Leaf spring selection!
« on: December 12, 2009, 05:21:32 AM »

     I was wondering what sort of leaf springs I'll be needing for my 1972 Dart.  The car has a 440 / 727 combo in it, but other than that it is not heavily modified.  I want the car to have some rake to it, but nothing too dramatic (I should mention that I have 1" torsion bars up front, if that makes any difference).  Which ones should I choose?  Does anyone have any recommendations?

OEM 6 leaf HD springs are nice for the street. i had these on my duster and it gave it a nice stance. go with adjustable  rear hangers so you can lower or raise to your taste.

Before I went with a Caltrac setup, I had ESPO (Springs n things), 1" over stock ride height on my 68 Dart.  Not stiff, and a decent "rake".  The pic below is just after I installed them.  They did settle down to the advertised 1" lift after alittle street use.

Excellent price, and even better customer service.  Thumbsup

You ain't gonna believe this, but JC Whitney has AMERICAN made (JR Springs in Illinois) for only $65 bucks apiece. They come in stock or 2" increased lift or stock. I running the stock and as you can see, there is still a bit of rake.

i heard that they lower the car one inch or more. and they use the bigger 5/8 front eye bolt and the bigger bolt for the rear shackles so there suppose to be real sturdy. plus im using adjustable front hangers so i can go real low in the back  !nanr

               That's nuts!  If they're even somewhat durable that may be a good deal.  How much was it to ship them?

I couldn't wait for an answer, so I checked the site.  According to the website itself, they do not have them for my '72 Dart.  It could be a web snafu.  When did you buy them?  Do you still have a part #, or do our vehicles not take the same springs?  I'd be a bit surprised if they didn't.

Right now, Whitney is offering free shipping on any order over $75.. And yes they still make them, but you may have to call them because it's so old of an application. I bought mine 2 years ago  for $57. each! !nanr

I did some homework for you (using my car). They also offer a money back guarantee, no questions asked!
Here's the link for the stock springs

Thank you for that!  Our cars take the same springs?  That makes thing easier.  I'll get right on that!  What would I pay for some adjustable shackles?

I think with the arc you're going to have, you won't need adjustable shackles. They're usually a band-aid for sagging springs anyway. I'm sure you can get them at Whitney's too if you really want them

We used the MP 002/003 springs on my boys Dart.  You can see here how it sits.   Even if your car sits high when you put springs on it you can lower it some with lowering blocks.    Ron

There are very stiff yet flexible from one wheel to the other only when the tires meet uneven pavement, soon to have a nice set of shocks and a FFI rear sway bar.

I had heard this before and I went to thier site and searched up and down and could not locate these springs.   Is there a part number Huh?

SS springs suck for street use, rear end way too high. lowering blocks way too low, the ride is harsh and noisy. Had a set on a 72 duster after about 300 miles they came off the car for some nive ESPO springs that are perfect for street and occasional strip use. Heard some good things about the JC Whitney sprins on another board, could be worth considering.

I'm wanting to get rid of the shackles on my 68 Dart. Never really liked them. I like the looks of Codfishes 68 clean, nothing hanging out or down.
i like the Darts that are alittle high in front and a little higher in back. Kinda the crouching tiger look. Codfish ya got it right.

SS springs on my 63 in this pic.  This is just how it sits when I put them on and have the longer extending C-body shocks.  They ride great for me as I drive it everywhere.    Ron

       Those are a pair of sweet machines.  You must be proud!  That looks like a good stance to me, though I may not go with the SS springs.....unless I order 2 which are for the same side of the car (an uneven stance would drive me nuts).  Oh, and can you use C-body shocks on, say, a '72 or '73 A-body?  What C-body years will have compatible shocks?  I know they are longer, but what will be the advantage of this?
        I ask because I have a pair of coil-over load-bearing shocks on my C-body (I added them because the dual exhaust sits a bit low) and I'm really happy with them.  I'd love to put a set of them on my Dart.

Thanks for the kind words.  The black 65 is my buddies car and it is nice.   Thumbsup   The C-body shocks have longer extension to them so they wont top out when the SS springs work on launch.   
The springs I ordered from Mancini and they are their 3400 lb SS springs that came with new shackle's and bushings and new U-Bolts.  It did not sit perfeclty even but I just had to adjust the torsion bars as you do almost any time you install SS springs on a car.  I love them as it drives great and they work nice at the track.  In fact the last time out with the car in Oct I was driving the 45 miles to the track when an SRT-8 Challenger started messing with me in a small town I was driving thru.  I decided as we caught the last redlite in the town I would go.    I spanked him but his car ran good as I use 30lbs in my rear tires street driving and I spun when we took off.  He had a car lenth on me before I got a bit of traction easing out of it.  I wound out first and got dead even with him when I pulled second and put 2 car lenths on him  When I was ready to pull third around 90 mph I lifted as he did as we knew who had won.   He was probably a good mid 12 car.  Then at the track I ran my best of 11.49 and ran a 1.57 sixty ft which I felt was good for a mid 11 car.   Then I drove the 45 miles home.   Smiley   But I feel the springs work very good as it launches nice and straight now and the car stays very even from side to side.  I dont have any real good launch pics of it with the new sprigs but I have this pic as you can tell its nice and straight.     Ron

Here is a launch pic before the new springs were on it. It would actually get worse then this as when it hooked before the new springs it would lift the left front wheel 4 to 6 inches and the right front wheel was still on the ground !  Ron

Nice stance. haven't gotten into the suspension on my dart yet. i know the shackles will have to go. Thinking about checking out J. C. Whitney.
Going to look at front end also. dart seems to handle extra weight of the 354 pretty well . Good set of shocks wouldn't hurt.
