Hello i have a 99 single cab sport with a 4.2. I have some 3 inch lowering springs from a lightning. I have heard that since mine is a v6 that it would really only lower it about 2 inches due to the smaller engine is this true? Also how many leaf springs should there be in the leaf pack? Because mine only has 2 and a short one underneath which i believe is the overload spring, it is not straight it also curves with the others.
