Rear idler wheel size?

[snomanz600]

Hey guys, first off this is my first time posting and just want to say this site kicks *ss!!! If it wasn't for this site I'm not sure if I would have bought my Nytro. My question is does anyone know the inner and outer diameter of the rear idler wheels on a 08 rtx? I tried exhausting the search button before posting with zero luck. Thanks in advance.

If you talking about just adding the 8" rear wheel kit, you would not be able to go to 144" Your 136" would still fit. Does someone make an 8" Kit for the Nytro other than OFT that works with only their ext's ?
