Did RockAuto screw up these descriptions?

[saxart]

I'm putting 1/2 springs in my C-10 to replace the 50yr old "Heavy Duty" springs so that the truck rides better. I went on RockAuto and ordered AC-Delco "Variable" springs. The correct part number arrived, but when I compared them, they looked exactly like my old springs (2 or 3 coils closer together) and the spring wire actually measures slightly THICKER on the new springs!



Here is a screenshot of how RockAuto describes them. Do the springs at the top (more open coils) look more like 1/2 ton springs even though they're described as "Heavy Duty"? (I think they have the descriptions flip flopped)



I've never actually seen 1/2 ton springs in person, so I'm just trying to confirm which is which...
