John,
as you probably already know, Mark's Off Road is now a distributor for Ironman Suspension products for 40, 60, and 80 series Land Cruisers.
I stopped by his shop last week and he was unloading a new pallet of Ironman products, and since I have extra-heavy OMEs on my truck, I wanted to compare them to the equivalent Ironman setup.
I wish I had taken pictures, because I was very impressed with the Ironman setup and build quality. The rears have 10 leaves, including overload, and the overloads are noticeably thicker than the OME. Energy suspension bushings fit perfectly, so you wouldn't have to use those $$$ OME bushings.
Mike (Biscuit) installed some on his 40 last Saturday and he's very happy with them. He says all the sway and steering play he had before is gone, even at highway speeds.
If the Ironman were available when I was in the market, I probably would have gone that way, mainly because of cost and shipping considerations, and the Ironman springs just look super beefy. I'll see if Mark has any pix and I'll post them.
And, if you get them before SnT, I'm sure Mark or I could MUD ship 'em and save you $$$ in shipping.
