E-body: What years & engine combo had rear Sway Bar

E-body: What years & engine combo had rear Anti-Sway Bar? Also, what is the going price for a used original one? Thanks.

My '74 European export model had one. I think they were supplied to the EU with all the H/D suspension upgrades. It was taken off years ago, we have a drag race torsion type fitted now.
Edit: It was a Rallye spec with 318.

My 73 340 Ralley has one.

I have a bar off a 71 'Cuda 340. It was an automatic.

It is my understanding that it was on the Challenger R/T, T/A and Rallye optioned cars EXCEPT the very early 70 R/T's didn't get them automatically.
The Cuda & AAR got them but I am not sure if they were on the very early 70 Cuda's.

There was probably other options that I don't know off the bat but somebody will come along and correct me if I am wrong..

I believe there was a 340 Barracuda that technically wasn't a Cuda but trimmed out the same as a Cuda. Correct me if I am wrong.

As for cost they were pretty common. The last time I bought one it was less than $100 for the whole setup but that was over 10 years ago.

In 1972, 1973 and 1974 the Barracuda and Challengers were eligible to be equipped with a, handing and apreance package, it was the Cuda and Ralley Challenger.
You had a choice in engine Cuda and Ralley Challenger. Either could have been ordered as 318 or 340.
In 1974 318 and 360
They had the frint and rear sway bars, as part of the package

my buddy's 73 rallye challenger is a 340/4 speed, and it is equipped with a rear bar.

While we're on the topic, it was my understanding that dana 60 cars did not receive the rear sway bar because it would not clear the dana? Any truth to this?

Yep - truth. NO Dana cars got the rear bars. SUPPOSEDLY, all 1970 340 & 383 Cudas got the F&R bars. T/A's & AAR's all should have been equipped with them. *My first car that I bought in July 1976 was a 1970 340 Cuda that I bought from the original owner - he ordered it & it was an early production car - it DID NOT have the rear sway bar. I bought a new one from my local dealer but never installed it, so it is on my AAR now. (my AAR had been drag raced from around 1977-1982 when it was finally parked & has not been on the road since - the rear bar was missing). Also I have an old article from 1969 in one of the car mags about the new Cudas, & in the article it specifically mentioned the Cudas that got rear sway bars - 340's & 383's. The article claimed that Chrysler engineers "did not equip big block E-Bodies with the rear bars because in hard cornering, they would skitter off the track tail first" if equipped with them. So peculiarly enough, we saw NO 1971 Roadrunners, GTX's, or performance Chargers with the rear bars, but saw ALL these performance models in 1972-4 get them.

So, big question for the 1972 440 4-speed GTX's & Charger Rallyes - did the Dana cars in 1972 have the rear sway bars?

it would be easier to answer if you were more specific ....

for 1970 E-bodies, the rear sway bar did NOT exist until Trans Am/AAR production
prior to that S13 was front sway bar ONLY (STANDARD on BS-JS cars) & after A53, S13 included front and rear sway bars (the question might be: on what date did S13 ADD the rear sway bar to its contents list?)

ALL 440HP, 440+6, HEMI E-bodies had S15 included as part of the engine upgrade - front sway bar ONLY was part of S15 (ALL DANA60 cars have S15)

some suspension/brake tweaks must've been learned via the "TRANS AM" program. during the '71 model year the staggered springs went away on some/all of the axle package cars & 11' rear drums appeared on disc brake cars-
& the '72 440 cars do NOT have staggered rear leaf springs & the DANA60 cars do have a rear sway bar

Here's the rear sway bar on my old '73 Charger Rallye 340 - a straight & pretty thick bar. The Dana car in the photo has a different design bar.

Found some more photos: (looks like the Dana cars had a different bar for sure)

For my own brain clarity, was there an S15 and S13 as listed above or was that a typo?

If there was an S13 & S15 was the S13 front only and S15 both or ???

1970 - ALL BS & JS cars have a front sway bay

S13 = rallye suspension (STANDARD with BS & JS) rear sway bar after T/A AAR production
S15 = extra HD suspension (included with 440s & HEMI) OPTIONAL on 340 & 383 cars - NO rear sway bar

Awesome thank you for that info.

Both of my E bodies have the rear sway bar. One is a 1970 Barracuda Gran Coupe that originally had a 318-2BBL and the other one is a 1970 A66 Challenger convertible. I know the history of the Challenger since it was bought new and it is untouched since 1984, The sway bar looks very original. According to the fender tag it appears the A66 Challengers got the rear sway bar. Part of the package was "Rallye suspension." The sway bar looks very original on the Barracuda too but unfortunately I just decoded the fender tag and it doesn't say anything about it coming from the factory with a rear sway bar. I think the rear sway bar really helps these car drive and handle a lot better. I like my cars to be mostly original but no way I am taking off the rear sway bar.

My former A66 Challenger did NOT have a rear sway bar. And was a completely unrestored untouched car when I bought it early/mid 90s time frame.

But I added one to it.

I bet they were both built after A53 production - what are their SPDs?

S13 was an orderable OPTION on a 318 car & was required with F70-14 tires on a 318 car

Im pretty sure the only cars with a Dana that were avail with rear bars were 71-72 B bodies ( I've seen a couple, and it's a completely different style bar and mounting compared to an E body )

I've never seen a 71 B-Body with a rear bar, so I'm going to state that the '72's were the only Dana cars that ever got a rear sway bar. And correct me if I'm wrong, but I don't think there were any 4-speed 440 cars built in '73-4. How about a '73 Charger Rallye or GTX Roadrunner with a 400 Magnum & 4-speed? Was it available? If so, did it get an 8-3/4 rear?

The Barracuda was an early car scheduled to be built October 15th, 1969 and the Challenger was a late car that was scheduled to be built on June 1st, 1970. Neither car has the S13 code on the fender tag. I decoded both cars on ebodies.org. They have a webpage where you put in what the fender tag or broadcast sheet says and it decodes everything for you. You can find that here:

Forgive my ignorance but what is A53 production?

My 1970 340 Cuda, Automatic, has a factory rear sway bar.

The only 71 B with a rear sway bar that I've seen is this 71 Satellite LAPD N code car.
72 was the first year for passenger car B body rear sway bar and yes the 72 B body Dana is the only Dana with a sway bar. as far as I know. The Dana sway and the 71 8.75 has a dip in the center and the 72 8.75 bar that I have is straight across the center. .
We've had 3 Dana E bodies and none had a rear sway bar.
Also as you can see the E and B bodies rear sway bar setups are totally different.

A53 = "TRANS AM" package & S13 would not be coded on a fender tag
the rear sway bar did not exist in October 1969 - it was added to the Barracuda after the factory build

Thanks for the information 6bblgt. Dang! After seeing BigDaddys440 fender tag I was hoping the rear sway bar was original. Oh well, I am still keeping it though. Whoever put it on used all factory parts.

Just curious but why isn't the S13 code on the fender tag for my A66 Challenger? Was it included with the "Rallye Suspension" package?

I have a 70 model A66 Challenger that I have owned since 1979. It has a factory rear bar. The VIN on the car places it in the middle of T/A-AAR production according to info from Alaskan T/A.

Friend just bought a survivor-ish 1970 N-Code 'Cuda. Los Angeles built car.

No rear sway bar ever.

No holes for frame brackets, U-bolts never apart that sandwiches the sway bar plate that's not there

SPD of 106 (Jan 6, 1970)
