I just read this info in the Tech Archives... http://www.moparts.org/Tech/Archive/axle/22.html It looks like 3.91 may be the limit for a 8.75 sure grip. 8.25 had a 2.76 sure grip though...

In a 489 or 742 case (big pinion). I had to sell my last sure grip with my Charger and now need one for the Challenger. I have a 2.76 open (489) for now, but i need the sure grip. I have never seen a 2.76 sure grip in this case/pinion size, only 741.
Did they not make them or did they just all get gear-swapped for better gears..???
Also, were there ever any aftermarket gear sets with higher gears for the 8 3/4"...??? I mean 2.5's or ???
I pulled a 2.76 sure grip from a 66 c body and it was a 742 case

Doc, I like you and all, but you are in the minority on this one. You are the only one that I have ever heard refer to gears this way.
Short, low, digger, deep gears = 3.91 and numerically higher.
Tall, long, highway, freeway gears = 2.76, 2.93 etc.

NO ...all it-is is just a way something is described. YOU want to call a gear (that is short numerically) TALL .... fine with me.

OK ...let me make it EZ for you ..... Here we have TWO #'s ..... 222 and 444. WHICH # is more numerically bigger, larger .... aka taller ? Now if you want to "corrupt" that reasoning to mean the opposite .... lite-up another I know what you are trying to say ... I have been dealing with this MORE TIMES than just here .... BUT THIS is just like what they do to us in the voting-booth sometimes ... they have us voting YES on a ballot ... if we don't want it to pass.  ...

Rear axles are named the same way as transmissions. In transmissions, the "Low" gears are the higher numbers 3.09, 2.66, 2.74, 2.45, etc. "High" gears are the lower #'s, as in 1.0, .70, .67, etc.
Same thing for the rear axles - low or short gears are 5.13, 4.56, 4.30, 4.11, etc.
High or tall is 2.45, 2.71, 2.76, 2.94, etc.

Not to throw a wrench into things, but I've always thought and heard that the difference was in relation to the engine RPMS at a certain speed.... hence a "low" geared 2.76 is only turning a low RPM of say, 2800.. where a "higher", steeper geared 4.11 is in the upper, higher RPM range near the redline...
High geared cars climb the tach faster, low geared cars climb the tach slower... But.. a TALL geared car has the 2.76 because it runs out faster like running with longer legs... mad max-style. A Short geared car runs out of steam quickly, like running with short legs.. 1/8th mile warrior.
so there is an opposite in the terminology... Low and tall and high and short...
But "High Gear" in relation to *gears* like first through fourth comes from old two-speed transmissions, in relation to the speed. Rabbit and Turtle...

First i've heard ov this...??? I've read stacks... hundreds and hundreds ov Mopar mags and browsed years ov Moparts, never heard ov that. Anyone else confirm...??? I suppose it'd be easier to find a cheap 426 Hemi than one ov these gearsets though...
As for the rest ov this thread... Here i am thinking 'wow... three pages ov info...' Nope, just that stupid argument again. Rest it.
I guess they exist... the big case 2.76 sure grips... I'd sure like to find one. I was gonna stuff some 2.76 gears into my 3.23 489 case if it came down to it, but that car sold.

Not one of you guys explained the "gear" thing correct !!! My take on it but Ratio is comparing one number to another . So if you have 4.11 gears .....they are low gears but high ratio (relatively speaking) If you have 2.76s , you have high gears and low ratio. Why???? Because when you say you have 4.11 gears it means 4;11 to 1 or for every time your axle turns once your drive shaft turns 4:11 times........ If you have 2:76s .... axle turns once and drive shaft turns 2:76 times Conclusion : Low gears = high ratio High gears = low ratio

The ratio thing just confuses people. All you need to know;

Ahhh DP .... now WE should take your word on this ? ... and on your second post ADMITTING confusion ..... and you being from B C ?

I  to DD's terminology .... a 2.76 gear is a HIGH SPEED gear.

Maybe slightly interesting, how many note that only odd tooth counts are used on gears and why?
Not always odd count for both:
3:23
42 teeth ring
13 teeth pinion
4:57
32 teeth ring
7 teeth pinion
4:86
34 teeth ring
7 teeth pinion
As was explained to me once by an engineer:
The reason for having ratios that are in the decimals is that with each revolution a single tooth on the pinion will not contact the same tooth on the ring with every revolution.
The pinion tooth advances one tooth per revolution so that it will contact each tooth on the ring gear through numerous revolutions.
Hope I explained that correctly.
Frank
Find another engineer.
There are repeating and non repeating patterns, not to mention the one tooth theory is wrong. I'm going to use Ford 9" ratios, since they are the most common.
A 3.00 is a common pickup gear and has a 13/39 tooth count. Each pinion tooth hits the same 3 teeth on the ring and is a repeating pattern. A 3.50 ratio has 10/35 and each pinion tooth hits the same 7 teeth during 2 rev's and is (semi) repeating.
As to the "one tooth" theory. A 3.08 ratio has 13/40 teeth and each pinion tooth is one tooth off, so after 3 pinion rev's it has went 39 teeth and is one tooth off the 40th tooth. A 3.23 ratio is 13/42 - again, after 3 rev's has went 39 teeth, but it is 3 teeth away. A 3.55 has 11/39 so 3 turns, 33 teeth, 6 off. Follow?

A high gear is for high speed plain and simple and a low gear is for low speed. Doc needs to lay off the crack pipe. I supose you start your transmission out in high gear and work your way to low gear when your really goin fast

... you s ... lay off the .... The transmission inner gearing is way diff than the final drive rear-end ratio. PLUS the resident Xpert here (Doc Diff) labels this whole deal as a 2.76 being a low-ratio BUT IS a high-speed gear. I will accept that ... but you just keep "hitting the pipe". Well you can HITit by yurrself.

