I'm getting ready to install extros on my driveshaft and was wondering if you guys run the outside introvert cogs along with the inner extros, or are you running just the Doo introvert/extrovert inner cogsets? Thanks, Jay

Yeah I ran just skidoo's, Honestly this was the best upgrade Ive ever put on a Yamaha. I put my new track on with extro's and didnt tighten it once in the 1800 miles I put on it. Ratcheting is eliminated!

OK, so I'll leave off the outer drivers, thanks, Jay.

I run just the Skidoo drivers also and they work flawlessly. No ratcheting no matter how loose the track is (at least as loose as I'd ever let it get).
number1kyster, did you install the skidoo drivers on your 07 RTX? If so, you should really trim 1/4-3/8" off the front of your rail tips (the rubber pieces). With the ProActive suspension and Skidoo anti-ratchet drivers, the tips of the rails touch the drivers when just the front of the suspension is compressed (like when riding over a snowbank at low speeds).
With the monoshock skid I don't believe this is an issue (the rails are shorter with the monoshock).

Also, where do I place the collars that are on both sides of the outboard drivers, do I locate them on the new extro drivers outer shoulders, or to they remain in their current stock location as to index the drivshaft properly?

My vector had the pro active skid and I never had any issues. Are they rubbing on your RTX?

I doubt you'd notice any issues. They only interfere by roughly 1/8" and only when the rear of the suspension is fully extended and the front is compressed just the right amount.
After installing mine I took my sled and cycled the syspension through everything I could try by manually rolling it up and down obsticles (turning the secondary by hand). When they touch I could still crank the sled forward and there was a sortof mild "thump" "thump" as the sprocket teeth compressed the soft bumpers and travelled through the interference.
When you're sledding you'd probably never notice it and the chances of get them to touch when riding is very low (except when going over a snowbank slowly - if you weigh just the right amount).
My only concern was that the bumpers might loosen off a little faster than they should because of every now and then being hit.
To make sure there were no problems I drilled out the rivets on the tips and cut them down with a blade and reshaped them with rough sand paper to look stock. When I re-installed them I used a couple of nyloc nuts and bolts in each (drilling an extra hole ahead of the stock hole to make sure they don't loosen off over high miles - with a single rivet or single bolt they tend to loosen off).
