with the A-body 8 3/4 floped on top of springs and a shackle flip I used a set of A-body liftbars from SSM.

they are an old skool traction bar that replaces the the shock plate and clamps the end of bar to the leaf springs.

it has wedges to use to pre-load them or one side more than the other.

I liked them on my truck, it would hook off the line and lift the rear end of truck a couple inches planting the tires for traction.

I have them on the shelf for now. will be adding coilovers soon on mine.
