What is G80?
G80 is not its official name from the company, General Motor. Eaton G80 is used due to its order code as locking rear diff. G80 is infamous for offering high-spec superchargers. G80 works by automatically lets a rear-wheel of drive truck to go places which usually reserved for pickup benefitted from four wheel drive. Mainly, G80 locker offers enhanced traction and control which without this capacity the vehicle can’t do the job.
How G80 Works?
During normal condition while driving, G80 functions as the light and limited slip differential. But, when a low-traction condition occurs which causes a greater speed difference of wheel, the flyweight mechanism engage bracket latching in forcing a cam plat against a gear at side. For example, when you drive off the road on a muddy field, one of the rear wheels will start to spin for traction. Then, Eaton G80 rear axle will locks automatically so that both rear wheels can propel the truck out of this muddy condition. Because the diff doesn’t engage any input from the driver, G80 lock when the rear wheel speed difference has reached 120 rpm. At that moment, the diff has able to deliver up to 100% of power in driveline to both the wheels to get the maximum attack. Certainly, 4×4 pickup trucks can also use G80 differential for adding versatility.
Technically, Eaton G80 locker also performs like an open diff until one wheel triggers excessively slip the locking mechanism. Both of rear wheels rotate at the same time providing a better traction than the traditional one. G80 differential also detects wheel slip by engaging some flyweight type governor. When the slip is detected by this mechanism, the clutch system forces a camp plate ramp against a side gear to compress a disc pack. This action leads to the rotation of both rear axle shafts at the same speed.
