Yeah, well I actually found OME at least online. I cant find Ironman though, I need to do research again. I'm actually running factory torsion bars, with rancho 9000xl shock, the top shock for mits by rancho. Suspension is very comfortable with this set up, even with the big 35 inch tires, it has a dial to adjust firmness from 1-9, 1 being the softest and 9 the hardest, right now its a 3, but after 2 hour drive, I feel these bars fatigue. I'm going with the upgrade anyway, I'll put a review of which I buy and how they feel and perform. I have seen torsion bar upgrades on a dodge ram pick a friend of mine has, and the difference is very notable, the bar is thicker, and the ride is much more like when new. he had factory with 37 inch tires, it was horrible to drive, now if feels like a brand new truck.
