Soft Ride Replacement Leafs for a Pre-Runner DC?

Does anyone make a set of stock ride height leafs but at a "softer" spring rate?

I have the dreaded frown, the rear sits lower than the front. I really want to replace the factory leafs, but I don't want a more harsh ride than I currently have, other than hunting season, this is a daily driver. It doesn't help riding in the wife's 4Runner either.

Is there another option, AAL only help with capacity, correct? I rarely carry more than a few hundred pounds, I have a trailer for anything over 500lbs. The ride is already more harsh than my previous SUV, which isn't a bad thing, except the lacking maintenance of the local roads, most of which are county. I plan on ordering shocks and "quick struts" when I replace the leafs, along with a 4 wheel alignment. The shocks and struts were replaced 30,000 miles ago by the PO, but for the life of me, I cannot find a name or part number anywhere on them.

I looked at the Wheelers 4 leaf packs, but it doesn't go into detail about the spring rate or ride quality.

Thanks for any help.
