Axle ratio?

Since I bought my expy used, how can be certain what gear ratio I have and what type of axles the truck has? I'm thinking of adding lockers front and rear. Would this be a good or bad idea?


Thanks

Axle ratio?

Look inside the driver's side door.

Axle Codes:
19-3.55 non-limited slip
17-3.31 non-limited slip
H9-3.55 limited slip
H7-3.31 limited slip
H6-3.73 limited slip

I don't know why you'd want to install lockers unless you use the vehicle in very rough, slick, sloppy terrain. Sure they are cool but do you really need them? Only you can answer that question.

Thanks for the information. Turns out I've got the 3.73 limited slip
rear end...

Thanks again
