    Hello everyone I'm new to the forum and new to older mopars. I'm currently building a 71 Swinger with a slightly modified 340 and 727 trans. The car will be used mainly on the street and a few times a year at the track. My question is what in your opinion is the best leaf spring for me? Pics of your car with spring set up would be greatly appreciated. Thank you.

      My favorite leaf spring I have used so far for is from springs and things @espo.com. I did a 1 inch overbend to raise the rear up a bit. It was very good in the street and launched straight on the track and street. It did sit a little higher than Steve190’s car in the above picture.

      Keep in mind that if the car sits a bit high for you, then you can get lowering blocks to place between the spring and axle tube to drop the rear end of the car down without I’ll effect.

      Sorry, I don’t have a picture.

        Keep this in mind. Dave Dudek runs 9.80s with his stock tire 69 Hemi Roadrunner on standard, low performance 383 Satellite leaf springs.
        What you do with the shocks, tires and front suspension is far more important than which leaf setup you choose.

          Looks great! Hows the overall ride? I'll have to look into them.

          I'm just installing my fourth set of springs from ESPO on Darts from 1970 to 73. High quality product that has never disappointed me. I also ordered mine with an inch or two of extra curve. All the leaf springs settle down after a couple years so unless you want to do this again, I think it's a good idea. Be sure to order the 6 leaf spring for a 340 car!

            I really like the ride it is not hard and the car launches well. I drive mostly street, with some hard runs. A great product and they will help you with questions, very good service

              Thank you for all the help everyone I'm going to take a look at the espo and feel firm springs. I've also seen people running with XHD springs from Mancini racing. What are your thoughts on those? I dont mind springs that are stiff and made to raise the rear. But I also dont want something so stiff itll make me fishtail.... Jersey roads really suck.

              MOPAR SS, 02-03 Springs. Rides good, launches HARD. it the tire that makes it look high. Before the big tires it sat pretty low.

              Tire is 29X10.5X15 Drag radial.
