this seams wierd, 83 s-10 with 2.8 and 5 speed 4x4... bone stock with 4.11?

[55Willy]

the gears were marked 9:37 which would be 4.11 right?

and the stamps didn't the pattern I have seen on others with the GM and the 7 or 8 digit code and then the pinion and ring gear stamp and the date code. this just had the GM and i think it was 8 digits and then the 9:37 on the end of it.

9/37 = 4.11 that's for sure. Just to make sure count the teeth and do the math.

Scott would know better than I about motors and their power bands, but my Amigo, for instance, has a similar (3.2L) V6 and 4.10:1 gears stock... something about smaller motors needing more gearing, or maybe it depends on the torque curve?

I pulled factory 4.11's and a gov' locker from an early model S-10 that had a 2.5 4 banger in it. Buddy used the body and frame to put on top of a K5 chasis, welded frame to frame and used on the road, very scary I know but we were much younger then. I snagged both the front and rear axles and put them under my long bed with a 4.3 and only 30" tires. With a shift kit that was a very very fun truck.

Yep, 3.42's and 4.10's used to be the most common S10 ratio's out there. I had to search hard to find some 3.42's (kept finding 4.10's) for my friends S10 a few years back. I can't recall anymore, but the combination was something like small engine, manual trans=4.10's. Larger engine, auto trans, 3.42. His was a 4.3/700 combo.

Small motors tend to get deeper gears. Same deal with the 2.5L Wranglers; most had 4.10s.

I'm looking for a set of 4.10s for the front of an S-10, and from what I've been reading 83 and 84 were the only years for them. When the 4.3 came out pretty much everything got 3.42s, and 3.08s for 2wd's.

 

[55Willy]

4.3 didn't come out til the 87-88 year. so there should be more out there.

My 86 trooper has 4:55's stock. 4:77's were an option on some models.

there is a difference in the code for the gears between 410 and 411 the 411 specificaly was shown under the H** code410 were a g** code. learned that from 1987 s10 I owned for 2 years. my truck was also a 2.8l 5 speed 4x4 with all the skid plates and off road shocks. also has 235/75 15 tires not the 215/75 15 tires.

typicaly the 411 was used in the more off road ready trucks.

wonder if you have my old truck?
