Not much to it RJ, you just need to release the upper ball joint (with jack under the lower control arm), undo the shock from the top then lower the jack to release the spring tension. The shock can then be detached from the lower control arm (it's obvious) and changed. Sometimes you need to smack the upper ball joint mount a little to get it to release.

Make sure the lowering springs have a reasonable spring rate. Dale had trouble with his lowering springs as they were pretty soft. The Bils are harder to install than the springs (the rears springs are super easy, drop the retaining straps, lower the diff, and yank them out). The shocks are very stiff and hard to get installed - it takes a fair bit of speed to get them in. I first compress the shocks as much as I can by hand and very quickly set them in place. If they rebound too fast, you'll have to struggle with them. They are definitely not like the stockers that can be installed without trouble.
