    I have a non posi rear end in my 01 Silverado. What aftermarket options would be good
    for replacing the rear diff (only) with an electric locker...???the front would stay as is...

    Eaton makes the G80 (auto locker) which is an optional feature or you could go with their full time posi that throws out in corners.

    Eaton also makes an electric locker. Personally I think they are still having problems with it. For your truck either the standard Eaton Auburn style posi or if you prefer an ARB air locker. If you don't do hard core wheeling the regular Eaton Auburn posi works fine. Steer clear of the G-80. JMO
