Another Question on Front Coil Springs

Oem is Oem. Did HR change them, I suspect not, My friend and the one we owned were rated for 6000 lbs or so. We were close when loaded up. HR could have order the front different than Chevy standard. Our Ford is rated at 7000. I would think you have gotten there life out of them. Only you can decided what stiffness or firm ride you want. On my 7000 front axle I decided it was too soft, so air bags were install and that way very well worth it. On the P30 I just air up the bags to make thing better.
