Ok I am sure this has been asked a million times but what is the general rule with lowering a coil spring truck to maintain close to level is it like 3 inch drop in front and 5 in the back ???? I want to bring my 69 down cause it looks more like a 4x4 than a 2x4. so I just wanna know whats the math is on all this cause I can,t see it being equal drop all around if you go with lets say 3 inch drop front and rear

yeah, generally 2 inches more drop in back gets it level.

This is my old truck. 3" drop in the back. Stock height up front.
It sat level. It's in Langely now.
