It moves the sensor position 1.5"

It still has the same range of motion, although you move the top and bottom.

The lift rods give you 1.5 inches full time and in the off road mode will go partially into the extended mode. If you get high centered, it can still go a bit higher.
33 inches it the max I normally recommend, you may get some very minor rub with 33.2 but it can be adjusted for.

So I think the KO2s look great! Question: many of the photos have the KOs on 20" rims. If you get a 1.5" lift on 20"s, is it possible to get a smaller lift and switch to an 18" rim? Is it one of those problems where you need the 20"s for the brake calipers on a P400?

 

Lucky8 sells a rear brake caliper swap that allows some 18” wheels on the P400. The front brakes fit just fine, the rear caliper must either be ground down or swapped. The replacement calipers are LR calipers using the same pad and piston size, so it really begs the question why the rear caliper was designed to be so bulky.
