Found a Stude Lark with the "TT inside the double circles" emblem on the rear of the car.
I'm on the understanding it means "Twin Traction".
Is this rare in a Lark or why was this put on the back?
I'm assuming it has to do with the rearend.
Can anyone enlighten me on this one?
Would this make the car worth more? A real keeper?

You are correct.
The (T(T) denotes "Twin Traction" limited-slip differential. Pretty common option and very desirable.

Do you mean very desirable back in the day, or desirable now in that it makes it more sought after?

You want to check that the car really has Twin Traction. The emblems used to be very inexpensive and some people would put everything on their cars even if it did not apply. I have seen non Twin Traction cars with the emblems.

Much more commonly than that, they were replaced with a Standard Unit to conserve $ ! [:0]

Just turn a wheel by hand while the axle is raised on jackstands with Trans. in Neutral, while adjusting the brakes etc. you will see the other wheel turn the same way if it has TT.

In a '63 Lark, it could add a slight bit of value if it is a JT powered Lark, if not about 0.
Could also mean it's from the RUST belt!

Also, if it hasn't been lost, there should be a metal tag affixed to one of the rear end cover bolts that identifies a limited-slip diff. Easy to check!

Excuse my ignorance but what is a JT powered Lark?
And what if it's in a 62?

What will the tag have stamped on it?
My 57 transtar has a tag on it but I doubt if mine is Twin Traction.

Are you telling me that you have been here since 11/2006 with over 200 posts and you never saw all the Talk every week or two about the Jet Thrust and Super Jet Thrust '63 and '64 high performance Studebakers that Andy Granatelli and the Paxton Products Div. of Studebaker Corp. racing team drove to scorch the Bonneville Salt Flats and set over 200 World Speed records with?

Studebaker went on to release these as available to the public in I believe, April 1963. Later for the 1964 yr. models the R1, R2, R3 and R4 Avanti Engines became available on all models.

The JT powered, Super Lark and Super Hawks for sale on ebay are constantly talked about here, especially when JDP (Goldenhawk) has one up on ebay.

With most of us ordinary Studebaker folks usually referring to them as R-1, R-2 and the like maybe he just had a slight lapse. No big deal.

The rear axles should have a tag on them with the ratio numbers - TT or not. If it's a TT, there's a fair chance than it has a second tag that has "45", "45A" or "45B" on it. This would indicate that it has the TT clutches inside.
Another way is to remove the fill plug and stick your finger straight in the hole. If your finger hits something that's only a half inch or so inside the hole - that's the TT clutch case. If you have to stick your finger in any further to feel something, it's not a TT.

57 pickups COULD be so equipped. Mine was.

Again, pardon my ignorance on Studebakers!
My life doesn't revolve around Studebakers and I don't read any/every post that is on here.
Sorry if my ineptness has offended your expertise on the subject.
I will try and refrain from asking such frivolous questions in the future.

Nitram, here's a pic of my Lark's rear end. It's a little greasy, but if you look hard you can see 3 tags:

1) that reads "45C".
2) that reads "43-13 / 3.31" (the axle ratio), and
3) that reads "Twin Traction Axle Service And Lubricate Accordingly"

http://i132.photobucket.com/albums/q26/clarknovak/From%20the%20start/DSCN0478.jpg

You should have these tags if it really is a TT axle (again, assuming they've not been lost along the way). If you don't have any tags, turning a tire while the car is in the air like Rich outlined will tell for sure.

BTW, don't be offended. No one was trying to put you down. Forum postings don't read they way they would sound when accompanied by a friendly smile :)

Nitram .... Don't let some of the remarks get to you, these web links should be helpful to explain the JT "Jet Thrust" or R series engines developed primarily for the Avanti but also available in what most refer to as Super Larks and Super Hawks.
