Dumb question... Probably not related the the OP's post, but does the location of the front spring eyelet, on other words angle of the front leaf segment to the ground or chassis, have an affect on axle rotation with a cal trac?
I'm know with a ladder bar car lowering the front heim into a lower adjustment hole Softens the hit on the tire, and vise versa, raising the heim attachment makes it more violent on the tire
Yes it makes a difference if the spring eye is higher or lower.. that is the IC.. on a leaf you cant cant the IC length(unless you change the length of the spring)but you can change the height... just like a ladder bar... but it can change if the spring is rapping up
