hey guys quick question. ok i have a 00 xc sp 500 and i wanna go racin snowcross with it i wanna gear it down, does anyone know what ratio i should put in it that would work for snowcross with alot of torque?? thanks guys

19/43, and more helix, if you have one. A HSP34X, with secondary in #3, stock silver/blue, or a blue/orange #2.

hey what do i want a 7/8" or a 1' sprocket

hey guys how wide would the sprocket be 11, 13 or 15 thanks for you help

You want a HYVO. Only one width available.

i can only find a 42 tooth hyvo sprocket should i just get that one

use robs tec tips for polaris sleds on the is web site .... take your gears you have now figure out what chain you have ...72,74,76 long and go from there! If you have a gear ratio that like 1:80 try a 2:00 this will slow it down top end but it will be a rocket from corner to corner!

You can run the 19/43 with the stock 70p chain. You do need the hyvo gears for your sled, so get the 43 bottom.
