not sure where to post this but maybe you guys can help me out just curious about who makes the factory limited slip for the 2005 f150 does ford make it or is it like an eaton brand or something else?

 

i think ford makes the limited slip themselves. eaton makes good LSD and the ones that come stock from ford are junk so i doubt ford is getting them from any reputable company if they arent making them themselves

 

I'm running a Ford racing L/S diff. It was a little over 200 bucks and is holding up to over 500 RWHP. So,,,I wouldn't call it junk!
The Eaton is a better diff but it's 500 bucks!
Unless your doing some serious offloading,,,the ford diff will be fine. Unless you have the extra money for the Eaton.

I know Eaton supplies Ford diff's for the Lincoln LS. I know this because I went through 4 of them in six months time, thankfully under warranty. I believe Eaton makes a great product, but they make what they are told to produce, Ford specs just suck.
