'21 Leveling Kit Options

I just ordered a '22 f350 long box 4x4 , and there aren't any '21's in stock to measure. there are several options in leveling kits from 1" to 2 1/2 " . does anyone know what it takes to get dead level ?

Depends on front springs. Lots of threads on this subject. Just remember past 2" the coil springs will bow without adjustable radius arms. The Carli 3.5 gets most trucks level. Which is a 2.5" lift on 20+ trucks.

Sounds like I want 2" then. I don't care if it's a little high in the rear and I don't want to get anymore involved than needed.

All of the F350 diesel DRW trucks I measured on various lots had 3" of rake. 2.5" would make it appear to be dead level. But, when you tow or haul you'll be nose high.

I forgot to say single rear wheel. I'll have air bags so I'm not worried about rear sag.

i seen a new one at a dealer the other day and it hardly had any noticable rake. 2.5" in the front would have it sqautting pretty bad. not sure exactly what options it had

I just leveled my 2020 F350 Cc/lb but its a dually. I used the Readylift 1.5" blocks that go under the coil mount on the axle. I also did Bilstein 5100's front and rear along with castor shims to retain the stock geometry. I ended up with 3/4" of rake total but looking at the truck it looks almost dead level. I also have airbags in the rear to level the truck when I'm hooked to my 5th wheel. I wanted to do the smallest kit I could that would give me room for my 35x12.50r20. I have a Readylift 2.5" kit but decided against it to avoid being nose high.

I think you meant to say the Carli 2.5 lift is a 3.5"+ lift on 2020+ trucks. In 2020 the trucks were lowered 2 inches from 2017-2019 (except Tremor).

On the 2020 front they sit 1/2 inch lower than 19. So heavy service front springs would raise it same as 19 and snow plow 1/2 inch over 2019. This is the diesel.

I would run something like the BDS 2 inch kit with shocks and 1degree caster shims.

Joe, why the difference between snow or heavy service? They’re both max spring rating on F-350 6.7L that isn’t derated?

The springs are 800lbs per inch so 400 extra for heavy service is 1/2 inch and 800 extra for snow plow is 1 inch.

Thats how it was on the 19 and the 20+ should be similar.

They weren't lowered a full 2". They are approximately 1/2" lower up front (Carli calls it 1"), and seem to be closer to 1.5" lower in the rear, compared to the 17-19. The rear block on a 17-19 was 3.25" at its highest point, from what I understand the 20+ use a 2" block.

To the OP, any more than a 2" lift up front will likely make you nose high. Imo 1.5" looks to be the sweet spot as far as a level goes, leaving a small amount of rake, but 2" might get you exactly level.

1 1/2" sounds good. unless the factory winch is going to be heavy enough to set it down a little ? I doubt it though.

My ‘21 with heavy service has the max spring available for an F-350 @ 5,990#’s🤷‍♂️

I’m also at max gross as well for SWR. So assume that your statement is correct if derated?

Edit: I’m actually just curious as Ford doesn’t do a good job providing tech information only “one spring higher based on computer selection” or some ****...

I only looked into the diesels but I understand camper/snowplow option on a gas f350 gets the max 5990 spring. That would sit around a full inch higher than a diesel with snowplow springs.

I dont think the F250 gas camper/snowplow prep gets those. They would be probably 5200 or 5600.


I think the springs are 4400, 4800, 5200, 5600, 5990.
