I've got a set of old, good 5 leafs that I got from JC Whitney-like 25 years ago. They are holding up great, but I'm running 2" drop blocks and flipped hangers to get the ride height that I want. I'm either going to have them de-arched or get new leafs.

Now, will they settle into that over time, I don't know. The last set I picked up did the old, unscientific stand on it and measure deflection test and came out at 180#. But they are flat and will drop ride height. They also have an odd ball 22.5" front segment. You can use SS spring front hangers with them, but it will push the axle back half an inch. I believe ARE sells a oval track spring specific front hanger if you want to maintain original axle position. You could find these at Mancini or Firm Feel.

Firm Feel usually has them in stock since they sell that system as a package with the springs. They sell a lot of the Oval Track spring and hanger setups.

I did the "jounce on the springs and measure the sag" to approx the rate, but my memory ain't what it used to be, IIRC it was 100 lbs/in.

I figured it was just a typo! You know more than me about all this anyway.
