The front end on my '85 720 4x4 is sagging. Naturaly, I took the truck to a local suspension specialist to have them crank up the torsion bars. They told me that the torsion bars had already been cranked up to the max, and there was nothing I could do but replace the torsion bars. I do not want to do this, however, because it is a very costly fix. I am trying to look into helper springs for independent suspensions utilizing torsion bars. I have heard people say there are helper coils that can go over the shocks, but I have been unsuccesful in finding anything close. I just want to know if there are any helper springs like this available, and if so, where could I get them? Any help or suggestions would be greatly appreciated.
