I put a little bit of drive time on this thing. It's amazing how much better it rides without the stock coils. It drives "flatter??" and turns sharper too even though it's not the "super" version of the axle. If I had to describe it in some sort of technical way, it almost made the REAR ride better although I changed nothing there....as though the difference in spring rate between the front and rear was always fighting itself. The 14.5" brake rotors are the stuff of legends! It might be a little over-braked for such a short, light vehicle but it's not touchy or overly sensitive.....it just slows down! I also have larger rear brakes (2012) so I think they'll play nicely on the next tow.
I feel like the V or X code springs have a similar effect on the Excursion. My stability and confidence towing improved significantly more after changing the front leaf springs than it did from rear spring swap.
I really like this swap for a 2wd tow pig/hauler and the bonus of being able to run late model wheels without spacers is icing on the cake. What years of axles do this?

The rears would be 05-present although without grinding some meat off of the calipers, forget about running 16" wheels. It's not a big deal strength-wise but you won't get core credit from the parts store afterward. I used one from a 2012 for the electric locker - the ability to not run spacers was icing on the cake. This front was off of a 2004 F450 and will be the same from 1999. In 2005, the wider axle was used with the introduction of coil springs. The 1999-2004 is a direct bolt-on as much as a driven 4x4 axle would be. Forget about running wheels smaller than 20's. 18's MIGHT fit with a little bit more caliper bracket grinding than had to be done with these and some minor clearancing of the caliper itself but I have no 18s here to try.
I tow a little bit with this one....but I don't take pictures of all of the loads.
I didn’t know 99-04 F450 (and F550?) front axles were as wide as ‘05-?? F250/350 SRW axles. I’ve got no problem running 20” wheels. Take-off wheels and tires are cheap, especially ‘stock’ tires.
Yes but I want to be right on top of it so I am vaporized in a nanosecond. If you still have my thermometer when it happens, you can measure how hot the lava is as it burns you up.
I shall point it at your smoking heap....And when meet in Heaven, I'll let you how hot you were.

The wheel mounting surface distance with the dually adapters are the same between the F450/550 and F350 DRW but the adapter depth is considerably different and the inner axle tubes (and subsequently the inner axle shafts) are longer. This adds up to a difference of almost 1.5 inches per side. The wheel bearings and stub shafts are the same meaning that everything from the balljoints-out has the same dimensions EXCEPT the brake caliper mounts. The tie rods are different and are F450/550 specific as shown in the pictures (longer AND they say "F450" on them). Note also the spring plates. They are identical but the shock-to-knuckle "C" distance is greater.

One can see the backspacing difference between stock 99-04 wheels on the F350 picture and then compare to the 05-up wheels on the F450 by looking at the tie rod end relationship. The ackerman angle and length of the steering arms appears to be the same on both knuckles although no meauring was done on either. The main importance to me is no more spacers and the tires don't come close to hitting the springs. The tires are flush with the fender and are in perfect alignment with the rears (track width the same front and back)......oh, and they're FINALLY perpendicular to the ground and I can center my steering wheel without completely fornicating-up the whole alignment.
Sure thing. I just drove up the market prices of these axles in your area, huh?
This one came complete with nearly all suspension, brakes, and steering parts for $1100 (free shipping from Alabama). I only had to supply the steering box (32 to 36 spline and 1 1/2" longer pitman), brake lines, and sway bar frame brackets. Those parts came from the "stock parts hoarding shed". Even the shocks came with it. It came with x-codes but I had a set of v's I used instead. I'm selling the x-codes next weekend so that's cool.
Ok, my driveshaft guy finally got to my project this week - so I banged out the last few details on this 4wd conversion.
I used a gas engine (5.4) truck for many of the parts for this swap. One of the differences between this and a 7.3 truck is the bracket/linkage for the manual transfer case shifter. The gasser bracket only has (2) holes and the linkage is shorter.
I added a piece of material to the bracket and made the linkage longer using pieces of steel from the scrap bin.
