I was looking for a pair of SS Springs on Mancini Racing's site...There's a bunch of different ones with different weights... I weighed the 69 Dart and it was at 3240 so thinking the Duster may be a little heavier at 3300 or so. The springs are for a 72 Duster with a 416 and a 727. 8 3/4 rear and 4.56 gears. Which one would be the best to use? 3300 lb springs #MOP 865-866 or something different???

I've always ran the 456/457 B-Body springs on my stuff. Worked fine. Matt beat me to it. This is what we used in a '72 Duster with a small block. Plants the tires hard,lots of extension, but it rides a little stiff in a street car.

When we put the Dart together I had swapped the front perches upside down in it to lower the ride height too. The rear is a 65 B Body 8 3/4 that I mocked up to use for the 69 but it was just a little too wide. I just ordered the 002-003 but by the looks of things I'm not sure it matters a lot. Most of you guys in this thread are running faster than this ever will... Thx all...

I used to have the 002/003's in my Duster but man it was violent. I had a friend video the launch one time and you could actually see it lifting the left rear tire off the ground while both front tires were off the ground as well. I decided to ditch them and went with CalTacs used their mono leafs and adjustable shocks. Didn't make the car any faster but it calmed it down considerably and made it way more consistent. Car ran mid tens.

Is this a track only car or a street car? I'm running two passenger side 2800lbs SS springs in bith my 3700lbs A-Body and similar weight E-body. They are the perfect spring rate for street use.
For a track only car, I would have used the specific left & right side springs to flatten out the body lean on hard launch.

Unless you strip a bunch of weight out of the Dart the Duster should be lighter than the Dart I've owned, built and race both, several different Dusters and all of them where lighter than my 1969 Dart GTS BB car stripped of the heater, radio and seats, it had a five point NHRA legal chrome moly bar in it with stock leaf springs and later the Mopar brand SS 002, 003 leaf springs It did have a all iron 440 motor with a 727 and 8 3/4 in it back then also

002 AND 003 if you do something silly like "lower" the high side etc you just ruined all of the research and development that Chrysler put into those items--it was extensive and cost a wad back in the day--They sit the way they sit so the car will LAUNCH correctly--change it so it "looks" better and you ruined it. Super stock springs rely on the correct shocks to work right--they are designed for DRAG cars so the shocks that work on drag cars are dangerous on the street You need something like Koni SPA-1's on the front set to full loose and some serious adjustables on the back NOT Ranchos etc Most stock guys now run the Caltracs but they are harsh on the street McCandless ALWAYS insisted on 002 003 on an A Body They WORK !!!!

Define ruined. I just beat a Hellcat in a flag drop drag race with a 410 hp EFI'd 408 Magnum while running a pair of driver's side SS springs and Koni's all the way around set-up for open road handling. Could my car be even quicker out of the hole for drag only use set-up with the original staggered spring rates, drag only shocks, and a pinion snubber. I'm sure by a few 10ths, but the trade off for the average person in drivability, ride quality, looks and overall performance is hardly worth paying for a negligable reduction in straight line launch times. I'm just saying that a person has to use their own judgment and do some experimentation to find what works best for them. That's what Bob Tarrozi explained to me that he did when he spec'd out the SS springs and a pinion snubber they used on the Hemi cars of the late 60's.

I had a best 1.36 60 ft. with a set of 002/003 SS springs with 2 in. lowering blocks. They were on a Stock interior 72 Demon with a 360 on 100 shot NOS.

Well I have put SS springs on many cars and you cant leave it sitting as it is on some since they sit so far off level. I adjust the torsion bars to get the cars close to level and had never had a problem. I wont drive down the road with a car 4 inches high on one side then the other and they have all still hooked fine. I had to adjust the bars on my 63 after installing 3400 lb SS springs and it hooks great. I also dont use any special shocks as all I have in the back is the longer MP shocks that are basically a normal shock that extends farther. I did put a set of 90/10's up front and they work fine on the street as I drive it all the time on the street since my car is a 99% street car. Here is a pic of my sons Dart with the 002 & 003 SS springs and this is how it sits after installing the SS springs and me adjusting the torsion bars so it sits close to level. Ron

Ron I did the same. 456 and 457 springs on my '63 Dodge. I leveled it out and used CE 90/10 front shocks with the upper control arm bumper removed. Best of 1.60 60 ft. with 275'a so far but I have yet to race on a really good and warm prepped track. As far as ride, it rides really nice! I figured it would be stiff but it's not! The car drives great on the street but I don't take corners fast with /6 torsion bars and no sway bar! I couldn't be happier with it on the street.

I had 003's on both sides on a 65 dart (came to me that way as a roller) & they were great, it rode high and tight, daily driver. not sure if the 002 and 003 have a different height or a different rate (or both) but I'd look into that if that is a concern. EDIT I had 14's on there & it definitely was not jacked up from how the wheels looked but shock extensions were neeed

Even though I did something silly like "lowering" the high side by flipping the front hangers over if you look at the attached log sheet of a day at the track for the Duster and specifically at the 60 foot times for that day I think you might agree that it really didn't affect it. I know it's not a fast car but I think the repeat-ability in the 60 foot is "pretty" good. This is with the long Mopar shocks on the back with 255/60/15 MT ET street's and CE adjustables on the front with 6 cyl. with ac torsion bars. The second picture has the 2 best timeslips for the Duster. The 60 foot times on those aren't too bad either. The third picture is my Valiant that the springs were originally in. It seems like that car was working pretty good too. If Chrysler didn't want you to lower the front of the spring why did they make and sell adjustable front hangers through Direct Connection. Some say that lowering the front of the spring flattens it and increases the stiffness in the front segment. That may help some and hurt others but until you try it you won't know. To say that all Chryslers research has been ruined is silly. They were the KING's of trying different things.
