The Chevy G80 differential, known as a limited-slip differential, doesn't have a fixed gear ratio itself, as the gear ratio depends on the specific axle configuration it is paired with. Common gear ratios for Chevy differentials range from 3.08 to 4.10, among others. To determine the exact gear ratio for a particular vehicle equipped with a G80 differential, you would need to check the vehicle's specifications or the axle tag.
The codes GU6 and G80 are for the gear ratio on your vehicle the G80 code indicates your vehicle was eqipped from the factory with a locking rear differential and the GU6 code indicates your gear ratio.
