I am looking for 3.55 or 3.70, 3.73 gears.
Does anyone have a good set for sale?
Thanks.
Merry Christmas all. :cheers:

No, but if you want to go with 4.11's let me know. I've got the whole rear available.

The Corvette gears are not available in 3.73 ratio. This is from the other GM rears. 3.90 is a vette gear also. You either want 3.55 3.70 or 3.90. I have some broken 4.11 gears :lol: :lol:

I have a set of 3.55 Richmond Gears that I ordered from SummitRacing (part # RMG-4900211) that I'll sell. They fit 63-79 vettes. Send me an e-mail or respond to this thread. I'll will not be back on the forum until Thursday night.

Red73,
I'm thinking of going to the 3:55......were these gears too high for you? Why did you switch to 3:73?.....your gears will not fit in my 8T1, however I'm just wondering if I should go straight to the 3:73 and by pass the 3:55 .....right now 8T1 smokes 17 wheels/tires out of hole with the 2:88 gears ET's 13.4 @ 105....figured 3:55 with drag radials should have me down into the 12's...what do you think? Happy Holidays to you and your family...Aloha Cappy :seeya

Cappy, the 3.55s are new in the box and never used. I bought them and then decided to go with the 3.73s. If I was to do it again I would go with 3.90s. You'll notice a difference switching from 2.88s to 3.55s or 3.73s. What tranny do you have in your 8T1?

how much for that whole rear w/ 4.11's?

John,

I have a complete differential unit from Mid-America with NEW 3.70 gears installed. The unit has about 1,000 miles on it. I ended up using a 3.08 unit since I installed a Richmond six speed. I would sell it outright for $600........ with NO core required........ plus shipping....

It is the '63-'79 style unit..........

Let me know...
Bob

I like my 3.90's with DR's. A good price on some 3.70's would have done the trick too!

Looking for $500 on the 4.11 rear. The previous owner installed a 3.08 for better gas mileage, but gave me the 4.11. He might have given me a receipt showing it was rebuilt at some point, I'll look for it. Email me at barry.firebaugh@digex.com if you're interested.

Rod,
I bought a TH400 beefed up to the max with the 2:75 first gear in it....however after looking at what it would take to install....I nix the idea and decided to go for the rear end since it was a drop in job, verses the trans change out, which would have presented major mods to install. Now I'm stuck with a TH400. I don't want to go too low with the rear gears since wheels are smoking out of the hole already. But I sure would like to have the extra umph maybe 3:55 would give from a stop light without rev'ing the engine to 2000 rpm launch speed at the drag strip........Aloha Cappy :seeya

Hey Fireball,

I sent you an email a couple of days ago about that 4.11 rear. I want it if you still have it for sale. Email me.
