How did you like the Composit M66 146 2.6 track? I am looking for something more on my 146SKS and not too many other option then the peak 2.5.
146 RMK
- Thread starter Wheel House Motorsports
- Start date
I talked to compost tracks about the availability of the m66. He said they only made a small batch and sold out early this winter. No more will be available until next fall. The only two options now are the Challenger 2.5 and peak 2.5 if you want a decent lug height.
I suppose a guy would have to go a little shorter on the rail but 141” 2.6 powerclaw would also be an option.
Edit: Ah, didn’t see he ^^ was looking for an upgrade for an SKS. 141s not gonna bolt right up.
I saw they have the Composit M67 Mountain Track 15 x 146 x 2.62 also in the 2.86 pitch, but again it seems availability is limited. I saw its a 2 ply track, being a flat lander there are lots of rocks to hit, 2 ply is nice.
Good review, I built a similar sled in the fall of 2016. After riding this sled over 1100 miles, it is everything I hoped it would be when we started the project. I like the camso track as it is durable and gets good traction. It does weigh 52lbs, 8 lbs more than a 155 x 2.6 which is the only negative I can come up with. The 146" is a 2 ply vs single ply 2.6, is full clipped and has outer drive lugs. I have thought about running the SKS 146" track that is based of the series 6 but in a 2.125" lug height, I would like to know the weight on that track. I've run a variety of A-arms and shocks on the sled, starting with Exits/Z-bros and have since settled on the Raptor Kinetic series front and rear coupled with the 39R from Raptor. The 39R gives the ability to both mountain and trail ride easily and the sled is extremely easy to ride over terrain at ridiculous speeds with the 39R/Kinetic combo. Handling is fantastic off trail and the sled is very easy to ride aggressively in the trees, it changes directions darn near on a dime

I talked to iceage about axys rails that could work with the 141” powerclaw track. They said the 146” bomber rails they make wouldn’t work. So I don’t know if there’s a way to get that track on the axys. Do you know? That would be my preference now that Composite is out of 146” tracks both m66 and m67.
Does anyone have experience with the peak 2.5?
That's all you do , new track , iceage rails and shorten your tunnel everything else fits.
Just helped a customer out today shortening a khaos to a 146. Rails, track, and taking 10" off the tunnel for one wild buggy.
We built this exact sled for Caleb Kesterke this year, if you follow his riding, its pretty obvious to see the 146 khaos is an insane buggy. As you can tell, its a fun little unit and comes around rather quick.....

The guy on the sled helps a ton tho
I have the weight for that SKS 146 track at my garage, and for 15x146 M67 also. I check them for you tomorow.
Calebs sled utilizies the Composit M66. A few members of our staff have thrown a leg over this setup and it is quite a bit of fun. Once there is a base you can tackle some very impressive terrain on these things. The light weight RMK with a big paddle track is very capable even in the shorter length. And with the shorty tunnel, it whips around more like a dirtbike then a sled.
Customer was hoping to get an M66 but sounds like they are out for the season so he went with a Camso challenger 2.5".
His quote after this weekends test ride was "wow, you can have way too much fun on this even in marginal snow."
Thanks for the info, do you happen to know what drivers he used? I am looking to use his build as a template to improve my own.
Appreciate your time, love your product it is indeed as awesome as the videos make it out to be.
Both started on the stock 7T 2.86 drivers. With a center ported 2.86 pitch track just rails and track are all that are required.
Calebs sled was converted to 8T Avid extrover 2.86 pitch as he was struggling to prevent ratcheting when riding low elevation coastal snow (Whistler). The m66 hooks very hard and wet snow and lower elevation resulted in impressive power and traction causing issues. Track tension was getting ridiculous and was having a distinct drag at higher speed. It got to the point the sled would not roll off a sled deck ramp anymore. The driver change helped greatly increase top speed and "spool up" time on everything being able to run normal tension specs and reduce drag.
This is some interesting info. I'll throw my experience into here just for other peoples reference.
Ridding in the flatlands at 900 feet; about 3-4 feet of generally set up snow. Type of riding slow, technical deep lines in the trees. Close to mountain type tree ridding difference is its just flat. Running the stock Series5.2 146x2.25 track with the stock 8 tooth driver and 2.86 pitch. Track ratchets like crazy, it has to be so tight it will not freewheel down a hill (or sled ramp like you state). Also going through drive belts like crazy, 3 this season one lasted 200KM. I suspect my belt issue is due to heat, the ratcheting due to the stock drivers just sucking.
So I have replaced my drivers with 7 tooth 2.86 extraverts to stop the ratcheting and also gear the sled down in an attempt to lower belt temperatures. Installed a 2.5peak track (80% of my ridding is setup snow, and in the flatlands), I know its a trencher but performs and setup snow, which is what I ride.
I am hopping to fix the ratcheting issue as well as belt blowing/temperature.
100% on track with all of your choices and assumptions. Running an insanely tight track as described results in tons of drag, bad fuel milage, poor belt life etc. Its like riding with the brakes applied. Being able to ride a sled with minimal rolling resistance is essential for peak performance. This is why we make almost all of our Polaris rails for a larger 8 or 9" wheel vs the stock 7.25". This slight increase in size helps create a smoother rolling more efficient system that puts power into the snow not burning it up in heat and drag.
Good news in this front, I was able to order the following :
