What Do These Mean?

[T Loz]

Ok guys I looked it up in the Abbreviation list but there not there.

 

For example , what is GMT900 and 800 and also G80?

Numbers are for 'generations' of trucks. GMT900 is the "new body style" and GMT800 is the "old style"...mind you the changes go much further than just how the body looks.

 

G80 is an RPO code to designate that the vehicle is equipped with a limited slip differential in the rear end.

Wikipedia has the GMT900 listed as "The GMT900 debuted at the 2006 North American International Auto Show, as the next generation full-size pickups and SUVs, and replacements for the GMT800 vehicles. The first GMT900 vehicle is the next-generation Chevrolet Tahoe."

G80 is the locking differential in the trucks and I think it was once an LSD differential for some car.

If you have a Z71....G80 means locker instead of limited slip.
