Adding a limited slip to my 3.31 open?
on a 2016 f150 2wd 2.7ecoboost
gonnah keep the gears. 90% of my driving is on the interstate. but the open diff is not gonnah work. not on this light *** truck with its aluminum bed. not living in the mountains where i almost get stuck making a downhill u-turn.
im looking at lsd options and have decided to go with auburn hp for 8.8 31 spline
1. will this fit?
2. have there been any detailed install writeups? (searched for over an hour)
3. should i go with the positrac oem lsd? its 200$ less
im hoping i can do this. i installed new shocks/springs/shackles/intake on this truck already.

There is the factory e-locker which I thought was made by eaton. Have you checked that out?

Ford beefed up the pinion on the newer 8.8's, but I didn't think they changed the carrier bearings or axles. If I were you I would start comparing part numbers on the bearings between the older & newer 8.8's.If the carrier bearings have the same ID, and the axles are 31 spline, there's no reason you couldn't drop a TruTrac in there.
