i was talkin to some guys and 2 speed diffs came up so i was lookin for them and i cant find much anyone know anything?

 

2 speed diffs are pretty much for heavy trucks only with a 15 to 20+ inch ring gear!

I drove a gas truck for a while in college and it had one, 4 spd tranny and a pull knob on the shifter for the diff gears. It would be a cool concept for a 4x4 but on a large scale

 

I've allways wondered if these were out there. Learn something every day.

 

some guys say trail gear sells something like that but so far i cant findem
