I've wondered the exact same thing.

The right rear actually rises up into the body from the pinion trying to climb the ring gear. This causes the springs to wrap up(especially on the right) and that is why there are more leafs on the right. Also they are shifted forward. Our friend gravity causes the body to drop down on the back right when the diff. tries to rise.

EDIT...just noticed..right side sits lower?..In rear?

Yeah...the right rear (passenger) side sits lower on my car with the SS springs installed. Is this right?

No this is not right. You might check for a broken spring. Should set higher on the right rear. Spring on right rear should have more leaves and the short leaves on the right rear spring should be shifted toward the front of the spring.

The torsion bars are adjusted evenly up front as measured by the upper pivot in the LCA. The length of the thread/bolt head exposed on the adjusting bolt for the torsion bars is about 1 7/8" on both sides.

The springs I have now are 4 years old although I don't run the car much. I seem to think the car always sat lower on the right side with these springs though but I am not 100% sure of this.

If the car really should be sitting higher on the right side do I need to be thinking about new springs? Tri-city...dvorak...caltracs?

Here is a pic of how the car sits.

I would crank up the rightside (passenger) torsion bar and see if the car levels out. My car sat that same way last w/e. No problem with the hook, I did crank up the rightside torsion bar to level it later in the day.The other thing you might try is to add 100lbs of ballast to the trunk and see if the car will hook. Pinion angle is not going to help it hook, more to help the U joints live when the rearend rolls up under power.

if didnt know better say leaf where switch

or wrong springs on car to start

When I was playing around with the torsion bars the other night the rear got a little better (1" lower on right side) but I had the passenger side t-bar cranked up pretty far and the drivers side was all but unloaded.

I checked the part#'s on the springs before I put them back in and they are correct for a 3600lb. E-body. There are 5-leafs on the drivers side and 6-leafs on the passenger side. To me it seems like everything is set up right?

A call to Dvorak would be entertaining if nothing else. I like that guy, he tells it like it is and he don't mind helping people.

ok i'll be more serious now
torsion bars are most likley the issue
you shouldnt have to crank these out of site
i make mine same both sides normal ride height as came from factory
understanding that the motor does sit to one side of car,, pass side,,
but i still make my ride height the same both side of front,, + or - 1/2 " for my desire?
then fix the rear of the car
but on ss springs i always go heavy ,,
if the car is 3400 # i'll run 3800# springs
same on 3200# cars
m o only

I called Dvorak and he was short on time but told me to pull the leaf springs and turn them upside down. The right side spring should at least 1" taller than the left. If it is not then I have bad springs. He also told me to find a local spring shop that could build a set of springs if I give them a blueprint. That is about all I got for today. I am supposed to call him back tomorrow.

I pulled the springs and at the perch/mount the right side is about 1/2" taller only because of the (2) extra short leafs on that side. Moving down the back of the arc the largest difference is +3/4" taller on the right side spring. He didn't tell me where to measure but at no point is the right side spring +1" taller compared to the left.

Here is a pic with the left spring in front of the right.

This is a little closer shot. Not sure if you can really tell anything from them or not?

I can tell ya springs aint your problem.

Looking at your video again, it appears the front end just doesn't jump up high enough to overcome the rear, then right after launch it drops back down, thats your problem, plus the car sits too high in the rear, if it were me, i'd try & level it off & get the front to jump up easy & be higher then the rear at launch.

While I probably could get away with using the existing springs it just bugs the crap out of me that my car sits so low on the right side (which is also the wrong side). If I am looking at making changes to things I figure I mine as well start with a set of leaf springs that are right....right?

I have been back and forth with Dan Dvorak a couple more times. The peak of the arc on my springs is at about 10 1/4" on the left and 10 3/4" on the right. He said that is way to high and it should be around 7". He said that alone would cause the rear to sit too high and not allow the front end to lift enough to overcome the center of gravity? The rear shackles are both pointing back at the correct angle so he doesn't know what Mopar did when they made them? He said we could take some arc out of them but then the rear shackles would be pointing back way to far so the springs would most likely need to be shortened. It sounds like a lot of trial and error and work to try to get them right.

So at this point it is going to take some modifications to the springs that are on the car or just go with the Caltracs set-up and be done with it. Dvorak actually commented that he used to build springs but got out of it because everybody was switching to Caltracs.

dont throw the old ones out..
they sound like B body station wagon springs..
to the right person they may be useable.
