That something, is the Direct Connection Leaf Link! I am in the process of putting a Dana 60 in the Aspen that I bought from Andre over in Michigan (68shifter) which is a great looking piece, and it was a great price. Good guy to deal with! Anyway, we have yanked the old stock 8-3/4 with 3.23 gears out this past Saturday. This week I will finalize the brackets, and with any luck, get them water jet cut at work.

After attending one of Dave Morgan's Seminars www.davemorganseminars.com I think I will change the leaf link design slightly. It's hard to explain with out pictures, but I will be moving the bottom mount for the diff above the leaf spring, instead of below the spring like the original design. I will be contacting Dave once I have everything drawn up to see what he thinks. When I talked to him about it at the seminar, he thought the leaf link was a great idea that just didn't get enough use. The four links came and that was the end of that.

Why am I doing this instead of Cal Tracs? I would like to try something different, and I think the leaf link is a neat part of the Mopar history. There is nothing wrong with Cal Tracs, their success speaks for themselves. There is also some class races around here that would knock me up a class if I put a ladder bar or 4 link in the car. I think I will be able to claim stock suspension with the leaf link. It is still using the factory suspension, just in a different way.

So, I will try to get pictures along the way, and let you guys know weather it works or not! I think there is a few guys out there using it with success.

What do you guys think??

If it works maybe I will start selling a kit?? As it is now, I will probably do two sets while I'm at it.

Do you know of a URL or drawing that would help me remember what a "leaf link" suspension is?

Big Cube, I don't, but it's in a DC book at the shop. I will try to upload a picture of it later today. I feel the original design points the bottom "bar" (drawing a line between the lower mount of the diff, and the leaf spring front eye) to far up. Moving this pions above the leaf will flatten the bottom "bar" out, more like a more modern 4 link.

Correct me if I'm wrong, but I thought Jegs or Summit sold the kit? Or are you looking at making something different?

Well since I haven't seen a direct connection catalog since the late 70's or early 80's if you can scan a pic it would be helpful. My opinion on most of the old tricks is they are phased out for a reason, if they really worked, people would still be using them. But it never hurts to try to start with an old idea and make it better.

It's a different system, and commonly gets mistaken for it. Your thinking of a kit that lets the axle slide on the leaf, and allows you to ladder bar a car without the use of coil overs.

I have an old DC book at home, early 70's I think, I'll look for it and see if I can find the diagram.

Take some pictures.
My opinion is that the Calvert and the leaf link are the same concept just different locations.

Yeah, I can see what you mean, some of the classes that I like to run locally will bump me up for a ladder bar or four link. So, Cal Tracs are what most will run. The theory behind the leaf link, will give more adjustment than caltracs, and allow me to move the instant center into a better position. I think the leaf link was phased out more because of the rules changing, than weather or not it worked. HOWEVER, that doesn't mean it will work. I am a willing test subject though

Hmm, interesting. I would like to see pics of it, not because I want to do it but I like different.

I agree,Kenny!...dare to be DIFFERENT! Best of luck with your "experiment"! BTW..have you had time to work on the valley plate for the RPM's??? Maybe my price range made you re-think the idea!???

There it is! That as the lower point, below the leaf, where as I will be putting it above the leaf.

Haven't been able to touch it yet, those super stock seat brackets kept me pretty busy when I wasn't at work. I can move on to the valley plate soon, I have to anil down these Leaf Link brackets first since my car is sitting on someone else's hoist with no rear end currently

I have your custom Gold Leaf Plymouth decals collecting dust. LOL. We need to hammer out the other decals you want and ship em out too. Thanks buddy!

For a little back story, The last passes I made with the car was using bone stock suspension basically. factory original shocks, factory Aspen springs using a stiff over load spring clamped to the front segment of the spring. The car had the 3.23 gears, and the tire was a 27 x 10.5 ET Street. This netted a 1.55 sixty foot, and a 10.68 @ 128mph. The car isn't picking the wheels currently.

The changes being made:

Leaf Link
Dana 60 with 4.10's
MT ET Drag 9 x 29.5
QA1 A-Body Stocker "R" front single adjustibles
QA1 Proma Star custom mount rear shocks (a coil over shock with out a coil)
I am already using a set of Afco sliders in place of the factory shackles.

Here is the best launch photo with the old set up. It usually ran a 1.59-1.60 with one 1.55.

