CA 3.07 posi gear set - The 1947 - Present Chevrolet & GMC Truck Message Board Network

KrazyRay · 08-02-2012, 12:23 PM

SOLD!!! I have a posi gear set from a 70 1/2 ton truck. Everything looks great except the ring gear has rust on one side from water condensation from sitting in one place for years. I recommend changing out the ring rear. $150 plus shipping. DesertCat is first up.
Thanks,
Ray

I'll get in line after DesertCat. This is the ring and pinion and posi case removed from the housing and shipped? Shipping to 30127? I would want all the sims and spacers with the carriers bearing sides marked for easy install. Thanks, Dan

I GUESS I DIDN'T TYPE FAST ENOUGH!!!!

From what I understand, this is a 3 series unit and Richmond makes gears up to the 4.56 that will fit this. But for stock gearsets you would want a 4 series unit for 3.73 and numerically higher. I am no expert on this... that is just the info I have read about it. YMMV...

That is my understanding as well. Aftermarket gearsets from 3.73 up that fit on the 3-series are made special and won't fit onto factory 4-series carriers. I believe the ring gears are thicker. You can also get spacers to enable using oem style 4-series rings on 3-series carriers.

How do you identify the 3 and 4 series?...... 3.73 is a4 series oem
