Aerostar spring isolaters.

Thanks, that's good info... I hadn't thought about re arching to a specific height.

It looks okay but its like the rear springs have lost alot of stiffness... On some occasions I'll bottom out on the axle bump stops. It's more frequent with people in the back.

Could very well be the springs, but the shocks play into that also. I’d check them if you haven’t, first. Shocks are cheap and easy compared to springs and need to be right anyway.
