I have a 4wd 04f150. I want to lock the rear end. Mine does not have limit slip and I want the rear end to lock, I was thinking along the lines of DGL or a Lunch Box Style Locker.

 

do NOT use a lunch box locker... omg i HATE mine with a passion. i tore it out 3 f'n times trying to FIX it and it was fruitless. this last time it went the meshing surfaces warped from the stress of a wore out 4.6 with almost 200k miles. meaning the cog teeth will not mesh, not driving the truck...
wanna know how many miles?

appx 13k


i just bought a detroit locker for $600 for my 8.8" axle and its backed by the legendary performance guarantee from detroit gears. you know the name for its durable as it gets products. i have pics in my f150 album.
