Locking Diff


Recommended Posts

In my quest looking for a truck, wondering which trucks come with the locking diff. I am looking at getting a 99 or newer 3/4 tonne. when did they start puuting in the locking diff?

 

Thanks guys!!

 

 

 

 

The locking rear has been available for many years, but is an option (not standard on any model or year). Check the glove box RPO list for "G80".

you can always go aftermarket-- try www.arbusa.com or the new electric locker from Eaton (Tractech). if ur rig does not have a G80, then its likely cheaper and more beefy to go aftermarket.

The G80 was standard in the 2002 model year on the 2500 Suburban and YukonXL.

Also standard on Z71 Suburban & Tahoe. These locking diffs are awesome when there is anything more than 3-4 inches of snow! Very tough to get in trouble.
