I am on the hunt for a 3.45 gear set for the BOrg Warner 9 Bolt gear set. I bougth the motive 3.70 gear set and had several problems settign it up, and trying to get a good contact pattern. When I got it set up right it howled like a dog. So I said the hell with it, so if any one has a 3.45 gear set for a borg warner. Let me know the prices shipped to 48623. Thank you

I have a complete 9 bolt rear end with factory 3.70 gears and a posi. looking to get $300 or shoot me an offer and we can deal.

What year did it come out of? Is it a true Borg warner? I didnt think they came with a factory 3.70 gear set? I thougth just 2.77, 3.27? and 3.45? What is the lowest you would take for it?

pm sent!

They did make a factory 3.70. I had one before. If I recall it was an '85 rear end.

I also had a 85ta that had a 3.70 geared 9bolt and it didnt hum. was strange gears though.
Good luck. Hope ya can figure it out or get a set of stock 3.70's
I have a 3.45 9bolt in my car now and would love 3.70's again but Im not at the point where I want to tear it apart right now to swap. or I would.

Hello,
I have a some of those if interested give me a call 716-445-0259 Dave

The Borg Warner 9 Bolt I have came out of an 87 GTA. It is a factory 3.70 gearset and it also has disc brakes. I would like to get $300 for it. Otherwise I am gonna keep it as a spare for my racecar.

What do you have to offer me Dave? You have the whole rear end or just the ring and pinion?

good price. Thats around what I sold mine for and the guy had it picked up and delivered to Indy.
