can anyone tell me the part number for the factory limited slip that came in the 2015 f150s? also, the 9.75 is a 34 spline, correct?

I currently have an open diff and debating between a limited slip and a locker.

 

2015+s do not come with factory limited slips. Only options were/are open diffs or electronic lockers.

 

Funny, I thought my 2015 5.0 3.73 was LSD + E-locker.
I'm gonna look it up.


UPDATE:there's no "L" in the number on the sticker; Don't look good.

didnt know that. would there be anything stopping me from putting a 9.75 limited slip from another year in there? only thing that should matter is that its a 9.75 ring gear and 34 splines, correct?

a friend has a LSD that came out of his 2009 he will sell me cheap
