I just installed new shock mounts on our "light duty" 1 ton K5. It came to us with Jeep style shock mounts welded onto the frame (basically, just strap stock with a stud sticking up about 4" over the frame rail). Somehow /forums/images/graemlins/rolleyes.gif my son managed to rip one off driving on the street (hasn't been off road in "forever") and bent the other near 90*. Must have been curb wheeling at the mall... <sigh> Anyway, I got a pair of cast steel SD shock towers and mounted them up last night. I must say I like them MUCH better than the stamped steel Ford towers that have become so popular. No idea what they would cost new, but I got these free from a 4x4 shop that was going to throw them out after installing a lift and shock loop on a new SD... Anyone else done this?
