"Another method of reducing tramp is to add a thick leaf on top of the front section only of the leaf pack. I have read about people getting another top leaf (as in the one with the leaf eye), cutting the eye off, cutting the leaf off behind the U bolt, and attaching this above the original top leaf, to good effect"
I asked a spring place about this and he said that in 20 years of redoing springs he had not heard of this, maybe its just him (was kinda of thinking that I should talk to another spring shop).
