I'm fresh off completing the Revel Performance leveling kit on my 2020 1500 Ram and with all first time projects I learned a lot, and thankfully, not at a high cost although it took me more time than expected, which isn't really a surprise. Not sure if the pictures really show the difference but I can tell you it was significant. The kit includes the 2" Daystar spacers that mount to the top of the air strut, and the adjustable front revel links. The spacers actually measure an inch and half by the way...
Now, the biggest impact was likely moving from the 285/45/22 BFG's to the 295/55/22 Toyo Open Country AT III's. Also important as referenced above that my truck has the air suspension on it as well so I can easily adjust the front links to alter the level of the front of the truck if I want to move it up or down some.
After install, all 5 air lift settings work as they should, only slight rubbing on the passenger side inner fender which I took care of by simply pulling it back a bit. The truck doesn't ride quite as good as before, but honestly, it road like a Cadillac before and not like a truck at all, so in my opinion it stills rides nicer than any truck I've ever had. This is the first set of Toyo's I've had and for as aggressive as they look I'm amazed at how quiet they are on the road.
First and last pictures are after the leveling kit and tires, middle picture is before. Actually, I also believe the first picture is in one of the off road air suspension modes as it's pretty tall there while the last picture is in the "Normal" mode.
Not sure if this helps but thought I would pass it along in case...
