I'd have preferred a 2-3" lift kit, but nobody makes one. This one is about 3.5-3.75". Some companies call them 2" kits, as they move the mounting location by 2" or so, but they all result in 3.5-4.5" of actual lift.
After doing a lot of reading online I couldn't find CV angles being an issue, even though a lot of people were asking before buying lifts. The common consensus is that the geometry looks less-than-ideal, but failures are uncommon due to the size of the joint. The kits have been around since 2016 or so. Will keep an eye on it though, as they will indeed be getting worked harder than before.
