Will this fit a 85 Buick Regal with a 2.73 posi?

Thank you for your question. The Summit Racing SUM-741011 ring and pinion will fit your GM 7.5 in rear differential if you have a 3.23 and numerically higher carrier.

Q:

it says it works on 3.23 and numerically higher carriers- how do I know what carrier I have? I believe that my current ring and pinion is at 2.73 but it could be the 3.23. Is it still compatible?

Asked by MABEL on July 04, 2017

A:

These gears will not work on a carrior 3.23 and below ...needs to be a 3.23 or higher gear to work....unless u use a ring gear spacer...i wouldnt do that ....ive always bought a new carrier with a posi...no questions asked..

Good quality ring and pinion set

Summit RacingSummit Racing Verified Purchase

SUM-741011
Appears to be good quality ring and pinion. Instructions were bit short for my kind a beginner but with help from others they do the job. Haven't yet driven them so don't know more about quality than what they look.

Good gear, had 4.10 which was fun but the 3.73 gave me alittle bit gear for daily driving. Great for an M6.

Good, but noisey.

Summit RacingSummit Racing Verified Purchase

SUM-741011
Replaced factory ring and pinion in my '98 Trans Am with the Summit 3.73 ring and pinion. I have taken the car down the 1/4 mile several times and the gears held up fine. My only complaint is over about 45 mph on the highway they do tend to make a "howl" type noise.
