Rear Leaf Springs - OE or Competition - Super Stock? - 12/26/17 09:25 PM
What type of rear leaf springs did you install on your Mopar? Mopar offers XHD Lead Springs - OE (P4510268 & P4510269 for A-Body) or Competition - Super Stock (P3412002 & P3412003 for A-Body). Just looking for feedback on why you selected the spring and primary vehicle usage.
Can you use Super Stock Springs in Pure Stock?

I had 002/003 SS on a 65 SB dart (came that way as a roller) & it rode high and tight when done (daily driver). I was happy with em.

I run oval track springs
https://www.summitracing.com/parts/DCC-4529414/Mopar offers more than the two choices you mention and if you don't mine aftermarket AFCO makes a bunch more choices.
I run them because the spring rate works for me and I do not like poor handling of the jacked up butt look.

I put 002-003 springs on a 71 duster w/500" 440 and also had the adjustable snubber too. It was just a little high in the rear so I put 1" blocks back there to lower it a hair. Worked out well, went 11.20 and was mostly on the street.

I used the 456/457 MP SS springs. They lost their arch and quit working after about a year. They did work well to begin with but started wrapping up horribly.
I went with Cal-Trac split mono's and happy so far! The car wanted completely different torsion bar setting and leaves smooth and level now.

Which shocks did you go with?

On my (low powered) ‘73 Duster I went with springs and things 1 inch over bent units. These were very much a capable HD spring. Road, drove and handled very well. Launched straight as an arrow. Very pleased. The power was under 400hp. Just a good running toy.
On my ‘70 Duster, I am switching from springs I had in my E body. There the 3600lbs. 460/461 springs. Good in the E body, not so good in the A body. Which is getting lightened. I now have the 863/864 - 2800lbs. springs in there. Yet to test.

I went with XHD on an E set up for handling. They tend to be low which is a good thing in my application. The bias design helps (in theory) coming out of the slow corners. As I got the car sorted, rear spring rate was a little low and the XHD sagged. My local shop added a full leaf for $100. Spring rate and height are just about right now.

since it was a DD I used some cheap parts house A body length ones that I already had on hand & they needed shock extensions which I also happened to have some in my stash. sometimes things go the right way. I shoulda kept it.
