Can someone please confirm that the coils I just installed are in fact the light duty OMEs and not some kind of mix/match. My 4-door JK with hardtop sits perfectly level with absolutely zero sag, the springs are 616s fronts and 617s rear. Different web-sites selling OME springs list various different parts numbers for the light duty/heavy duty versions. After the ride result was not what I expected I just want to make sure I installed the correct stuff. Thanks.
