Hello, I wonder if anyone has done a spring swap on a Roadmaster. I am thinking about using the moog 9c1 replacements on my Roadmaster to (1) take care of a saging issue on the pass side and (2) give me a little more clearance in front as well as a more progressive rate. At speeds even with new shocks it can get squirrely. I think the springs are the moog 5030's. I have new shocks but I got the sensatrac instead of the sever dutys(mistake)so may fix that too!! Thanks for any insight.
