'77 F100 Rearend

I've read that positive lock differentials are dangerous for daily drivers. I have a '77 F100 without positive traction. I'm having the gears changed from 2.75 to 3.50. I would like to have positive traction. what would be the best, least exspensive, and safest way to do this without changing the entire axle. Or is changing the entire axle the best way to go?

A posi traction rear end still staggers the wheels speeds around corners....there are clutches or other devices in there to do that.....I think you are referring to a spool rear end when you heard about not being safe,,,,,That is a device that totally locks the 2 rear wheels together, not allowing different wheel speeds for cornering. Those are used mainly on drag racers.

The old limited slip rear ends make winter driving on icy road a real challenge. Dry pavement not so big a deal.

I've sold a few Duragrip differentials for the 9 inch Ford lately and I just installed one in my Camaro last week. So far it's working great. These are MUCH stronger than the original Ford Traction Lock. A little bit of grinding inside the case is required sometimes for clearance of the thicker clutch cover on the Duragrip.
