Pickup trucks and 4-wheel-drive often go together like peanut butter and jelly, but what if you don’t want the added cost and weight of a 4WD option in your new pickup truck?
GM says it has the answer, and that answer is checking the G80 order code on your next new Silverado or Colorado pickup.
The G80 order code gets you an automatic locking axle that GM says increases traction in all kinds of low traction terrain.
“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,” said Jeff Luke, executive chief engineer. “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.”
The video below shows just how the G80 automatic locking axle option works.
According to GM ,”The G80 automatic locking rear axle is available on most Silverado models, and is standard on LTZ and Z71 versions of the Silverado 1500 and all Silverado 2500 and 3500 HDs. Additionally, it is available on Colorado WT and LT models, and standard on Colorado Z71. It is also standard on Tahoe and Suburban.”
TFL has yet to test the benefits of the G80 order code, but you can bet that as soon as we get our hands on a GM truck equipped with the rear axle lock, we will test in the the Rocky Mountains.
4WD trucks tend to be more expensive and heavier which decreases towing ability. It will be interesting to see if the G80 rear axle lock option is a viable alternative to 4WD off-road package, or just a better addition to a new 4WD or 2WD truck.
