I am looking into a lager lift for my 4 door long bed chevy. I have the standard 6 inch lift for a one ton i just can't find a place that makes one larger. In the rear i'm planning on a shackle flip but what can i do in the front to raise it. I would like all spring lift but for the spring size its hard to find. Can i get the spirngs custom made for a fair price. I have a winch and bumper on front and planning a cummings turbo diesel so i'll need a little heavier rates. Thanks
