Ok, I am coming out of the closet here so dont beat me up to bad. I own a 93 Dodge cummins 4x4 that I have added a massive winch bumper to. The front is sagging a bit due to age and the weight. I would like to level it out a bit and have considered the front spacers. First of all, are they really safe to use on a 7300# truck? If so, the dodge Dana 60 has a weird u-bolt and stud arangment to hold the springs down on the diff side. Are 1 inch longer studs available from you? Thanks for any help.
