2017 mtn cat 153 21/49?

[madsledder]

Hey all. I am curious if it is worth doing the higher gears on my 17 mtn cat 153 3". Y-pipe and can, and doing mds weights for this season. Ride 3-8000' trees, climbing all around mtn sled. Would go from 19/50 to 20/49. Any advice would be great. Thanks in advance.

I prefer the 2.45 to 2.50 gear range makes the sled a bit more lively. a lot smoother on take off with more pull in the mid to upper and you can re use the stock chain and just change gears.

MDS weights are going to have it upshifting harder already no? I wouldn't.

So does the 20/49 fit with the stock chain? Where’s the best place to purchase these gears from? Thanks

yes 20 / 49 will fit with stock chain.
you can get them from bdx or cat

I would double check with your dealer to make sure they will fit but the

20t is 2602-824 and the 49 t is 2602-875
