I have a new used diff among the other things changed out now that mods are under way.
I'm wondering whether or not I've got a LSD. The gears feel shorter to me and my 70 mph RPM seems higher. My mechanic got this and he had several to chose from but he would have to research the code # he got.
I was sure somebody here could tell me in a few minutes what the code would say to indicate LSD.

Here's my exhaust system now. Feels way faster and a hellava lot louder.
The 4-1 Stahl header from 2002, no cat, Magnaflow resonator where cat was. 2" exhaust Magnaflow straight through muffler, no tip.

On the LSD there should be a "S" stamped on the diff, on the sides i think.

just spin the tires while the car is lifted. if both spin the same direction, you have an lsd.
