Ok I bought my shop manual like someone suggested but it doesnt help me with lowering.

What is the best way? I read on dropped axles but is this in some way better than dropped springs? I have been looking at the dropped spring kits from Orange Co F-100 catalog (which by the way I dont know if these kits fit on a 250 or not). Best to drop front 3" and back 5"

Again thanks for the advice and help..its always appreciated.

 

A dropped axle is the easiest way to get a three inch drop in the front without affecting travel or removing spring leaves. You can get 2-3 inches removing leaves but suspension travel will suffer. To get 5 inches in the rear you will probably need to move your axle to the top of the springs and C-notch the frame.
