    On my 96' 2wd I have a 3 spring(i think 3) leaf pack on the rear. I want to put a set of heavier springs in back. Are the 4x4 springs heavier duty? Will 4x4 rear leaf springs fit a 2wd? I looking for inexpensive way to add spring capacity, before I go off and buy progressive overload springs etc.
    Right now I put in 500lbs of feed for cattle in back,springs are inverted and truck will bottom out on rough roads.

    You have a '96 with 233k miles on it already.500lbs inverts your springs....Your spring packs are shot.You should replace them.Check out a junk yard or pick a part.

    I agree that your OEM springs are obviously 'shot' ...

    ... But swapping to 4X4 leafs won't help (much).

    Putting 4X4 (leaf-over) leafs onto a 5-lug (leaf-under) setup will *lower* your rear by 1 - 2".

    In any case - the spec payloads for a 4X4 are approximately the same as for your 5-lug mini. In other words - the 4X4 springs aren't designed for a heavier load than the ones you already have.

    I guess I should have stated the springs are shot, figured that was gimme. Good to know the 4x4 springs wont help.

    The springs aren't the only thing that determines the payload....Your springs being old and beat doesn't help...but the rated capacity for the truck is based on frame and axle construction, braking ability, etc etc....You can't just slap different springs in and expect to carry 1000lbs more than before.

    Good point brunes, cargo capacity is subject to the GVWR of the vehicle minus empty weight and then you must consider front axle and rear axle weight ratings by factory and you cant forget the tire weight rating capacity.
