It is stock height. Ended up using stock height shocks for the F-250/350 since there is no specific stock height monotube listings for the F-450s. Rear # 985-24-151, Front # 985-24-154
Note they do not come with boots to cover the shafts so if you run gravel you'll want to source shields or boots. They chloride the roads here in the winter so I threw on some Rancho boots that I had around to protect the chrome shafts from the spray.

Is your 450 stock height? If so would you mind sharing part numbers for the fox shocks. I replaced the factory shocks at 30k with Bilstein 5100's which are ok for now. I am the worst demographic as I go from unloaded daily driving to towing our 18k rv to a 20-25k equipment load. I'm looking for something to calm the bottoming out when loaded exactly as you described. The long wheel base of the 450 amplifies those hits when towing in my opinion. Thanks in advance.
Have had both and the fox is more in control of the springs unloaded “feel”. The 4600 dampens what you are describing. If you are lifted the 5100 is the part you need.
The first thing I do on our work trucks is put 4600s on them.
I have used my personal trucks to tow heavy too, which I trick out and the fox 2.0 is fine as well.
Not to get into a twin vs mono tube debate but the rancho 9000 on my DRW I adjust. I snagged a conventional pull trailer yesterday to pick up a skid steer total around 14,000 and the coupler was adjusted for a taller 4x4 we use and was bouncy as it was nose down. Adjusted the shocks real quick for the 36 mile drive (after driving it a couple miles) and it helped some; but I did have to adjust the coupler asap when making a real stop.

This is good stuff on the Fox shocks. I've got a Fox 2.0 steering damper (stock tuck) that has been installed for 3 years. I've not been nice to it. I'm debating replacing with a Bilstein or rebuilding the Fox. It does have the nitrogren schrader valve on it.

it probally needs nitrogen.
me personally would put official shock float oil in it per fox instructions which is about 30cc. Then tweak with very small amounts of nitrogen.
