I searched G80, g80, G-80, and g-80 and the site turned up no results.
I know that G80 is the Eaton locking differential, but that's all I know. I would like for someone to describe what it does and why I should want one. (when I google search I don't come up with much either)
Other questions I have :
What does it cost on average?
How easy is it to swap?
