Options that increase cab height
Was at a dealership last weekend with 50’ish F250 CCSB’s lined up pretty tight. Was able to see subtle differences in bumper and cab heights across the line. I know wheel/tire size can increase height, but what else? Heavy duty front end option will add s bit per order guide. What else? Do different packages sit differently?
It also might have been my imagination, but it appeared the 2018’s sat a bit higher compared to the 2017’s in the front too. Wasn’t easy to see unless two trucks of different MY with same wheel/tire size were side by side for direct comparison.

I'm interested in the same item. The book says these trucks are 81.5 and my garage is 82 and it doesn't fit. I'm having the door modified but I'm wondering what height would be enough. The dealer offered to lower the suspension but I'm concerned how that will impact the level of the truck when I'm pulling a camper. The rear end of the truck (at least the one I got to bring home for testing) sits higher than the front so I was able to get in half way in before it was obvious it wouldn't clear.

There are several combinations of front spring, for a given cab and engine configuration.
+1 is heavy service front, +2 is snow plow prep, +3 is both together. I don't believe there is is a difference in front height between 250/350, but there is if your a dually and into 450 because of the front axle weight ratings. But the overall height is the difference of all these combinations is at the back of the cab, because of the rake. That is why we see some of the guys using 250 blocks to lower the cab a bit.
the combs above with wheel size, very little difference but yes, a subtle .5" between stock 20 and 18 inch rims.
my 17 F350 Crew Long diesel with 18s is 6' 10" tall at the back of the cab.

In between two ‘18 Lariats, there was a ‘17 KR with same tires (wheels same size but painted of course for KR). The KR was definitely an inch lower in cab and bumper heights. Wondered if the weight of KR niceties made the cab squat a bit.

The tire, leaf springs, and drive train combo is probably the major driver behind the height variations. A 4x2 on three-leaf spring packs with 17" or 18" wheels is one thing, a 4x4 on five-leaf packs with 18" or 20" wheels is something else; I'd estimate as much as a 6" difference in overall height.

According to the Ford dimensions guide, the F-250 sits ever so slightly taller than any other Super Duty. The tires on the most basic Super Duty XL with 17" rims (or any 350 dually) are only 31.5" tall. Trucks with 20" rims have tires that are 34.1" tall. That means a truck with 20" rims sits 1.6" higher off the ground than the base truck or dually. The taller 18" option is 33.2" or a little less than 0.5" lower to the ground than a 20" tire truck.
250's and 350's use the same spring blocks now.
There will be no height difference between a 2017 and 2018 truck.

So the dealer called me today and stated that their truck sits just under 83.5 inches (3/8). That's fine, I guess...I'll open the door up to 84 1/2 and keep the floor clear I spose. They also confirmed that even if they lower the rear end by 2 inches it would void the warranty relating to the rear suspension. That doesn't seem right but now I'm thinking that's not the way to go.

Because it's the truth. Think about it. If you put taller tires, taller spring pack, blocks, larger wheels, a lift of some sort any of these or combination of these will increase height. Anything you do between the Chassis and the pavement can change the height. So you explain to me why my statement is not correct.

I remember another forum member that swapped rear blocks on his F350 to the shorter ones found on an F250. Lowered his rear end about an inch. One would think you could just swap in the taller blocks if warranty work was required. I'm wondering if the repair shop would even notice the difference if they had to work on anything.
