I have a good 05 900 shaft if you need one. Pm me if interested. also if you use avid or wahl anti ratchet drivers you will need to trim your suspension rails for clearance. i also have a set of stock polaris drivers off a 2008 dragon that will fit the 2005 shaft.

You will need to change the clutch side bearing to a sealed bearing... and you can only use drivers intended for the 2007 - 2010 Dragons on the shaft... the PRO RMK 2011-12 Drivers are not correct for this shaft (spline is slightly too small)
I recommend going with a set of 2007-2010 drivers from a Dragon BUT... dont install the center driver.

why not the center driver
I've really seen no real life benefit to it at the track-tension required by Polaris for the RMK's
Proof is in the pudding...the turbo sleds with big tracks from Struthers (Carl's Cycle) run without the center driver and normal involute drivers at these same tensions without issues....They are one of P.I's "big shops" they work with for development.
PI just seems stuck on the center driver idea.
I've personally removed the center driver from the shaft on dragons and Pro's, running the prescribed track Tension outlined in the Polaris manual and have seen no additional ratcheting... even on 12 lbs of boost (250+) HP.
The Center driver WHEN it ratchets will put stress on the drivetrain and track when the track "crashes" into the tunnel from lifting up and over the teeth of the center driver . The 3 driver system when it ratchets ... lots going on there.
Although Polaris engineers have refined the center driver to shed ice-buildup better lately ... The center driver still attracts a good sized ball of ice in high moisture-content and spring snow conditions (from my personal experince) ... adding weight, rotatiing mass, and promoting ratcheting.
Heck...they went to an aluminum shaft... why not ditch the center driver to save another 1lb of weight.
No offense to the Engineers at PI that pulled off what is, IMO, the best sled all around sled lately. I just don't see the benefit of the center driver in real world applications that run in other than CO/UT Pow.
If PI is counting ounces and "beans" on this sled, IMO, consider, seriously, deleting the center driver.
My 2 cents...
