ok i had a 144 last year and when i bought the sled (98 srx mod).... i just put a 151 under it and was woundering what kid of gearing would be recommended i don't know whats in it now .... i have had the chain case off a ton but i get tied up in the project at hand and haven't checked.... ounce i find out what you guys think ill check it.... i ride in deep deep and steep snow.... all mountain and i ride at 7000 to 10000 ft so any help would be great thanks guys...
 
sounds like my kind of ridin - I'm running 21/42 gears with 151" - 2" ported, finger camo track. She never poops out in the deep. Seems to work very well.
 
shoot for anything 2:1 or more, with the biggest top gear you can run. at your altitude i would push closer to 2.25:1. if you have 8t drivers, you need to factor this into the equation. i have a chart somewhere that shows this. also, check for chain length, as some combos require 68 link and some 70 link. if your sled gearing worked well with the 144, your probably still good on the 151.
 
I ran a 20/40 or a 21/40 on my stock 151 viper at those elevations and it worked good. I had hartman do the clutching and that is what made the difference.
 
19/42 with 9's = 2.21 ratio, 21/42 with 8's = 2.26, and 22/42 with 8's = 2.16

21/40 with 8's (I'm guessing that's what you have) = 2.15 so really it makes no difference. Just depends on what drivers and which gears you have lying around:)
