AAL Installation: what height change to expect with a medium static load?

What sort of final height should I expect to be added to my vehicles which currently has sagging OEM suspension with the wheelers 1.5" progressive AAL with overload kept in?

I'm trying to get a rough idea of where my rear will likely sit after settling so that I can set the preload on the front billsteins accordingly to maintain the factory rake.

I've measured the distance between the ground and center of the fenders on all 4 tires, measuring several stock, unloaded TRD off-road and found that im sagging by approx 1" in the rear and 1/4-1/3 in the front.


Driver side
Rear 36"
Front 34, 1/2
Passenger side
Rear 35, 3/8
front 35

Will the AAL + overload add approx 2" to my current ride height, bringing me to around 1" over stock in the rear, meaning I'd want to target 1,1/2 or so in the front to keep a slight rake for when I load materials or gear in the back?
I've heard that progressive AALs decrease spring

Visually my ride looks pretty damn close to level and the rear leafs have a slight negative arch which I'm looking to fix , restoring positive arch to the leaf and having a rake so it doesn't squat when I have a load or as badly with a trailer.

Things I have bolted to my vehicle are.
Steel RCI sliders
Aluminum RCI engines trans, ransfer case and cat skids.
Aluminum RCI a arm skids (below Axel)
OEM roof rack
Steel RCI shock Skids (below axle)
Synetic USA rolling aluminum tonneau
Steel RCI bed stiffeners
Yakima overhauled bed rack plus side load bars.

 

Nobody can tell you with any certainty. Every truck (even the same year, model and trim) is different. And every leaf spring and AAL is different. It's just how they are manufactured. There is always some variance.

What I can tell you is that AAL's are a bandaid for a sagged leafs. You'll get a temporary improvement but the AAL's will too sag after a short while.

If your leafs are sagged, you need new leafs. Period. I highly recommend Deaver, reach out to them to see which leafs would work best for you. Don't cheap out with ARB or some shit or you'll have the same problem again in 3-4 years (been there, done that).
