Aspen and Volare Gears

[1980 R/T]

Opened up the rear-end on my new 1980 R/T and noticed that its a sure-grip. I couldnt read the gear ratio so does anyone know what gear sets they used in Aspens and Volares?

should be a 2.76,or 2.21 if its an automatic. if its a manual 3.23.i could be wrong. this should get you realativly close! Trans in neutral, One tire blocked, one tire rotated through two full turns while you count quarter-turns of the driveshaft by noting how many U-joint caps come to face the pavement.

Divide that count by four and that gets you within very close range of the rear axle ratio.

I thought some of our cars got 3.55's. Could of been a rarely choosen option, but I could be wrong. I know a majority of the cars were 2.76's.

the ratio is stamped in the ring gear

Thanks for the feedback guys. I will have to try that out 1980volare thanks. Hopefully its around 3.23.
The ratio is stamped so close to the teeth on the ring gear that its unreadable :(

I have an 8-1/4 here for mine that had a set of 2.71s in it, that I have a brand new Sure Grip siting here for, along with a set of 3.55s and a full Randys Ring&Pinion Master Install kit. Housing all blasted and multiple coats of POR 15 on it! (car had a 2.76, 7-1/4 weakling in it when I got it)

I found the build sheet under the carpet so I was able to confirm that everything was indeed original.
The options as far as gear ratios go are:
2.24/2.26
2.45/2.47
2.71/2.76
2.94
3.21/3.23
3.55

The gears in my R/T are 2.24/2.26 :rofl:

Bummer. I suppose that was typical for a second gas-crunch era car, though.

You can always count the number of ring gear and pinion gear teeth and get the ratio that way.

Well atleast ill be getting decent gas mileage, thats the one and only perk to those gears.
