Check out my rear end

[89Suburban]

I always thought that every truck in the 80's got either a Gov Loc or an open diff, but @89Suburban had a rig with a factory installed limited slip.

With Andy's info, then in 1980 GM did still have their posi units in some trucks.


The RPO code, would that be different than G80?

Hey Paw Paw, @89Suburban any info you can share on your Suburban?

I don't recall about the RPO code, but I do know that the G80 cade was also used in 80's cars that had a limited slip.

PawPaw's Burbs were '89 and '90, but I don't remember which one had the limited slip and not a gov-loc.

I don't remember brosephs. I did some searching and found this thread with pics and RPO sheet. It was from the '89 for sure, I see the coil over shocks in the one pic. I swore the '90 was LS too. I don't ever recall running a gov-bomb rear.

Hmm, going through that, it seems we never determined if that was factory installed or not. Maybe it was Silvy? Did you get that one from the original owner?

I swear at some point it was determined you had a factory installed limited slip. But maybe it's just been too long and my memory is going.
