If your 2022+ Tundra is a 4WD and you are adding one of the Cognito 3" leveling kits, it is recommended to add this differential drop kit if you will be using 4WD for anything more than very light use. The OEM front CV axles in the Toyota Tundra are a simple tri-pod style and not very robust unless you have the Pro or TRD Offroad package that has the silver or red axles. If you are thoroughly using 4WD, it is recommended to add this differential drop kit as well as upgrade your axles to the red or silver axles.
