Good info. I spoke to DVS and provided measurements, they advised the 5” bracket. My Slee 4” HD progressive coils lift my rig more than 5” when unloaded, which is the case most of the time. I have room for a 5” rise based on my home made bumpstop drops. And, actually, I’m debating just making my own riser anyway. I know the DVS unit is a very nice, simple solution but I would enjoy the project.
For reference for others, I measure 25.25” hub to fender wrapped around a 37” tire on 3.5” backspace.
I think “back to factory geometry” is never an automatic statement, because your suspension is not traveling within factory designed arcs. If I were Delta, I wouldn’t be saying that it’s designed for 2-3” of lift for the standard part since it’s clearly good up to 4”.
Not saying don’t do more - I have 2” bumpstop extensions that perfectly protect my shocks with eye adapters and I could have fit more - but I think there’s some solution looking for a problem there and longer lever arms aren’t automatically neutral.
Delta’s own pics show about the angle I have remaining. Obviously there’s a point where the angles are still decent and if it fits, why not?
Also, I retained my adjustable panhard for the reason of pinion angle changes so that tiny bit of remaining adjustment to have the axle perfectly centered was simple enough.
