What do you want to achieve? Keep it simple and clear!
I want to know if there is anyway I can get Posi-Traction or a locked/welded differential on my A-Chassis vehicle so the wheels don’t spin as soon as they come off the ground. -
What is the issue? Include screenshots / videos if possible!

That video shows what I’m taking about. Going up a ramp and then the wheels that are not touching a surface just spins causing me to get stuck, versus if i had a Posi-Trac, welded, or locked differential it would make me not get stuck. -
What solutions have you tried so far? Did you look for solutions on the Developer Hub?
I tried to mess around with different sections of the A-Chassis script but nothing seems to work for me. I looked high and low for an answer to this but no one seemed to have asked before
After that, you should include more details if you have any. Try to make your topic as descriptive as possible, so that it’s easier for people to help you!
