Not sure if this makes sense but I have had my lift on for a few years and as everybodys does, it has sagged with the addition of weight. Im gonna be adding a 4x4labs bumper so I have decided to get the long add a leafs and wanting to rearch my springs. I called a local spring shop that will do it and they wanted to know how much I wanted them arched? Well it was a 3" lift and I figure they have lost about 1". So do I just tell them re arch 1"? I dont know the specifics of re arching but Im assuming thats all I could do right? Just dont want to mess anything up. What do you think?
