Alright, built a set of custom 52's. added 2 leaves to each pack. The leaves were from another 52" leaf set. I cut down the leaves 6 1/2" or 3 1/4" off the front & back. The intent was to get rid of the overload & replace the capacity with a more progressive action. They perform about like I had imagined. They are stiffer than a stock 52" spring. The provide some lift, I'd say better than an inch. They handle the rough stuff better than a stock 52. They would be a great lift spring but are not what I am after. Had to give it a shot. I don't hate them. I'll probably run them the way they are till I either replace the springs with ORD springs.
