I'm not sure what material the Magnum Force spindle/knuckles are made from, but beware: A buddy of mine has them on his 71 Challenger and wheel bearing failures caused excessive wear to the spindle portion. He said a groove formed approx 1/3 of the way through the spindle. I agree that stiffer T bars plus a modest 1 inch to 1.25 drop is a far better idea.
