Rear End

I have a kinda stupid question. Which, if any, S-10s came with a limited slip differential. My room mate said his 01 has one and I don't believe him.

Lots of trucks come with limited slip rear ends. Call a dealership with the last 8 digits of his vin and they will be able to tell you.

Look in the glove box at the decal with the list of RPO Codes. G80 is the factory locker (not a limited slip) that is in my wifes 2001 S10. If G80 is not on the listed then it's not on the truck.
