I have a 2014 f150 5.0 2wd with 3.31 e locker. I don’t believe I have a limited slip differential. The axle code is L3. I understand that I do not need the friction modifier additive. What gasket will work the best?
 
There are two rear ends possible an 8.8 or a 9.75. You can tell the difference by the shape of the rear cover.

This is an 8.8.

This is a 9.75.

RTV Gasket Maker or Lubelocker. Never Fel-Pro. Tried that once and it leaked like a sieve. RTV and it hasn't leaked in 70k miles.
