According to their website, the T4S system is listed for 2017 models.

Don’t know where you’re hearing this six months ago I bought not the original camso track that always had a Fitkit for my 2019 xp1000 but the newest model released this spring which is much better and only $200 more. You do have to have the right kit they swap sprockets for the xp1000 power
On top of that cameo now makes the “Polaris” tracks for them. Atvtracks.net has the best prices and really knows more than anyone. And they will make sure they send you the right setup for whichever machine you have

 

Call ATV Tracks.net - great guys - best prices on CAMSO tracks. YES - CAMSO has a kit for your late model Sportsman with arched a-arms. New model is X4S

If you're only planning on riding snow, I'd get the T4S, not the X4S. The X4S is the new model made for all terrain, but are heavier and more expensive if I recall correctly. We have two sets of the T4S and they have worked flawlessly so far. The third model, the R4S are too light duty for me.

 

Nope - the T4S is all terrain, it's what I have. There are beneficial updates to the design of the X4S over the T4S. Not worth the upgrade to me, since I already own a good T4S system but if were buying now, it would be the X4S system for sure. Your choice but there is pretty small difference in price when you are looking at a 4G$ expenditure. JMO

 

If you read what I wrote, I didn't say the T4S isn't all terrain. I said if one is only going to ride only snow, I'd suggest the T4S. I paid $3,800 delivered for my latest T4S set and they want $4,300, so the difference is $500, which is significant and not worth it to me.

 

Interpretation - I'm glad you like the T4S system, I like mine too. But riding in snow only has nothing to do with it.
I'm betting the T4S will be discontinued when their stock is depleted.
