Not a good idea. This doesn't give you a posi. It gives you a completely solid axle. No good at all for a street driven vehicle.

That would make your truck almost impossible to drive safely in adverse weather conditions!!!

Geez, do NOT do that! At the very least, you'll break the axle after turning a corner a few times. Sounds like you want to make a "poor man's spool."

Spools are strictly off-road use and/or racing. Never, ever on the street.

I bought a brand new 1985 Ford F-350 cornbinder chassis cab 2WD. It came with an open Dana, so I put in a Detroit Locker. If you don't know how the Detroit Locker works, it basically locks the axle ALL THE TIME.

When you go round a corner, there is an "overrun" ramp that disengages the slow wheel. The disengagement is quite harsh and noisy: CLANK CLANK CLANK CLANK. Folks expect to see parts on the ground when they hear this, but it's perfectly normal and causes no axle damage.

In winter 1986, I had to pick up a couple of skidder tires at the local tire shop, so I drove in empty. There is a long steep hill on the highway near the tire shop, and it had snowed good, so snow/ice on the hill.

I was going about 40 MPH when suddenly the rear end swung out. In an instant I was sideways, spun like a top, and thankfully came to rest on the highway and right side up.

I had to change my drawers (Well, DUH), went to pick up the skidder tires, and carried on. With a full load (+5,000 lbs) the thing had great traction and was very safe. Empty, I never drove it in winter again.

The factory G80 GovLok is quite safe in this respect: any speed over about 20 MPH, the flyweight governer assembly latches out so the axle can NOT lock: it functions as an open axle.

Put in something like a PowerTrax NoSlip and be done with it
