Screw drive line?
 

Maybe this already has been created or thought up but what about having your drive line with a screw shape to pull the truck up as it's getting hung up on a sharp edge? So it would look like the middle part of a lag bolt if you are trying to picture it. Maybe it would only be needed for the outer or female part of the drive line.


Also is this legal for comp?

Hummm.....got any pictures (or drawings) of your idea?

I think he means shaping his driveshafts like an auger.
Probably not comp legal.:lol:

The rules state the that the rig may only be driven by 4 wheels.

2.1.1 Vehicles are limited to 4-wheeled vehicles only. These 4 wheels can be the only source of
propulsion for the vehicle.

Buddy of mine thought about square driveshafts at least then you would get pushed off or up rather then hung up.

Hey, about the square idea.
People in my 1:1 club used them because theyre a cheap temporary fix, and believe it or not, he was hung up and that thing moved his huge a$$ all the way over off the top of the rock.
I would have not believed it if i hadn't seen it.
