Differentials

[03greenZ]

I was wondering what the sizes of the differentials were in the 03 Z71. I was considering the Eaton E-locker.

Hey,

I think all 1/2 tons take the 10 bolt in the rear. You probably also have 3.73s for 4.10s. Good luck with the locker.

Here's some diff pumpking gasket profiles to help tell which you have.
