Bending Leafs for Ride Height

[astroracer]

Wendell is exactly right here... The REASON you don't want to do this is; Leaf springs are made from tempered steel (spring steel) and, as soon as you put a torch to them to "rebend" them, they will lose all of their temper and springiness in the area you have heated. This will lead to broken leafs in a very short time which will not be good... This is nothing to be done at home. Take W's advice and go to a spring shop to have then re-arched...
