My back-up sled is my old 2002 Pro X 600. Since I am not using it much and I will never get the money out of it that I want, I am thinking of turning it into a sled I can still use as a back up and build it for riding out west the couple times a year we plan on riding west. I will be pulling the motor and building a 660. I would like to go 144 with the track but I am not certain on the track yet.

I am looking for ideas of what to do to the sled. I would like to build it more for riding out west than keeping it for a back up.

Any input is appreciated.

What you are wanting to do with your sled is basically exactly what I have except with an 800.

If you are going to use this as a back up sled/ out west sled I would recommend you use a camoplast challenger 144 2 inch track. I have used this track for a number of years on my off trail sleds. This track shines in both on trail and off trail conditions. The lugs are soft enough that its not a trencher special but durable enough for the lugs not to come apart when you ride it on trail.

http://www.tracksusa.com/challenger2.html

I dont know how much you plan on riding this sled out west in the deep snow but one of the best mods you can possibly do is a drop and roll chain case. It helps with the flotation and keeps the sled up and on top of the snow in the deep stuff.

The second best mod is Extrovert drivers. These are worth their weight in gold. You wont believe how the track hooks up on long climbs.

As far as the tunnel goes. Do you plan on using the stock tunnel? If you do I would recommend at least using a Van Amburg tunnel extension. Aftermarket tunnel us a Van Amburg or a CR racing tunnel. Aftermarket tunnels might cost alot but they are worth their weight in gold when it comes to boon docking.

Now the biggest thing, rear suspension for a off trail or mountain sled using extensions on the stock suspension isnt really the best choice. The Pro X rear skid really wasn't designed with deep snow performance in mind. Your much better off getting a full 144 skid from an Edge RMK and using that. There is a HUGE difference it both weight and flotation between the two skids. Aftermarket go to either a Holz Alpha X rear skid or a Timber sled Mountain tamer. EZ ride is another option but from what I have heard you have to run the track pretty tight with those skids so they dont ratchet.

The stock trailing arms are about as good as it gets. It might not be the lightest, but there aren't many decent options left. Holz stopped making theirs and they were about the best there were aftermarket wise. No matter what aftermarket trailing arms you go two they all are going to make the sled steer harder. Get a good set of shocks on the front end and you will be golden.

This is a start I can elaborate.

Both of these sleds look awesome! Might be a little more than what I wanted.

I was thinking rail extensions to 144. If I find an RMK I might think about that. I still need to keep it trailable for flatland riding in the event I need it. I will probably go with extroverts since I will be tearing it down that far for the track change. I do not want to replace the tunnel so I am going with an extension. Whose extension should I look into?

How about skis? I had been running project X and I like them but I am not sure how they will do in some deep powder.

I will need to start collecting parts this summer.

Thanks for the input guys. Any other input would be appreciated.

Thanks for the props on the sled.

Van Amburg Makes a great tunnel extension. Might have to call them about the edge pro X one though I dont think its one the website anymore but they still sell it.

As for skis Simmons or SLP powder pros work very well. I had a set of SLP's on mine but I wrecked one. Need to get another set.

I have an 02 X 440 that was converted to a Non-Ves 700 with a 144x2 challanger. I had it out in Cooke City for the first time a few weeks ago and it did great!

Stock rear skid with 144" ice age rails
HRP big wheel kit
custom made tunnel extension

I have heard great things about the 660 kits and the 685 kits.

I dont have a drop and roll chaincase and my 2" clears the front coolers but should be notched a little for the upper coolers.

If I use an RMK skid will I use the stock location holes?

What size track will clear the stock front cooler?

On a stock Pro X a 2 inch track just rubs. It would be best to run a notched 2 inch track or a 1 3/4

The RMK skid would not use the stock holes on the Pro X tunnel either front or rear, you would have to get measurements out of the sled the skid came out of to put the skid in your tunnel. Its not near as bad as it sounds. A little measuring and some drilling, move some drop brackets your good.

I would go with a SLP tunnell extension, the one I got from someone else was thinner material and now I need to reinforce it. The thing you need to watch when using a RMK suspension is ski pressure. I had to mount mine as low as possible in the tunnel and it still is a little heavy on the ski pressure for powder riding. That is due to the long travel front skis.
