Interesting.
Have you seen some failures?
I’ve never changed a bearing on a Polaris newer than 2007.
(Owned 12 different sleds since then)
One in our group went down and also read some posts about the bearing failures. Two guys also posted a Youtube review of their Polaris 850s. Both went down with bearing failures. Some of the commenters on that video also post about failures.
Came across this as I was looking for long-term reviews of the Polaris 850:
It's on Youtube and called:
Polaris VR1 Matryx 850 (almost) 4000 Mile Review
Might be a trail sled thing? Ive. Never seen an issue on rmks

We've seen it on edge and dragon RMKs without the zerk, but on an 850, you'd guess it was the bearing run. Poo has been cutting corners on bearing cost with cheap land of killer bats suppliers, 4k wouldn't shock me. Seen some rough PTO driveshaft bearings with as little as 1000 mi when changing tracks, but could be seal-related, too. They can all be greased, of course, with a needle.
Best option I have found. Ski doo rail scratchers all the way
My 21 Khaos jackshaft bearing will fail. It is pushing out all the grease. Polaris won’t replace it until it fails. So instead of them just replacing the bearing they may end up replacing more if I wait for it to fail.
As far as scratchers go, the stock OEM ones work fine. There is an easy way to stop them from breaking when you back up, don’t reverse with them down lol
As far as the scratchers being Holz and the suspension being Holz, only Mark-Holz can answer those 10+ year old claims if it was inspired/designed/stolen from/by Holz. The one thing for certain is that it works, and it works so well it hasn’t really changed much in that time. Hey it could be worse (t-motion)

my stock 17 cat scratchers are still working fine, 2100 miles, maybe half of that with them down, couple of reverses....but was thinking of these if they ever break. http://www.carbonsled.com/accessories.html
I thought titanium was all the rage? seems like a good spot to utilize the extra durability and weight savings of Ti. Or do they not throw the snow?
i like the cat setup with the 90 degree bend that grabs the snow and also hooks over the rail when not in use so no extra hardware needed. i thought the polaris was same but idk.

“Extra durability of Titanium?”
Never encountered that..........
Lightweight? Yep
Weaker than chromoly steel? Yep
Titanium fatigue and breakage? Yep
Just my experience.
^ weird, ive bought 3 or 4 upgrades in Ti and always experienced the opposite. very durable material and light, doesnt rust like chromoly. Not sure if buradnt runs scratchers but i think his motors and clutches are held together with Ti. I had an old SLP ski scratcher break off in my hand the other day on my vintage mod, so was looking around at options, thinking of just putting the cat scratchers on it
Ran all sorts of ti arms and even have titanium hammers. Doesn't rust, brittle, snaps instead of bends. Kind of like 60 grade rebar vs. 40. If an engineer is involved you are using 60 grade. Bend it over in a doorway and it snaps once in a while. 40 grade bends twice as easy but doesn't snap. So how great does that make it?
The sta-cool scratchers are not labeled as sta-cool 3 just pick up a set of Sta-Cool scratchers they will either have 3 or possibly 4 coils as of late and exert great down pressure compared to the stockers.
You can bolt the Doo scratchers onto Khaos rails and not have to drill any holes. Did it on bud's sled. Standard RMK you have to drill.
On Axys rails same thing and no need to install hangers - scratcher ends tuck into the rail opening
