Wellll.. what do you mean by "okay"? My cv's, like many others on here, are at a pretty significant angle over stock. They will break easier with this lift than without. Depending on your driving style offroad and/or difficultly of trail, front locker or not, you'll either not have many issues or you might break one quite often. Lots of people on here say 3" lift with a diff drop to make it a 2" impact is not a big deal on cv's but go past that and you'll prob get the dreaded snap noise from time to time. However it is not that expensive to fix. Worth it to me for the extra lift. :driving:
Just so ya know: after reading tons of Q&A's while doing research on here and yotatech, steezemcqueen, brian2sun and Baja Runner know more about the 4runner than Toyota does and could probably answer any ? you could possibly think of. Good luck!
