This is actually a fairly simple concept that has been successfully used to lift H1 Hummers for years.
Remove this:
Lower it:
..and repeat up front.
It's not as easy as it looks but seems to work well. We're still waiting on the long overdue driveshaft before we can finish the project. Might something break? I'll be the first to let you know.
In the meantime there's lot's of other stuff being done. Skid plates, winch, rear bumper, front bumper, etc. I'll have plenty of pictures when it's all done. Be patient, this stuff always takes longer then planned.
