On the 'Service Parts Identification' card in the glove box, the option number is 'GT 5 - Rear axle - 4.56 RAT'. I know the 4.56 are the gears, but what is the 'RAT'?

TIA!!

Just a guess, but it's probably short for RATIO..............as in gear ratio...............but that's just a guess!!!!!!

GT5 is generally the code for 4.10s, though. Maybe you have some sort of special edition diff!!!!!!

Where does that code show up, Sara? Is it in the actual option list, or is it somewhere else on the sticker? All RPO codes are three digits/letter long............

I was thinking it had something to do with a locker or something.
