I always think that in a truck the back should be a bit higher than the front for hauling, not everyone likes that though. Generally the leafs will ride in after a while but too much leaf spring in the back will certainly make the ride worse although my 98 rides pretty bad now and I still have to redo the leafs but I will have the graphite sliders installed, did it on a couple hotrods and it sure made a difference.
OK, dumb question... Do the over load springs curve upwards or downwards?
