Here's a very informative thread, A new Weight Distribution Hitch (WDH), on the Lance Owners of America forum.
This one has some excellent "engineering" data. :B
Be sure to read the exceptional presentations by Bruce H. who also has contributed to our thread under the same user name.
Bruce has measured, and presented in graph form, the relationship between urethane spring compression and spring load.
His results show 1/4" of compression produces about 1200# of load per spring.

Ron,
Thanks for the link. I fully agree Bruce H.'s report is outstanding!! He is taking the extra steps to totally try and under stand his hitch and we commend him for that. Way to go Bruce!
1/32" = approx 300# of chain force. On his smaller setup these fine adjustments can make a large difference.
It would be interesting to see if that somewhat linear relationship he has seen from 0 to 1,200# of urethane spring force held that constant on a tongue weight of 1000 or 1,400#.
