I would like to lower my all stock 65 C10. Right now the distance from the ground to the bottom of the front bumper is 14 in and 19 in the rear. To me this is just way too out of wack ! Will probably do it with springs but just not sure the best way to go. So heres some of my questions if anyone has any suggestions.

If I were to just lower the back 4 inches to make it a little me even, would it cause any problems in any areas, drive line etc ? Also what parts do I need other than the springs ?

Thanks, Billy
