shock mounts weren't designed to actually carry vehicle load full time. when we bought my duster in 1991, it had 50k miles and I can't remember now if it was those coil over shocks or air shocks on it. both shock mounts were completely ripped out of the unibody.you want to get the butt in the air a little more? either new springs, re-arched springs, add a leaf or even go with longer shackles to get a little more height.
