A few weeks ago when the weather was nicer I decided to try and get a little more lift out of the rear of my YJ. Since I have Revolver shackles I could not get any shackle lift, but that is what I needed. After pondering for a while I decided to move the shackle point under the frame instead of through the frame. I needed the extra room for the 35" tires and to help level the Jeep. The springs were not sagging, but after all the trail gear was loaded and the new bumper was made it would dip the rear.
I cut a section of some 3x6x3/16 box tubing about 2.5" long (the original material I was going to make the rear bumper from). I then cut it in half to make 2 - 3x3 sections of u-channel. This was perfect and fit tightly over the frame. Since I had poly bushings in the frame I cut the ears off them so they were flush with the frame and also cut the metal sleeve down flush. I then drilled a hole though the u-channel so it could be secured through the original shackle hole. Later on I welded a tab on so it could be secured through the bumper bolt hole on the bottom of the frame. I had already purchased a sleeve and bushing assembly set up from M.O.R.E. (www.mountainoffroad.com) for around $8 each. They put a custom sleeve in it so I could re-use my shackle bolt. Then I cut 2 pieces of .25"x2.5" flat stock about 2.5" long and used a hole saw so the MORE assembly could be slid through them and welded. Then I welded the plates to the u-channel. I put the bushings in and I was done. What I did not realize the first time around was, because of the Revolvers, I had drilled the mounting hole wrong and it cause a bad angle on the Revolver and under compression the spring would contact it. I drilled another hole and it rotated the Revolver up. You can see this in the pics below. This probably would not be a problem with regular shackles. I wound up getting around 1.325" of lit which was about .5" too much, but I am sure with the added trail weight it will be fine. One other note, It did turn the pinion angle up some and I had to decrease the pinion angle by 2*.

The original mounting hole. With the weight of the Jeep on the spring, the spring would hit the Revolver. It is hard to tell with this pic because there is no weight on the springs.
