Uh, no, the outside diameter of the various Lightning models with 18", 20" and 22" wheels is exactly the same. The only difference is tire profile (there is less sidewall height on 22" wheels than on 18" wheels, but the diameter is the same).
I understand what you are saying - 275/65 R18, 275/55 R20 and 275/45 R22 are all about 32" in outside tread diameter. I referred to several tire sites for Lightning Tire sizes. The 20" tire size listed for the Lightning is 275/60R20 which has an outside tread diameter of 33". That is where the height of the truck will be 1" lower.
32 vs 33 diameter will result in 1/2 inch height change (only half of the diameter is from the ground to the axle center). The 18s will lower the truck a bit, but to get any significant lowering some suspension changes will be required.
Correct. My error. Good thing OP only needs 3/8" lower height.
Do you have a link to the belltech part or part #?Belltech makes a direct fit strut for a 2013 f150 that utilizes the factory spring and fits the rear of our lightnings for 1-3" drop. I used them on my lightning for a while and ride was same as stock. Recently switched to a different setup to get even lower though. As of yesterday swapped all the parts from the white truck to the black platinum.
Damn man that looks super clean. Any parts or install info? I'd love to mirror the look.Belltech makes a direct fit strut for a 2013 f150 that utilizes the factory spring and fits the rear of our lightnings for 1-3" drop.

Belltech part no: 25001 for the rear
I've got belltech 25027 on the front and for the rear I've got "ride tech shockwave hq" air struts with a "wireless one" ride height control kit
That seems unlikely. The spare on my Platinum is smaller than the other wheels. If all Lightnings were the same size I would expect the spare to be the same as well.
this is fact. The only difference in diameters is the wheel itself. This is true of almost all auto manufacturers. When my Tesla had a 19” or 21” wheel option, the outside tire diameter remained the same. That s that same for my Platinum Lightning vs the various other versions. My 22” wheels just have shorter sidewalls and bigger wheels, same diameter tires.
