Cutting 1" from the springs could actually lower the truck 2"!
This is because of where the spring sits in relation to the length of the swing arm.
The danger of cut springs is that they don't maintain tension under certain conditions and can fall out of the spring mounts at the most inappropriate moments!
Most states deem this practice illegal and will void any insurance if you have or cause an accident.
An old trick we used to do was find a set of springs out of a six cylinder model and fit them to our V8 models, which gave us a drop in ride height and a smoother ride for no cost at all!
Get a proper re-set pair fitted specific to the ride hight you want and weight of your truck.
