1965 Pontiac 2+2 rear end gears

Post by 652plus2 »

I have a question about available gear sets that would fit my 1965 Pontiac 2+2. I currently have 3:42 posi and wanted to step that at to maybe 3:90. Does anyone know if there are any gears available for my rear end?

Thanks
Tony

Hi Welcome to the site...
Unfortunately we have bad news. No Aftermarket gears any steeper than 3.55 for the Pontiac 8.875 FULL SIZE car rear with bolt in 31 spline axles. 10 bolt cover 12 bolt ring gear.

NOW hope is still there. If you can find a original GM set of 3.73, 3.90, 4.10, 4.33, 4.56, 4.88, they are out there as we did have 2 sets of 4.33 sets 10 years ago found at swap meets that people did not even know what they had for sale.

So do not give up ...get on web sites like Ponitac forums and post want ads. Get to Pontiac national swap meets and you just might find them.
