Rear gear needed

Looking for an affordable gear set for my '95 Caprice wagon. Has a 2.56 now . Want 3.23, 3.42 or a 3.73. Doesn't need to be posi.

My buddy has a set of 3.73s that he is taking out soon. I'll send this to him...

Pete,I remember something about needing to replace the carrier whenever you change to a lower
gearset.Nick and Tim will know the specifics.

jim you are correct if you have a 256 gear you will need to get a 3 series carrier. 3 series carrier will go from 273 and up. 3 tonfun you best and cheapest bet would be to get a complete posi 323 rear out of a tbi wagon. that is what i did. then just swap them

oh you can pull axels out and hang backing plates from wheelwell and swap the rears if you dont want to bleed the brakes

Already did a cross reference on the carrier (a perk of having the GM parts catalog at my disposal). My particular carrier will accept a 3-series. Brakes don't scare me....been known to build some crazy stuff and make it work!

you'll need a ring gear spacer if you want to use your series 2 carrier.

Jason,does the ring gear spacer eliminate the need for the 3 series carrier?
Jim

Other Jason, but yes.

3ton, your book is wrong. 2.56 gears use a 2 series, 2.73 and above use 3 series. This is for an 8.5/6 ring gear corporate ten bolt.

What he said!!!

Do not overlook 3.08:1 gears they are a great set up for all around in our wagons. They are very easy to come by (including reluctor for ABS) and cheap on the Impala forum as they are the stock gear. Likely you can find a used limited slip unit as well. I had them in mine before I did the 3.73:1 and miss the fuel mileage. Better smokey burn outs with the 3.73's though. It all changes when the t56 goes in!!

if you get ring gear spacer make sure you get new ring gear bolts need to be longer because of spacer. some spacers come with the bolts. my friend made his own spacer yrs ago when he did not know you could buy one

Tim,once the 6 speed is in what will the overdrive ratio?Think the 4L60E is .70 but the 6 speed is
even better,.50 would be perfect with that 3.73 rear.