OK, so if I understanding this correctly the horizontal bolt though the leaf spring bracket goes through the lower brackets welded to the axle housing. The upper bars connect to some other bracket on the chassis(floor). Your mod is to move the leaf spring bracket to the top of the spring instead of the bottom. (for lower ride height?) The thing that would concern me is how much the pinion angle will change due to non-equal arcs. The other concern is how strong the new axle brackets are but I'm sure some of those concerns could be mitigated with bracket design. Will be interesting to see how it works for you.

There were two inherent "problems" with the original leaf link.
First clamping the spring solid to the pivot created a bind, you could ease that by having the spring slide in the pivot. Second issue was even with ss prings it would kill the spring at the front eye very quickly. Calvert addresses this with their monos being much thicker than even the old made in Canada ss springs. Despite these correctable shortcomings they did work but were shelved when Jenkins tilted the playing field when he debuted his Vega

I'm not much of a drag race historian, are you talking about the 72 grumpys toy car, the one that kicked everybody's butt and staged crooked to run straight? 9.60s?

What happened after that? Did mopar come back after another rule change or something? They outlawed the hemi colts etc, right?

I love the 70's stuff!

You pretty much have the idea. The change I am making with the lower diff mount will affect ride hieght, but this isn't why I am doing it. Moving this mounting point up above the spring, will change where the bottom "bar" points to. With the mount below the leaf, this angles the bottom "bar" in an upward direction too much. It would probably put my instant center somewhere about the middle or lower part of my back when I am sitting in the car. Moving this point above the spring will put my instant center in a more conventional 4 link spot, somewhere around the back of the engine. Also, I think this position will act on the leaf spring similar how the perch acts on the leaf spring, being in a similar spot to where a perch would be. It shouldn't kill the spring as quickly. In the old design, that bottom mount is further away from the leaf. Being farther away from the leaf will tend to want to bend the leaf more. Of course, this is still all a theory. Regardless, if it works, or if it puts me in the wall, it will be caught on video!

I have not been able to post up any pictures yet, as I was quite busy last night. I will see what I can do today.

I don't think this is why Calvert has done a thick mono leaf. If you put a true leaf spring car on a four corner scale, then drive it around the block, and put it back on the scales, your readings will be different. Leafs bind on each other. The mono leaf is a more constant spring. When the Caltracs are under load, those monos are in tension. In the leaf link, the leaf is unfortunately in compression.

So basically the leaf spring becomes the lower bar of a four link. That is going to be in compression then as stated earlier. I can see where that would cause a lot of stress on the spring.

Exactly, that is why DC recommended S/S springs and also to clamp the front segment extensively. It will still kill the spring close to the front eye quite quickly.

Yup, those are the diagrams! Here are some updated pictures. Things that are still left to do are the top bars, shock mounting kit, and lastly will be brake lines. Then we will move on to retro fitting a QA1 A Body front shock into this goofy FJM front suspension.

Nice fab work and welds. The only issue I can see is with the front of the spring and top bar having different radius there will be some rocking of the rear when the suspension moves. I would be worried about that rocking motion loosening up the bolt that ties the spring perch.

Thanks Bigcube, I can't take credit for the welding and fab skills, that would be a couple of my buddies with the welding skills, one owns the green demon in the back ground of some pictures.

The bolt your referring too is my lower mount correct? That will have a lock nut on it. None of the GM G bodies or fox body mustangs have equal length top and bottom bars. Is it a compromise for what I'm doing? For sure! But I think it can still be made to work.

I think I came up with an idea for saving the front spring segment! Stay tuned, should be finishing things off in the next week or two!

I was able to get some more measurements off the car for the final rear pieces to get cut and bent up. I had a chromoly cross member bent up to mount off of for the top links to hook to. After measure up on the rear end of the car we started hacking and chopping the front of car up to fit the front QA1's. The stock shocks in an FJM Body are too short for shock companies to build a truely adjustable front shock. There isn't enough room to put the valving in the shock body. I will have to get some pictures next time I'm out there.

ThIngs are getting tight in the back end haha! It should look about right though in my opinion when it's sitting on the ground.

Alright, we were able to spend a little more time on the rear suspension yesterday. We built the upper shock mount cross member and got everything tacked in place.

First: more power to you, and anyone else who tries to improvise.

My knowledge of suspension tuning is very slight. What I can offer is a prediction of how sanctioning bodies deal with innovation.

