I might have to climb under the Libby this weekend(see my other post). If I'm under there I've been trying to decide if I want to go a little higher and looking for your thoughts on installing 2 additional upper rear isolators? I have the JBA 1/4" top plate, 3/8" clevis spacers and 4 factory upper rear isolators ready to go, but I could just do the clevis and 1 upper if that is a better option.

Do you feel 2 additional rear isolators per side is a safe, stabile and strong enough option for additional lift? If in doubt at all I'll just do the clevis and 1 additional upper rear isolator per side.

H&R Springs. 20.5" front and 21.0" rear at this point.

So you already have the 1/4 inch top plate and 3/8 inch clevis right? Thats all you can do in the front
For the rear you have two per side uppers in there now? If so you can add 1 more upper per side for a total of "3" per side but then that will make the rear an inch higher than the front .

If I install what I have I'm figuring an additional 1.25" front and 1.0" rear. That would put me at 21.75" front and 22.0" rear, if I'm doing the math correctly.

only downside to using 3 iso's on each side in the rear is eventually they will non-uniformly squish , some plywood or whatever cut similar to a toilet gasket with a couple gobs of rtv as glue on the vehicle side and then the normal iso between it and the spring will also work
