Mike I think the 6 inch springs are actually firmer than the OME heavies. It's just that your OME heavies were magical. For some reason they were stiffer than normal and lift a truck as much as OME J springs. Devin and I compared the height of our trucks and they were about equal. He had your springs and I had the J's. So that's why I've come to call them "the magic springs"clownmidget said:It is definitely better in my opinion for both on and off road compared to the stock and the 850/863 OME springs. They are a bit softer than the OME heavies but firmer than the stock springs.
