Question posi rear end

I was wondering if I could make my rear end a posi. Someone told me you can weld the spider gears together to make it a posi. Its a 75' ford f100, and I would like to make it posi if that is all it takes.

That is called a Lincoln locker after the welder company. It does not make it a locker. It is similar to putting a spool in. It is dangerous to run a spool on the street.

posi is the same thing as "limited slip". Posi is a chevy term, limited slip is a ford term. Check out howstuffworks.com and look for the axle stuff, it'll give you a good explanation of how they work.

Welding spider gears is not a very safe method no matter how good you can weld. I have heard horror stories of these exploding in mud trucks.

check your trucks printed axle code (driver side door jam). i've been researching the same for my '77 F-100. looks like several mfr's make a manual activated kit. search the net for 'ford manual locker'. also found some at www.truckperformance.com

by the way, there are Code Braker sites on the net also
