My new to me 2001 Supercab Ford Ranger has always sat a bit low in the
rear even when empty.

The wife's extended cab broke a leaf at some point, she had a spring
shop fix it, somewhere between 100 and 200.

My regular cab was sitting low, found out I had at least one broken
leaf on each side, got a pair of spring packs from the junkyard for
50. Kept the old top leaf from the original packs, cut the eyes off
the new top leafs to use as overloads, no complaints after over a
year...
