Placed the jackstands forward of the wheels and leafsprings where the frame flattens out. I jacked it up so the tires were about an inch off the ground. I installed the shackles first by removing the bottom bolt then jacking up the rear to get the top bolt out. Install was just reversed. I did one side at a time. After I had the shackles on I loosened the u-bolts holding the rear end in place then jacked up the rear to install the shims. Again one side at a time. After everthing was together I tightened everthing up, but not too tight. I then lowered the truck onto the tires and jumped up and down on the rear bumper just to make sure everything was settled then torqued everything down. After my test drive I checked everything again. I guess I should mention that I installed the shims from the front (thinner edge forward) and I used the last hole on the shackles. It got me just about 2 inches exactly and I think it looks much better.

Stevenslow, Your installation is reversed from what the directions state on the Ground Force shackles. Putting in the shims 1st, and then installing the shackles per their directions. Since you were successfull, I guess there is no difference. Did you disconnect the bottom shock bolt. This is on the Ground Force instructions. Just curious. Thanks again for your help. I hope to install mine in a week or so. p/s. Are you happy with the drop, and was it 3" or 2"
