Which OME did you drive? Stock? Medium? Heavy? I have the medium in mine, and if it were any softer I’d not be happy with it. I’ve read a lot of people saying OME is too stiff lately, so either they have changed spring rates since 2014, or daily driving a 3500 Diesel has clouded my judgement. Both I and my wife far prefer the OME in our ‘99 over the AHC in the ‘06 we had.
It was the 1.5" OME medium. My feeling was that it was the shocks, not the springs that were so harsh, but of course I couldn't say for sure. I've driven plenty of work trucks that were very stiff, and this 100 was as stiff or stiffer. It was loud too, over every road imperfection. I've seen a lot of complaints about how stiff these kits are, and I think it usually boils down to the shocks. I think the springs in their kit are fine.
The ironman foam core pro I have is certainly stiffer than stock, but way more comfortable than the OME shocks. Highly recommended. Didn't overheat running fully loaded built truck (5 passengers plus gear) at 50 mph over washboard for hours in death valley. They got too hot to touch, but kept performing, and I think there was a lot of margin left.
