2022 TRD Pro increased lift and UCAs?

The 22' pros get slightly more height from the new red UCAs, is that all that is attributing to the lift increase?
I read the lift increase as 1.5" front and .5" rear, but compared to what? a 21' pro? or a 22' SR5?
What is the overall increase from the 21 pro?

I'd like to get the UCAs on my 21, but is there more to it? I'm sure the grill sensor placement has to have been adjusted as well in the new pro grille.

 

The upper control arms would have no impact on the ride height. It is all in the springs and shocks.
The lift increase is compared to the lowest non-Pro model (37 mm [1.46 in] higher than a 2.7L model with Firm Suspension in the front), other models are similar except the Trail Package.
The grille sensor and placement has not changed at all from 2021 to 2022.

super informative, thank you Jeff.
What would be the lift increase compared to a 2021 pro? it sounds less significant than i thought.

 

Based on the info provided, if the prior year Pros are only an inch higher in the front when compared to the base models, then the 2022 Pros are just 0.5" taller in the front/rear than prior year Pros.
