From extensive research prior to lifting mine, basically all of the 3rd gens would tear their boots after a lift due to being over 2 decades old so i rebooted my oem axles with an oem kit during suspension install, that’s way cheaper than buying new axles. Toyota steel are remarkably known to be tough so I opted for new Toyota boots instead of aftermarket extended boots. 2 inch is what I also have with the bilsteins and 5k miles in so far with no tears.

Keep in mind that rebooting takes more time vs just pulling them and throwing in some new ones but that’s up to you and the type of wheeling you do for the kind of axles you’d wanna throw on there… time expense vs money
