Ring & Pinion Gear questions???

[David.C]

Which ring & pinion gear is correct for my 1980 El Camino? I keep seeing “3.23 Ratio & Numerically Higher Carriers” or “3.08 Ratio and Numerically-Lower Carriers”, which one is correct for my car? And what are they talking about when they refer to carrier 2 or 3? See links below

Most likely you need the set for a 2 series carrier. Most of our cars had 3.08 or taller gears in them from the factory. What is the ratio in your car now?

I don't know, what's the easy way to check? I'm guessing pull the diff cover and count teeth?

quick way to check the ratio is to raise the rear off the floor, put the trans in neutral, and spin the tire one revolution. then count the amount of times the driveshaft turns. You might want to use a white marking pen on the shaft and use the valve stem on the tire for reference. Or, if you have the RPO code from the sticker, thats easiest.

It,s stamped in the end of the pinion and around the edge of the ring gear,divide the big number by the smaller one.This set has 15 and 41 works out to 2.73 ratio. everything below 3.08 would be a Series 2 carrier and Every thing above is series 3.

The answer is I have the standard 2.41 rear end, 2 series carrier it is. thanks all.
