First off, I have to say I really like the truck!

But, I would ask... Whiskey Tango Foxtrot was wrong with the original springs? Sat too high?

One thing about the A-body rear leafs is that the front section is short - really short.

Putting a slapper bar on that spring is going to try and lift the vehicle at the front spring eye of the rear spring. I would imagine that a system that would try and lift up the chassis at a point further forward would tend to lift the entire vehicle, instead of just picking the back end up. Hopefully putting a little more weight on the rear tires while it's lifting.

Unfortunately, my project has been stalled by a move across country, a career change, and a home purchase.

So, I'm gonna' have to subscribe to this thread and live vicariously...
