Sidewinder XTX 146 -20, track change

[srx700lt]

I have a Sidewinder XTX 146 SE - 20, and now I'm thinking of swapping the track to a one with larger lugs. Anyone done that and has any advice?
I was planning on getting a 2 1/4 (57mm) but it appears that is not available so the next is 2 1/2 (64mm). Does that work with 8 tooth drive or do I need to go to 7 tooth?

That is exactly what I am planning on doing. But it must be extremely close to the cooling lines in the tunnel?
And the rear bumper, is it from a 141"?

Clearance to hoses in front is 1,5cm. Rear tunnel, cooler hoses and bumper is cut 15cm shorter.

I’m working with the same sled a 24 xtx 146 so a 2.5 does fit in there with stock drivers? Or what did u have to do to make it fit

Did it fit and work? Or what parts were needed

I went with Avid 8 tooth drivers and Challenger extreme 64. I use 8 tooth since I wanted a bit more clearance between the track and front cooler.

How much was with stock drivers and where did you get the drivers from?
