Looking at the Jimmy on the site listed in the first post, they did a lot more than just 4" springs. It's looking like they did their own 52" spring swap up front by the modified front spring mounts that are now in front of the core support mounts. Add to that some serious amount of sheetmetal cutting front and rear on top of a 2" body lift.

So yeah the deavers flex like mad and the 46" Micky's require a lot more trimming than 37"s would but to be able to use that kind of flex you'll need clearance.
