    Hey folks,
    A friend told me that the Road Runners have different rear leaf springs (Super Stock I think he said they were called) in order to counteract torque under hard acceleration.
    So I looked under the car today and sure enough, I counted a 7 leaf spring on driver and 5 on the passenger. I counted a couple times so I think this is right. But something tells me they should be reversed in their position. Like the 7 spring should be passenger and the 5 on the driver side.
    Does any of this make any sense. . . ?

    Good question, would say maybe driver side under normal hi-stress would be the wheel with the higher gripping torque? Chrysler engineers were ahead of their time back then. Traction bars were awesome, had chrome set on my ‘Lil Red Truck. Definitely period correct but never see any in photos of road runners? https://www.bing.com/images/search?q=traction+bar&qpvt=traction+bar&FORM=IGRE

    yes, larger spring belongs on passenger side to counteract torque on launch