1. if you mail them a diagram and explanation and ask for a ruling, they will not give you legal status in writing
2. personal and phone conversations never took place, didn't go the way you said etc.
3. the tech line is only concerned with safety rules - not legality
4. being permitted to race doesn't mean that they agree that you're legal
5. nothing will happen until you beat someone important/influential - you know, the guys married to Force's cousin, blah
6. when protested you fail

The reason given may take various forms as to language, beginning by simply stating the "it's not in the rules" (actual non-compliance). Your objection that it's not prohibited will be met with "it violates the spirit of the rule" (translation: we don't like you).
The underlying reason is simple: you beat someone more important than you.
IMHO it's not legal, in that you're not using the suspension in a different way. It would fail an objection based on patentable engineering features (not enough commonality with OEM).
There are 2 main points of difference:
1. the original leaf was both the entire suspension and the locator for the axle, now it's not
2. a new part has assumed some of the original function, which is not stock

I am betting it will work great if two areas are addressed? Strength of the front half of the lower leaf. Stiffening it with another leaf that goes all the way to the spring eye may do the trick, but never tried it. The other thing on my mind is freedom of spring rate. If the shackles are too short or at the wrong angles, things get goofy. I am betting if these items are addressed, along with instant center being adjustable it should work like a four link.

Polyspheric, I get where your coming from, and if they do come down on me saying its not stock suspension, I won't be bummed out too much.

The leaf spring is still my axle locator. I've just added a pivot point.

Your second point, a new part has assumed part of original function..... That is true. Like caltracs, or "anti-hop" mounts for a GM G-body, or slapper bars even.

The organizers of the few events that could have an issue with it, know what I am doing. Their usual response is "Oh, cool, it's like Caltracs, just not under the axle." I say, "Yeah, sure if you want to look at it like that."

What you are saying about someone more important than me is probably spot on though haha. It isn't an issue until it is an advantage.

Gregsdart, I'm not changing my leafs at all. I was going to try and find a way to do what your saying, but I came up with something else. Hard to explain in words, so when I move on to that part, I will be posting pictures up and it will make more sense.

Thanks Randy, hopefully the "outside the box" thinking works. If not I Am wasting my money!

Gregsdart, I forgot to mention, I am not using the factory shackle, but rather an Afco slider. I put them in the car last year, and it seems to work well.

Here are the rules we came up with years ago when I was still part of the car club. All of our heads up events around this area have adopted these rules for the most part.

This isn't the most up to date picture, but here is a picture with the upper bar mount cross member tacked in place. The lugs are hanging upside down in the picture. Everything that is pictured here is welded up in place now...

Alright, was able to make some head way tonight. All of the rear suspension is fabbed up. Only thing left is to thread my upper bars, and build my brake lines. I threw a coat of black paint on everything to protect it. It looks worse in the pictures. Lol.



We have added a lower bar above the leaf spring to let the leaf spring live.

If it works as you expect a mono leaf spring would be my next change.

Thanks guys, glad to hear other people like like what I'm doing I currently have my leaf spring sliders mounted flat against the frame of the car. I want to be able to run a lower hole in the bottom diff mount and right now it has to be in the highest hole. So I am going to space my leaf spring slider up to raise the car back up a bit.

As for the mono leaf, yeah it wouldnt hurt.

Kenny I would suggest slotting the front mount on the bar above the spring to avoid a bind when the spring de-arches and thus changes it's effective length.

Yeah, I was thinking the same thing. I will set it on the ground and see if it binds as is. I have a big mushy oval front bushing in my leafs, and they have a lot of give to them.

Well, it's been hard findning time to work on the car, but we are getting closer and closer. Hoping to run the car June 8-9 at a local street car heads up, P2P, but my pass track record isn't that great I usually don't have my car together. The rear is pretty much done now though. I need to do brake lines and space my leaf spring sliders up off the frame.

Here are some progress pictures. The bars are threaded, and complete.







Probably the worlds shortest top link bar haha. Will it work? Who knows! But I plan to find out!

Had almost that exact set-up with the bar above the leafs on my '70 Cuda from way back in the day with super stock springs that never sat level. Pretty cool. I switched it out for Caltracs and mono leafs... keep up the good work.

Thanks for sharing pictures! How long of a top bar were you able to sneak in there? I know mine are short, but looking at the fox body stuff, they don't seem so bad, and mine are straight in the car. The triangulation of the fox body stuff shortens the length of the bar parallel to the chassis. I'm not sure what the fox body upper bar length is yet, but if we assume they are 10" long, using good old trigonometry, that gives us an effective length of 8.66" parallel to the chassis.

Sorry I would have to measure it when I get home, I cut a lot of that stuff out of the car when I redid the rear because of issues with the leafs, but there is probably enough left to measure it center to center....

