I thought this was some thread about a stripper.

 

Been their done that!
Big mistake to try to level up worn out springs.
Why well they just try to level your ground to bumper and say you want them a little beefier.

So they re-arch both spring packs then they had to add other spring or arch one spring a little more then the others to make up for the weak spring pack.. You will end up with two different looking springs packs when one is weak and worn out.

I would never have any springs re-arched again if one was weak.

This is when, I had a c/o camper on the truck. It's was kind of odd that both my passenger side springs were weak.

I first put in the front a pair of Add A Leafs that did some good but the right rear still sagged some. This was when, I later had them re-arched.

Yrs later found good front replacements and some HD rear spring at the JY
on a mid 70's pickup. It leveled my truck out and installed all poly bushings in them.

I'm not really in favor of re-arching springs either, it's kind of a temporary stop-gap. Especially if you can get a good set of springs for cheap.
