Track lug depth for an '02 rmk

So i have had an '02 rmk for about 8 years now and when i got the thing it had a 156" 2" 2.52 track on it. Well since i was not riding it out west at the time i sold it and put a 1.25" ripsaw 151 on the sled.

Quite a few years have gone by now and my main riding partner has a new truck and just decided to buy a '09 summit so we will be heading back to my first love...THE MOUNTAINS!

I am looking at a 159" 2.125 2.52 series IV polaris track...mainly because i can buy a brand new one pretty darn cheap.

My question is:

1. How deep of a lug can i put on her before changing out the drivers?

2. If i go with the 2.125 how far am i going to be behind if my partner is riding a 2.5 154 16" wide track

3. Is there really any advantage to be putting different drivers on spending 2.5 times as much for a 2.5 track?


Keep in mind i have to keep switching back and forth from my mountain set-up to a flatland set-up

Thanks for the responses. I decided to go with the 2.125 just because of the cost factor.

I got a camoplast 159" 2.125 for $225 and the thing has a 100 miles on it and i got it local so no tax or shipping.

For now i am happy with the shorter lug and maybe later i will swap out drivers and all that good stuff but looking for cheap as possible rite now.

I should be fine keeping up since he is running a 800r with a rtek 860 big bore but he will be running low compression heads and i wil be running my performance edition kit 800 with mountain heads so power wise we are gonna be close and he is running a 16" wide 155 2.4 i wont be at much of a disadvantage
