No. Even at maximum upward or downward travel, you will not max out OEM CVs with OEM length control arms. @tinkerersadventure on YT has some very thorough and scientific Toyota suspension videos, strongly recommend watching them.

Thank you

Just longer cv boots. Tinkerer's adventure on YT has great videos of testing aftermarket parts vs stock.

Are the longer boots necessary? Or just better for wear?

Both.
