i got a 2001 600 and blew the track the other day. i'm sure its a 121" x 15 track but was wondering how big of lugs i can go? any opinions on a good place to get a track?

TracksUSA is hard to beat for their prices, speed of shipment, and service.

I'm pretty sure you can get up to a 1.5" without notching. Anything over that and you will have to notch it for the coolers.

Yes I belive 1,5 is the most you can do!
I have a Challenger 1,5" on my 800 and it´s close on the coolers

Good luck

I run a notched 2" on mine. Installing is a pain by the front cooler, but it fits.
