Yes, as Mike has said, all of the 4X4 EXs have the same suspensions (with only slightly heavier front springs on the PSD rig as they are a bit heavier) so the same upgrades with pickup spring swaps work on both PSD and gasser EXs.
ALL PSD EXs came with 3.73 gears, as that is what works best to keep the diesels in their happy place while cruising. The V-10 rigs had a standard 3.73 gear with the option of 4.30, if you are building a gas tow pig you will want the 4.30s with stock sized tires.
On the door jamb sticker it will have the gear ratio shown under the "Axle" header (although some early EXs were missing this code....) 3.73 non-LS = "31", 3.73 LS = C1 and 4.30 LS = C3.
In my experience with the 6.8 the deeper gears helped in ALL towing situations. We made the same trip from/to Philly and Savannah while towing the old 9500lb TH with the stock 3.73 gears and again with the 4.88s installed. Both trips had the same 32" tires, same trailer and weight, same route, same speed etc.... This trip is about as flat of a long run as you will have here along the East Coast with only rolling hills in MD and VA. With the 3.73 we saw 6 to 7 MPG and several downshifts out of OD on those rolling hills, following the change to 4.88s (and no other changes) we got a solid 9 MPG and didn't downshift a single time while cruising on the Interstates. No big hills and no stop & go and it had much improved power application and a substantial bump in MPGs.

 

 

You could just swap the ring and pinion and be done with it. Ring and pinion sets run about $325-400. I can install for you if you are still here in TX. The other option is to get an axle from a F250/350 that had a 5.4L engine in it. Then you are pretty much guaranteed to get that gear ratio (4.30).

 

 

I would call them and ask them to text you a picture of the tag on the actual axle itself. Or, they could print the build sheet from the VIN and tell you that way.

Is $13k in your budget? If so, there are better trucks/prices out there than that.

What features are your must haves? 4x4? Leather? Cloth? Diesel or Gas?

Not a private seller, but price is right:

I prefer to deal with private owners all day every day. You will get more info on the vehicle, and you will have more bargaining power with a private seller.

 

 

In regards to the 6.uh-oh:

Do you work on your own vehicle? Have tools? Have you ever owned a diesel? Are you willing to put the effort and energy into learning all about that engine and its shortcomings that need to be addressed?

A 7.3L is a MUCH safer bet for a first time diesel owner. Very forgiving and easy to work on. The 6.uh-oh is not forgiving, and it is not easy to work on. The wheels on it have been changed to 18", so that guy is running spacers on it if he has a brain, but looking at the photos I ain't so sure. I noticed the spare is still a 16"...arm rest missing in second row...

In regards to the V-10:

It is 2wd. Can you live with that? For the miles and interior condition, that is a good price at $7500. You need to pull the history report on it, and really, really check the underside for rust. If there is any rust, re-evaluate.

 

The last V10 posted seems pretty decent.

 

Give me details. I cant pm anyone. Dont have permission. 😩

 

You will after today.
