Don't waste money on FXjoke4. The front springs and shocks are crap, and all you really get are cheap skids, a button and stickers. My last truck a 16 Lariat had the FX4 package and the ride was mushy, sloppy, nose dived at every stop, and now I have an 18 plat without FX4 and the ride is so much better, handles so much better, and doesn't try to dig a hole in the ground when stopping. If you want the 3.55 9.75 axles order it. Code is L9. Comes standard with Max Tow, but you have to buy it as a separate option on the V8.
I expect a 60k plus Platinum would ride better by design verses a XLT but that's just a guess. I'd be disappointed if it didn't. I respect other peoples comments and opinions. This is just my experience with one particular truck...Pat

All 3.5L EcoBoost trucks without MaxTow and without 3.73 gears have an 8.8 axle.
If you want the 9.75 axle, the best way to get it is by finding (or ordering) a truck with the Max Tow Package with the 3.5L EcoBoost option. This gets you the L9 - 9.75 rear axle with 3.55 gears, the 36 gallon fuel tank, and a rest of the stuff that is in the standard tow package. All 3.5L EcoBoost trucks without MaxTow and without 3.73 gears have an 8.8 axle.
If you want a 5.0L Coyote V8, then you must order the 3.73 gears to get the L9 - 9.75 rear axle which includes e-locker.
FX4 only gets you a different set of front shocks, skid plates, e-locker, (cheap and thin) skid plates, hill descent control, and all terrain tires. All of which (except e-Locker) can be added to the truck in from the aftermarket and all of it factory equivelent or better quality. And if you get the 9.75" rear axle, you have the e-locker built in as a part of that rear differential automatically. I won't say not to get the FX4 package (as I have it on my truck and like it) but if you are into hard core off roading, it will not help you in the long run and these pieces will have to be replaced with heavier duty options.

F250 does not get the lane keep assist due to a different steering system - otherwise I would have it ordered instead. The F150 I have configured should come in at 1900lbs or better payload based on my research and end up at 2000lbs once I finish stripping off parts. I only need 1750lbs payload for what I am doing at this time but you never know when travelling what you may pick up along the way at the antique stores. My trailer is well within the tow specs of 9100lbs but when you add up the tongue weight, people, cargo, tow equipment, etc... I am at 1750lbs. Payload is always the weak spot when pulling a camper.

To directly answer the OP. The ONLY way to get a 9.75 with a 5.0 is HDPP or 3.73. Since the HDPP comes with a 3.73 you can simplify it to the only way to get a 9.75 on a 5.0 is with a 3.73. The FX4 package is irrelevant.

This has been better answered in other threads, but all 2.7 payload package, 3.0 powerstroke, and 3.5 Ecoboost have the 9.75 iirc. The 5.0s only get it in certain configurations. The fx4 doesn't affect it. Pretty sure it's also been verified that the fx4 doesn't change shocks or springs either in this gen truck. ETA: front shocks are different, rear are not.

To the best of my knowledge the FX4 has a different part number for the front shocks. The rears are the same part number as non-FX4.
That said my 2018 FX4 53B is the best riding truck I've ever been in. I honestly think my Buddies non-FX4 53A rides worse. I'm not sure if it's his Shocks or the Solid Front Swaybar.
