with new rails and drivers it's doable. But.. that's a lot of money to spend to run a very heavy track with an antiquated lug design. I would expect significant performance loss with this swap.

Suspension aside, you'll need to change to the 2.52 drivers... You can get a 2005 900 driveshaft and it should be a direct fit from what I remember reading on here a couple years back. The 166 is a 'heavy' track as mentioned, but it also works a lot better than the 5.1 in setup snow like we get in the Cascades, it will have less tendancy to spin on hardpack or icy conditions.

Thanks

Thanks for the info I just had an 05 900 chassis sitting collecting dust thought it would make a great option on my pro but sounds like I will stick with what I have.