Dragula, did your top bar mount to the car in the holes behind the front spring mount? If so, I can see why it may have not worked very well. That would bring the instant center even closer to the diff than a regular leaf spring suspension would. If this is the case, I would guess your top bar length is around the 16-18” mark looking at those pictures.

Yes. For what it was originally for, I will bet it worked fine. For the Hp I was making, it could be a handfull.

Took the car out for the first test drive down the high way tonight! Everything suspension wise feels great. The way the bars are set right now, it squats nicely, and the front is rising up well. Unfortunelty, as I suspected, the tranny is in need of a rebuild though. I forgot to wire the kick down lever open last year, and high gear is in tough shape. Big mushy shift on the 2-3 shift. Hopefully I can get that sorted out next week. Here are some pictures of how it sits now. Should have track results in a week if all goes well.

Well, The tranny is coming out today, and getting rebuilt early next week. Since it will be out of the car, why not add a trans brake to the equation? Then back in the car for the weekend to test it all out at a heads up street car event. It's only money right?

Thanks guys, it finally sits the way I like, and I think it has a chance to work well too. While its in the shop again, we went over the front end, and all 4 ball joints need to be replaced, along with both tie rods. Better to find out now, then on the top end on shut down.

The new tranny is in the car now, and I took it for a rip around the block, and everything seems happy. Never had a trans brake before, so that was neat to test out. I bought an MSD 3 step to work with my old 6AL, and a chip pack of 4100-4900rpm. I think that should work. I am starting with the 4100rpm chip to see how things go. If all goes well tomorrow, I should have the first passes on the car around 8. I'll keep ya posted!

I was able to make 3 passes tonight. It seems to work OK so far. I'm sure there is more in it. The air was around 4500ft I believe.

First pass off the trailer. All shocks loose. 4100rpm chip in the two step. 14 psi in the rear tires. 10.89 @ 110mph. 1.55 sixty foot. Tranny was too full and it was smoking bad on the top end as the vent was spewing out onto the exhaust. I lifted and got on the brakes.

Second pass. Proper fluid height. Up the two step up to 4500. 10.72 @ 127. 1.55 sixty.

Third pass. Tightened rear shocks to 9 clicks out of 18. Up the two step to 4900. It hit hard, spun, and did a 10.74 @ 125. 1.57 sixty.

So, as you can see, the sixty foot isn't there yet. It is hooking fairly well so far though. Tomorrow we will see better track prep and temp.

I was able to meet Jason "thedriver" tonight in the staging lanes. Nice to meet a fellow Moparts member up here! There aren't many of us around here!

Good seeing you run that super bitchin car Kenny! I'm sure tomorrow will turn out better for you! Once we get the mad wheel hop under control on the sprint 6 chicken we might be running neck and neck!!!! Lol!
I tried to get a pic of your launch but your car was too quick for my iPhone! All I got was a blur!

Haha thanks Jason. That firebird you guys are running is a sweet machine. Cool to see something a little different!

Today I will try to get some cameras rolling. I have a go pro and my regular camera.

Ended up going 10.56 @ 129 mph yesterday. There is a bit of suspension tuning to do for sure. I need to move my bottom shock mount up for starters in the rear, but I need to trim my shock mounts so they miss the wend on the diff. I'd like to add a rear sway bar to the car as well. If anyone has any suggestions, I am all ears! Here are a couple videos. I am pretty sure the drivers side rear shock is topping out on launch. The shocks I put in only had 3-7/8" of travel. I was guessing where my anti squat line is, and thought it was going to squat, but the diff is coming out of the car. When I bolted the rear shocks on, I left about 2.5-3" of room to compress, so not much left on extension. Next outing I will trim the shock mount and run more extension room.

On the upside, I made it to the final in the 10.00 class (was only 5 of us to start with) and got taken out by my friend Darryl in his 572 440-1 1970 road runner. Our cars run very close motor to motor. So, he put his nitrous tune up in and strayed it out of the hole a little to get me! haha.

Common misconception that leaf spring cars squat, rather than extend on the hit. Glad you're making some progress, and it's always good to see someone try something different!

If I just had leafs, I could see that being the case, but it's really more of a 4 link now. If I move the front of my top bar up a hole, the car will probably squat, as I am pretty sure it would put my instant center under the anti squat line, where ever it is.

I checked out the video, looks good! Your foot braking it I assume? I have not tried the foot brake yet. I competed in a local event called the 100 foot dash. Basically single runs timed over 100 feet. Here are some pictures...



Spinning a bit on this one...



Different angle of first launch... I need an anti roll bar lol
