The kits do look good. Does anyone know what size they are going up to?
I already have 22" Mudlights on ITP rims for the Rear, & through the stock rear tires up front, but could use something narrower up front.

What kind of discount card did you have? I got mine for $519 with no discount card but he cut me a nice break on the regular price.

When I bought the RZR.the dealer I bought it from gave me a one time 20% discount on any parts purchase .I have been saving it till something came out that I really needed.Of course when I went to use it I couldnt find it ,I went back to the dealer and found out the salesman I bought it from is no longer there.Talked to another salesman and he was more than happy to give me another card.(I bought the RZR a year ago today).so I went over to parts and ordered the kit and they told me to keep the card for the next time.

I ordered just the sprockets and chain because I already bought the wheels, dealer said the chain was in but I would have to wait on the sprockets. the is a 15T and the rear is a 36T what is this going to do for speed and bottom end?

If I'm figuring it correctly Stock geraing is 2.58:1 and the new gearing will be 2.4:1 since the kit is larger tires this seems like it will be faster but may lose bottom end. Might be a slug out of the hole, and hard on belts. But the larger gears may be eaiser on the motor. Not sure what Polaris had in mind here. My gearing with an 11T is 2.8:1

Are you running 22" tires? If so can you tell us how the 11t sprocket changed top speed and acceleration? Sometimes with CV clutches when the using lower gears (higher ratio) the top speed can be increased when before the gearing change the clutch does not push the belt to the top.

I agreee not sure what Polaris was thinking by putting a lower gear ratio doesn't make sense.

Well I've got more done than just the 11T sprocket, which also affects my speed. I also have the C&D clutch kit. So with the 11t, clutch kit and 22" tires my top speed is 35mph. I have great bottom end which is what i wanted for the dunes and trail ridding.
