So I found the Ford number for a '19' 4000# spring. it is F81A-5310-ACD, and then another number, 5C3Z-5310-HA. Says for an 05 to 19 superduty. I don't have enough experience to know if they will go on a 2020.
They will fit. A quick search using those part#'s looks like the F81A- is for a 4wd and the 5C3Z- for 2wd. What are the details of the leveling kit you have?

The leveling kit is the 1.5” little tapered block that goes under the shock mount that is on the axle.

You could probably add those 4000 springs but with the leveling kit it may need some caster adjustments.

Do that and add new shocks and check for any worn parts.

Adjust the tire pressure too.

I think if you have the 4400 LB front GAWR, 10000 LB GVWR springs. Those are the lowest rated OE springs for your/our trucks.

I guess i'll look into a shock change. I just recently got this pickup. It has 50k miles, and I have to say, I am not at all happy with the ride quality. I specifically tried to find a 2020 F250 without the snow plow prep for the purpous of a better ride, and this not what I would consider decent. I traded a 2006 F250 on this, and the 2006 was far better. Ive got a 2011 diesel and a 2000 F350 with 270,000 miles and both ride better.

As far as shocks, I've heard Fox 2.0, Bilstiens, and Rancho 9000s. What is gonna be the best. Im not concerned with Off roading. The road conditions im mostly concerned with are cracked, jointed oil roads, and washboard on gravel roads.

Shouldn't be tapered but sounds like it just has coil spring spacers. No bump stop extensions or shock extensions that might cause earlier bottom out.

I would be skeptical of shocks alone magically transforming the ride but I did replace shocks once on the rear of a Tacoma that were so bad they were nearly seized up.

Larger tires with more and softer side walls at lower air pressures are going to yield you the most ride change. Most aftermarket shocks are just going to stiffen the ride ever more.

Its got 285's on it now. The bump stops are stock, so with the leveling blocks, there should actually be more travel clearance.
And the things is super clean and been well taken care of. Seizing shocks shouldn't be a problem.

I joked a bit about not having acces to a custom spring shop, but I would be receptive to a reputable online spring source for a custom coil spring if there is such a thing.

Well, not sure what it could be. With 4400lb coils, good shocks, appropriate tire pressures, "harsh" is not what it should be. I have seen a couple posts recently from other owners saying their SD is the worst riding truck they ever owned......but then you'll find owners with plow prep springs not bothered by the ride in the least.

I'll play with tire inflation at various pressures and see whether I can improve things a bit. Just am really disappointed in ride quality. Of coarse when you take it out and test drive it, the roads were all decent shape, and no dirt roads. And then you bring it home and drive it on the roads you drive every day and it just breaks your spirit.

And I don't even own a half ton pickup, so my comparison is apples to apples, or at least I thought it was!

My 2020 F250 KR Super Crew 4X4 diesel bottoms out on the bump stops frequently at speed when going over bridge transitions and such and sets off the dash cam - hence what I would also call a "harsh ride" on the front axle. Have tried Rancho 9000 adjustable shocks, 295 front tires at relatively low inflation and while helpful, the next step is actually a slightly taller front coil to add some travel. If this doesn't provide some relief, maybe a Carli Commuter. Love the truck; the roads around here are just a bit much.

Did you add the leveling blocks at time of purchase or did you find its stock set up (without leveling) harsh as well? Leveling blocks may seem trivial but they do alter the weight distribution between front and rear.
