One of my truck's previous owners lowered the front end and the truck still has original tires, the insides are severely worn and showing cords in some areas. When I put my new tires on in spring, is a front end alignment all I will need to assure even tire wear or do I need to do something with the torsion bars at the same time? I would actually like to raise the front end 1/2" back upwards, it's a little too low for me now.
