2014 Ultimate LSD

Did all of the 2014 Ultimates come with an LSD?

Just read about the 3.91 rear gear swap and doing some research. I've left my car stock since buying it 2 years ago, but getting the urge to bump things up a bit. (Need an exhaust and better intake first).

Is there a list of compatible sources for the 3.91 ring and pinion? I would imagine it was used in other Hyundais besides just the coupes.

duck under the back of the car.....

Diff will have a label saying the gear ratio and whether it's standard (std) or limited slip (LSD)

All gear ratios are compatible with both STD, and LSD. The 3.8L sedans got the 3.91 ratio, and STD diff.

5.0 sedan got the lsd IIRC.

as far as swapping gear ratios, people say that they are interchangeable. But with how ring and pinion gears work and not having experience with swapping it on this car, I don't want to give a definitive yes.....

Plus it's just easier to change out the whole diff. you can swap the pumpkin (diff without the carrier/housing) just fine.
