I`m sure ther will be a few companies out there that will figure it all out and make something work. Now whom that will be remains to be seen. But in the meen time, all i`ve heard is that the diff pro`s are grinding some of the material out of the case to make the gears clear. I`m guessing they`re NOT to worried about the housing strength in general and removing some of the actual housing material, otherwise we would be hearing about it all over the forums. The ones i myself would be watching for and listening to, are the late 2011 on up year 4th gen guys that have actually installed 4.56 ratio`s and lower. They are going to be the ones to ask... they`re in the "know", ya know what i meen..?
