No need for an alignment. No need to reaim headlights. There is no lift. Just a reduction in suspension range of movement. Look at the photo. The car sits level still. No actual lift.
Just going off this, giving OP benefit of the doubt. Although I didn't see any before/after measurements that are common when you lift.
I just installed these on my 2022 Bolt and it gave me a 1.5" lift to my front end.
I have my doubts as well based on both the pictures and since this is neither a higher springrate coil, preload spacer, nor coil spacer. It's something in-between that temporarily increases springrate by preventing the coils from compressing as they normally would. Theoretically it could provide some lift...

In general, even a small amount of lift to make a car/truck level should necessitate re-aiming the headlights out of common courtesy.

I guess I am just not understanding what purpose these (travel reducers?) accomplish. What is the stated improvement?
Really no purpose except to make money for a vendor. They will stop the suspension from bottoming out over harsh bumps, but at the expense that you now bottom out on these instead - so it makes the suspension feel stiffer. Better off getting actual stiffer springs or struts that still give you full suspension range.

To me, it appears that it'll prevent the springs from compressing all the way thereby providing a slight "lift". So, basically, imagine a car sitting normally with factory suspension. Now if you were to slightly lift the front end, maybe an inch, and hold it there, that's what this device OP installed does. The headlights will now point slightly higher than normal and will need adjustment.
