Input welcome, especially @Zengineer .....
I'm curious to understand what, if anything, Ford does to adjust the pinion angle difference between similar 2WD vs 4WD configurations (it being suggested that the former would have no block, while the latter does).
My scenario - I have a 2022 4WD 145"WB Lariat 500A SCAB w/Max TT Pkg., 7050# GVWR, the 3-leaf spring pack
IF I compared my truck to a 2WD 145"WB SCAB (comparable in all other respects but presumably without the block), what components would be different, if any, aimed at 'correcting' the 'no-block pinion angle'?
Would the axle-to-bump-stop distance be ~4.55" on that 2WD truck (IOW, would it have the same bump-stop component)?

I wouldn't mind lowering the rear of my truck by ~1.2" at the axle. I do tow a 5500#GTW 5th wheel trailer which, when loaded for travel including the hitch weight, imposes ~850# load in the bed (against a rated payload of 1848#). My typical 'other cargo and occupants' weight including myself is ~250# in the cabin. The 'static sag' at the rear axle when all that load is applied is ~.75"~1".
With block-removal I'd sacrifice ~1.2" total worst-case 'bump-travel'; the impact on front caster and pinion angle seem inconsequential in my case?
Am I off base, are there other implications that I'm missing?
Thanks in Advance for y'all's thoughts / input

- One-piece driveshaft length (CL to CL of U-joint) = ~72"
- Block thickness = ~1.2"
- Axle to bump-stop, unladen at rest = ~5.75"
