Today Frank (71 Gold) and I were talking about rear leaf springs I had noticed that the `72 4 door v-8 Mav I just stripped sat nice and high in the rear ...and His 4 door comet parts car sits up well also. It occured to me that I have Never seen a 4 door with the usual rear end sag that 2 door cars get,and it makes sense that the factory may have used stiffer or higher arched springs on the 4 doors due to the added weight of the rear doors and the greater probability of rear seat passengers(the reason one would have purchased a 4 door in the first place no doubt ) Does anyone know for sure if the springs were different?
my 76 4 door has four leafs and robberts (mavericknutt) 73 4 door has a 3 leafs so ya they even used different springs on the 4 doors
Insight... When I got my leaf springs replaced, I was talking with the shop owner, and his books/computer/et. al. indicated that there were at least four, perhaps even six, types of leaf springs used in Mavs over the years. He did verify that even 4-doors often had different springs from one another. In fact, I still have his contact information: Ron Right Way Spring Co. 2545 Jefferson Ave Tacoma, WA 98402 253/272-4022 (comm) 253/305-0712 (fax) He had to take one of mine out to send to the fabricating facility to make sure that they would create the right one... My Observations, Atzy.
Not only will the srings be different from 2 to 4 door models, but I am reasonably sure that the factory used different springs based on engine application, and perhaps manual vs. automatic transmission. Usually the aftermarket lists a minimum of replacement parts, as they tend to simplify things. I hear that Mustangs from 1965 to 1970 used almost 60 different leaf spring rates.
