E body torque boxes

When was torque boxes installed on E bodies. Was it hemi only cars?

I believe convertibles and the TA's and AAR's also got them, at least mine did. Not sure about others than the above. Possibly Cars with Trac pac options???

(Now...THERE'S a slippery slope...)

Converts had them.

Torque boxes are probably the product of axle packages, motors, body type and what the line worker felt like doing that day.

Tell us what type of car you have and maybe we can tell you if it likely had torque boxes.

We have a 71 440-6 4-sdp that has them and a 71 440-6 auto that has fronts but not rears.

my u code has them and a skid plate!!

You need to supply more info to help solve the puzzle. Is this for and E body or a B body?

What gear ratios does each car have?

Don't forget a66....

A66 had these torque boxes?

70 440 sixpack, auto, with 4.10 dana, E body
have front and rear.

I have the same options as 72ls5fla and also have front and rear torque boxes. I believe all 70 E-body 440 and Hemi cars received torque boxes, regardless of axle package. I can't speak to 71, however.

My 70 Challenger 440/auto with Dana has them. October 69 build date.

E-body. Thought that was what this thread was about.
4-spd car has 4.10 Dana
Auto car has 3.55 8.75.

My A66 does not have them.

My A66 does not have them.

Let's see some pictures,some with and some without

Here is my old 70 a66 4spd 3:55 gear. 9/28 spd. Pictures not great but what I found.

Both those will have torque boxes front and rear

I have a 70 A66 Challenger 340 convertible.
It has both front and rear torque boxes.
I believe that ebody convertibles all got the boxes

My A66 Challenger 340 convertible has them on both front and rear.

70 six pak challenger.

my lowly 318 71 barracuda has both built june 14 had 7.25 rear axle

Most 71s have the fronts. Having the rears would be odd for that application unless it was a convertible

I agree with Morty426 - I've never seen the rears on a 70 or 71 with that engine application.

My 71 383 4 speed, A31 axle package has front, my 70 440 auto 355 8 3/4 has front and rear, and my 70 340 auto air has front and rear, also has rear sway bar (torque boxes seem original, rear sway cant tell, LA built no broadcast sheet). I had a 71 GC 318 auto air no torque boxes.

forgot to mention my 71 318 7 1/4 is a convertible

they are technically frame connectors.
they connect the front and rear framerails through the rocker panel, which btw convertibles had heavy 1/4" angle iron spot welded to the inside of the rocker panels for rigidity.

i had a 1970 318 i forgot if it were 3 or 4-speed on the floor, but it had front and rear tork boxes, i would assume a factory mistake.
