Axle code?

[Codeman96]

The axle code on the option tag for my Sub shows a 1GQ1? When I look this up on any RPO codes it shows standard ratio but no #s. I am assuming that would be 3.42s? Any help? I know they suck just curious as to what they are for sure before I switch to 3/4 axles and 4.10s.

Holy crap I was doing some searching the mysterious "1GQ1". It is a joke as far as being specific isn't it?

My 90 3/4 ton burb came with 3.42s. I don't know what RPO code it has.
