How does a locking differential work
Pickup trucks are built to be one of the most flexible vehicle platforms available. This means that they will have to travel where the roads are more like trails or at times when the road surface is less-than-ideal. For many people, the quick answer for dealing with those kinds of situations is simply activating the four-wheel drive and going about their business. However, not every person has the need to have four-wheel drive because of the way they use their trucks, this doesn’t mean they are left to fend for themselves when the road starts to get a little rough. The G80 automatic locking rear axle is standard on most versions of the 2015 Chevy Silverado available at Don Wheaton, including the heavy duty 2500 and 3500 models.
First of all, don’t get intimidated by the term “G80 automatic locking rear axle” or its synonym locking rear differential. We are going to explain how the system works so you can better understand your Chevy Silverado and get the most use possible from it. Just so you know, G80 is the order code of the locking rear differential, its not some instance of automotive jargon meant to frighten people that don’t know about these things.
“The G80 locking axle provides a greater traction advantage than limited-slip differentials in most situations, while its automatic engagement requires no driver involvement, unlike some competitors’ electronic lockers, which require driver activation,” Jeff Luke, executive chief engineer said in a Chevy Press Release. “The G80’s simplicity, durability and sure-footed grip have been proven with generations of customers, as it has been a staple of the Chevy truck lineup for more than 40 years.”
So how does a locking differential work? If you have ever driven through snow or mud, you may have encountered a situation where you got stuck and when you stepped on the accelerator, one wheel spun fast and the other didn’t move. With the G80 automatic locking rear axle, the components are built so when the previously mentioned situation occurs, the axle engages the system to apply torque directly to the spinning wheel to give it extra traction. Many Chevy competitors require the drive to lock the differential manually. The flywheel governor design of the G80 allows the differential to lock and subsequently unlock without driver doing anything or even knowing its happening.
Wheaton customers looking for this kind of capability can find it as standard equipment on the Silverado LTZ trim and with the Z71 package (this includes the Chevy Colorado Z71 as well). The G80 locking axle can be ordered as additional equipment for the WT and LT trim models of the 2015 Chevy Silverado.
