A friend of mine wants to install a powerclaw 162" x 2.6" on his 2012 Pro RMK 155. I've done a search, and haven't come up with a definitive answer. The plan is to get a set of 163" rails, tunnel extension, and Avid 7 tooth, 3.0 pitch drivers, which are 3/8" smaller in diameter. We will have to trim the rails and add an anti-stab kit as well. My question is this: does the chaincase require modification to clear the drivers? I know it was needed on the IQ chassis, and not necessary on the 2013 - newer Pro with the Quick Drive... but what about the 2011-2012 Pro? Thanks for your input, just trying to determine if this is a viable option for him.
