I have stock diffs would like to upgrade them. any suggestions I want to do some off-roading and would like to navigate the Tourane as seamlessly as possible. gears, lockers, axels ?

 

Straight axle swap is the only real "upgrade" for them! Other than that you can get an lsd for the rear but not much for the front.

 

lsd sounds like an economical way to go. were would I get straight axles from. after market junkyard?

 

Just google "SFA S10" or "SAS S10" and you will find more info than you will know what to do with!
