My ol man has a 98 2500HD, 454, 4l80, 14ff rear, and has a Pro Comp 6" lift with 35s. For whatever reason he bought the truck, now he is bitching about gas mileage. Go figure. He wants to take the lift off and run stock size tires then put a plow on the truck. Looking at it breifly, looks like we should be able to just unbolt the lift to put it back to stock. Is there any reason why it shouldnt just unbolt, or is he pretty much fooked?? He will sellt he lift, and the 35x12.5x18 Cooper STTs on 18x9 chrome Eagles, if anyone is interested.
