Never had on a Mopar. On a Chevy they worked somewhat.
But it's old technology. I've done very well with SS springs and a snuber for pinion support on a 10 sec 3000lb Duster.
I believe once your build gets into the 9s and faster where chassis certs and licensing becomes more apparent? Then a ladder or 4-link systems become more of a survival necessity.
