Rear leaf springs and shocks

It totally depends on what you’re planning on doing with your car, road racing, drag racing, cruising or whatever. I know of road race Abody cars that are use two right side SS springs and they work well, I know of a Abody drag car that has tried both Abody and the heavier Bbody SS springs and stayed with the heavier ones and I know of several others who use the Abody SS springs for their drivers. Then there’s others that say not to use them at all.
