From two other threads discussing the parts catalog and real-world info from the 4WP team... here's what I think is going on with the suspension components:
The Ford parts catalog does indeed list three separate suspension called "Standard," "Special" and "High Ride" with images that that correspond to Base-OB, BL, and Sas shocks we've seen in public.
Base - OB shocks have a typical range of motion, and actually don't allow the wheels to drop as far as the position sensitive bilstiens. Following a discussion in another thread, this means a "level/budget" lift of spacers is fine if someone wants to add larger tires.
BL / Sas shocks allow for greater range of motion / more drop. They are actually maximized for the platform and at full drop the CV angle is maxed out. Therefore a "level/budget" lift will cause CV problems at max drop.
If you want to quickly/most cheaply raise a BL or Sas height and you don't want to lose range of motion, you'd need to change something about the springs (length, perch, etc)... basically raising where the vehicle sits at rest within its normal range. This will not effect max drop or impact CV.
You could do the budget lift, but you'd have to limit downward travel by the same amount (by adding straps or something) to protect the CV's... but that's limiting travel.
As a result, I suspect that if you want to turn your BL setup into a Sas height, you'll probably need to do the spring adjustment listed above, and then add a spacer to limit compression so you don't get interference with the 35" tire at compression.
This actually jives with the Ford rep stating there is a 10mm "spacer" and the other stating it's 10mm "higher" on the sas than the BL.... what they meant was the shock spindle is 10mm longer on the Sas, raising the vehicle by that much, but then there is also an equivalent decreased range of motion / articulation which has also been mentioned to protect the CVs.
This could be the reason why there are different shock parts and BL is said to have the greatest articulation of all trims.
