Leaf spring question for the road race guys...

If you have two left springs they are the less cambered of the two, and I believe have a somewhat lower wheel rate. For road handling this would be preferred over the typical SS installation with the biased springs. Even so, the issue with these springs is their relatively high camber. Spring camber raises the back end of the car which is bad for handling (elevated roll center, increased rear steer, forward weight bias).

The stock Mopar rear geometry had the springs nearly flat which is best for handling. So your best bet would be springs with a stock camber, but an increased wheel rate, such as HD or XHD springs. Next best would be to de-arch what you have now, but beware your shackle may bottom out limiting travel. Third best would be to flip your front hangers which will lower the back of the car, but does nothing to address the camber issue, and may cause grief with pinion angle.
