on his sled so I can't say it was a trivial swap but it works well.

Just extended my 2000 Yamaha V-Max 500 Deluxe from 121 to 136. Dropped a tooth in the top gear and everything is good. I'll spend a little on my old sled before I'll spend alot on a newer one for the amount I ride. No it didn't add any trade-in value but it add value to me and the riding I do and that's all that matters.

I'm kind of thinking along the lines that Grub touched on. I extended a 121 ZL 500 EFI to a 136. Then I did a seat mod, added a handle bar riser, then had to add a throttle extension, rebuilt the skid, did a few other things because I kept trying to make it into a sled that it really wasn't. By the time I was done I probably had 800 to $1,100 into it thinking it could become that sled that would allow my kid to go off trail. Honestly if I would have just sold it and put that money toward a used 06 crossfire I would have been close to having the cash to buy one. Instead I had a season and a half of wanting something that sled could never become. So now I sold it for what it would have been worth even without the new longer track and everything else and ended up buying a Crossfire so we can finally get what we really wanted in the first place. Too bad I wasted money on all the upgrades.

All that being said, look at getting a used sled that meets your needs before spending a lot of money on a track and rail extensions.

yeah I my self have spent lots of time and cash over the yrs extending trail sleds.
not worth it keep the trail sled for the trail and buy a old M7 for 2500 to 3500 all day the m7 will way way out perform some patch job doo trail sled there is no such thing as a true crossover sleds any way. u will be much more happy in the end with a trail burner and a mountain sled. a crossover in the woods is just frustrating and a trail sled conversion in the woods is just plane disappointing

I almost pulled the trigger on a tracksusa 144 extension kit last year for my 600 Fusion but decided against it and just bought a replacement short track with a little more tread and better grip. Makes it a lot better for on trail and for the off trail you see in the midwest. I'm glad I didn't go through all the trouble - I've come to the conclusion that trail and mountain sleds are night and day different. I'll probably do what Ezra said and buy a used M6 or M7 next year. I've rented those a couple times out West and they're a hoot. Just wouldn't want to ride trails all day with one. I understand people doing so if they primarily ride off trail or West, but if you're mostly on trail, the extensions seem like a lot of money and work compared to buying what you want already together.

I'm with Ezra on this one. I own a trail sled,crossover,and a mountain sled. Two of the sleds I bought used and the price was very affordable . The best set up for me,would be a 4 stroke boondocker/trail sled and a m8 or ProR 8. That would cover all of my needs. To each their own.....
