I have a 2003 Ford F 150, Super Crew, 2WD,with a L/S diff, I wanted to know if I can put a locker in my diff? I do not do very much off roading except during hunting season, I usually take my atv on a trailer if conditions are muddy or snow is present because I would probably get stuck if I just took my truck. I don't have a problem with the $750 plus price tag of the Eaton E locker, my question is, will it assist my truck dramatically>I do not know anything about differentials, or transmissions so you will have to dumb it down for me.

you could do the locker but if you dont off road ever, i would just pick up a posi trac carriage from a junk yard and swap that in.

What's the difference between the too?

would a Detroit locker (automatic) be better than a selectable locker? It is cheaper, but does either work as a limited slip when not "locked"? My truck has a 9.75" gear and is a 3.55 L/S ford rear end, Ive never had the guts to really test it in a slightly muddy field to retrieve an animal, and I only have all season radials on it, I plan on getting more aggressive tires on the rear, Ive never had ne problems on icy or snowy hwys, I just drive sensibly but pulling off into a field that's soft is another story.

If you have a limited slip now you will have to have a new carrier to put in a locker, they go in place of the spider gears.

I think that for your intended use "driving across a muddy field" you would see very little if any difference. You currently have a LS 9.75" diff. this is the limited slip hence LS. In mud the E locker, or a detroit tru trac or any of the "lunchbox" lockers are all going to behave similiar to what you currently have.

Big difference is on gravel, dry dirt where one tire is slipping on rocks etc., and the other HAS TRACTION.

Unless your LS is wore out, in mud your current setup should spin both tires which is what would happen with any of the other lockers, or even a spool. Better tires would do more for you than swapping out the LS.

A Detroit Locker is a little radical for everyday street use. It will drag a tire on wet roads, etc. Plus, a Detroit will not break a tire loose once it is locked up causing a broken axle instead of letting a tire spin. The E-Locker is the way to go that way it is ON or OFF. The factory E-Locker kicks its self out a 35mph, then your back to a open diff.

Agreed, but snapping an axle in a full size truck is a great story to tell....

You can start it out like all of the great sea stories ..... No s**t you are never going to belive this AJ got this 23 point monster buck that weighed 2000 lbs and while driving across the field to get it he slid sideways cause a his detroit locker....got the tire wrapped up in the frame of a deserted k1500 that he ran over and snapped his axle all to heck