Hah! I guess that means you dont have me on that list then. Can you 'ignore' the original posters ov threads? That might get confusing. I dont use that feature, so i dont know how it works.
So yes, i guess i am looking for a 489 or 742 2.76 geared sure grip pig. That 68 Charger in Hotrod years back went 190mph on that pig with a '505HP' 440, so i guess it'll work for what i need. I'd still prefer something higher (numerically lower, for the topically-challenged), but i'm sure the 2.76's will bad hard enough on clutches as it is.
I now return you to your bickering. And for when this finally gets resolved i will say this: long rods make more power....

It's the difference between "drive" and "driven" regardless of the mode of power.......the pinion gear ring is the "driven" gear not the "drive" gear......hence the term "overdrive" (over, above, taller, higher.....)
MikeR
Everything from the flexplate or flywheel back is "driven"
However , we don't use the term in its correct meaning .
we could say the tranny is driven by the crankshaft
the "driveshaft is driven by the tranny
the diff is driven by the driveshaft but it would just complicate things more for the newer crowd that is just learning the mechanics of our automobiles.

Anyone know the ratios they used in super speedway Mopar NASCAR's back in the day? 
Teams had racks of 8 3/4 center sections with different gears ready to go. There were many choices. In the area of 2.76 or 2.94 for Daytona and Talladega. We just switched my car from 3.23 to a 4.75 to make it easier to move around at low speeds because the tire diameter is so large. The 4.75 gear set installed was used in a different car on mile dirt like Springfield and DuQuoin.

Haven't you guys learned to not argue with the Doc? he's not always right, but he'll never admit he was wrong. yes, we all know that EVERYONE EXCEPT the doc, calls a 2.76 gear a "tall gear" and a 3.91 gear a "short gear"
he'll refuse to admit that, and will argue to the death that he's right.
Often times, it's best to let his comments go and ignore them.
I'm actually kind of surprised he hasn't told us about how perfect his car is and will run 12s and get 20 MPG with a 2.76 rear gear and a t-quad, and that the rest of us are all doing something wrong because we can't duplicate what he's doing.

I am "WRONG" ? .... for calling a gear-ratio that is low numerically a "short gear" ? No ...I will not admit that I am "wrong". But I am BIG ENOUGH to admit I uNderstand the reasoning behind the opposite point-of-view or opinion. But then others here can not offer me the same consideration...
You allege that I have never admitted when I was wrong? ... there have been several instances over-the-years where I have mis-spoke or didn't have my facts right OR had all my ducks in-a-row ...and have admitted same.
And as far as my car ? ... so I like an odd-ball combos. WHO else here specifically sets-out to put-together a SHORT GEAR combo that runs half-way decent. And as far as someone DUPLICATING these efforts? ... I would hope that if anyone here tried ... that they could do-it with no-effort. The motor that was in the car then was a blow-by special.
And Tom ...I never claimed 20 mpg. I said that I would like to eventually put-together a combo that would run 11.99 and get 20 mpg.
Now will you admit when YOU are wrong?

I think you're the only one who understands the "reverse logic" on how a low number ratio is "short" I understand what you're saying, high, low, tall, short, big, small...2 is less than 3, therefore 2 is shorter than 3. therefore a 2.x gear ratio is shorter than a 3.x gear ratio. but...you're the only one who sees it that way and you're right, I made up the 20mpg claim, because I couldn't remember what you were actually getting, but I remember that it was high teens with a carb that nobody likes and a TALL gear ratio in the 2.x range. as for your odd and different combo...nothing wrong there. I think that's why most of us like Mopars....they're different and not boring. (that's why I'm here. At the Academy, Camaros were everywhere, classics and late model. same with Mustangs, same with Corvettes. they were boring. if I got one of those, I would be "just another lemming following the crowd" no thanks! )

i pulled an 8 3/4 2.76 sure grip out of a 69 sport satellite back in the day. i am not sure if i am correct, but i always expected that the higher (or taller...hee, hee) geared stock third member would likely produce a less strained or "abused" sure grip carrier...and the carrier might be a better candidate to throw in a rebuilder third member without actually rebuilding the carrier.
Did I hear Bigger ? ... aka TALLER ? ... ...

While I should not feed the troll, DocF, I do not think it means what you say it means.... here's DocDiff's reply: Quote:
2.76 ratio: "high" speed gear
4.88 ratio: "low" speed gear
Transmission: "low gear" first gear
Transmission: "high gear" overdrive
Transfer case: "low range, compound low" low speed
Transfer case: "high range" high speed
where in here does he call a 2.76 a "short gear" and a 4.xx a "tall gear"?
tall/high gears = NUMERICALLY smaller
short/low gears = NUMERICALLY bigger
what's confusing you is the proper way to think of it is the inverse of the stated ratio, as the important way to look at it is "X" input creates "Y" output
a 2.76 gear means 2.76 turns of the driveshaft turns the wheel once. a 4.88 gear means 4.88 turns of the driveshaft turns the tire once, so to compare, you need to normalize the input.
with 4.88's 1 turn of the driveshaft turns the tire .205 times
with 2.76's 1 turn of the driveshaft turns the tire .362 times
.362 > .205, and therefore the 2.76 (SMALLER NUMERICALLY) is "taller" or "higher"
in 15 years as a degreed mechanical engineer, you are the ONLY person I've ever heard consider a 2.76:1 gear as a "low" or "short" gear, and a 4.10 as a "high" or "tall" gear.
