Axys 155 3”
- Thread starter Super A
- Start date
Almost all of us here at the shop ride late models Pro-RMKs. The majority of the guys have 155"- 2.6" tracks. A couple with 163"- 2.6" tracks. I personally ride a 2018, 155"- 3" track.
We ride extremely technical terrain, usually in deep powder in the trees. There is definitely a noticeable difference between the 2.6" and 3" track. There's times when I can get up a steep and deep embankment that even the 163" - 2.6" tracks seem to struggle with.
Perhaps it's the gearing ratio or weight of the chaincase inertia, but I also seem to have better ability to "crawl" out of a situation versus the guys running the quick-drive system.
I'm biased, but I think the 155" - 3" is about the best setup there is at the moment for the type of riding that we do. Of course not one sled fits everyone or every type of riding.

In the 155 length - I find the 3" to be less squirrelly than the 2.6". It holds a line better and goes where you point it. With the chaincase and 3", you give up a little response and "snap" to the 2.6", and the 3" with lower gearing is noticeably slower and less fun on anything resembling a road/trail. Overall, in the 155 length I think the 3" would be my choice, it climbs well and can pick the front end up (or hold it down) quite easily via shifting your weight around. Super fun sled in tight terrain (or any terrain).
I put a camo 3x with the pro belt drive gears on my 16’ axys half way through this season. The 3x grips the snow better and launches you forward sooner. The 2.6 spins a little more before significant forward movement. In stop and go technical situations the 3x is pretty agreesive in getting the sled where you want it. Some people may not like the aggressiveness and prefer what I’ll call a more lazy track (2.6), if that makes sense. The 2.6 is a really good track, I just like the 3x better. My turbo axys got a powerclaw 3”, best track ever, but that’s a 162.

Thanks guys, I am currently on a ‘17 155 with the 2.6. I was just curious if you guys had the advantage on me in the tight stuff. I think I might like the gear down of the chaincase and the ability to slow down and have more time for decision making. Good stuff. Snowcheck is just around the corner.
How is the 3" track in marginal snow, I don't get to pick the days I ride having an 18 hr commute. The 3" sounds really attractive but I'm just wondering if it's not a bottomless day would I still be happy with it. Great thread, I hadn't considered the 3" before this.
Pretty much this entire year here in CO has been marginal at best, and the 3" does great. Even in crusty old windblown snow, or 1" on top of hardpack, temps haven't reached higher than 124 F, and that's without the scratchers down. Having owned 3" tracks for the past few years (Ski-Doo T3, and now my Axys), I will most likely never go back to anything less.
This winter I've had and ridden a 16 with conquer 155, a 18 with 163 2.6, another 16 with stock 155, and now a 16 with stock 3".
For overall fun, maneuverability, and messing around, the 155-3" gets my vote!
I am very happy with the way it hooks up and still feels short when maneuvering.

It's not the chaincase, it's the track and much lower gearing they put in there for three 3" track.
I have a 156 X3 on my Pro.
Belt drive.
I can slow down and give up momentum with far less penalty than others.
The 3" track and low gearing is amazing.
If you can, go back to a 2.4 or 2.6" track (with a chaincase and taller gears) and compare.
Remember, the chaincase is less efficient and has more rotating mass.
Remember.
It’s yet to be proven that the belt drive is more or less efficient.
(By actual measured gains)
I really like my chaincase sled (162x3 series 7) with a 20 tooth top gear. (Slightly higher gearing than stock.)
Seems to load the clutching well and trackspeed is good.

Yep, those 3" lugs do load the motor.
The 3" lugs are designed for off trail and deep powder use. If you are mostly on trails, you'll have a harder time keeping the track lubricated and the engine cooler. It can be done, but you'll be constantly checking your water temps.
