prefabricated spaces are only like $25/ea.
I can still see a minor need for bags even with those beefed up springs but if you’re taking out all the sag it’s now a bouncy house on wheels. I couldn’t see any need with 8800lb springs and your load. But like you I’d keep em if I had them already for minor corrections
The firestone support extensions are
1-1/4 to 1-1/2 height. Mine are 2" height.
Firestone's are U shape with one hole for the bolt. The problem I experienced is the bolt shifts around and works itself lose and has bent. Several times the bottom bracket falls off as the nuts work lose and fall off regardless of locktight, double nuts. Never tried nylock nuts or crushed nuts.
My 2" square metal lift brackets have two holes and hold the bolt straight and steady. I have not noticed the double nuts trying to work lose yet. I think the box with 2 holes hold the bolt straight and steady lessening the action that made the bolts work lose. The taller profile puts the airbags in a more desirable position too. The metel was free scrap. All I had to do was cut, deburr, drill myself, saving some bucks.
So far, they are working great!
