Limited slip rear axle on the 90 K5 Blazer

[Ralph the german]

Hello friends and a merry christmas,

one question ; is from factory build always a limited slip rear axle on my `90 Chevy Blazer K5 4WD or was it an option. Don`t know it or had a look inside the rear. What kind of locker is there in ?

Thanks

All I know is on my 91 the glovebox sticker has code G80 which means it's the LSD, but on my 90 it's open (but I have no sticker) so I think it might be an optional item?

Optional. The option code in the glovebox is G80. It's actually an automatic locker and locks the rear end solid when you get ~200rpm difference between tires.

yes thanks, that is what I searched.
