ReadyLift 3in Front / 1in Rear SST Lift Kit [69-5175]

Raises the front 3 inches and the rear 1 inch using steel strut extensions on top of the factory struts, plus a 1 inch block under the rear leaf springs. It includes the pieces most cheap kits leave out: differential drop spacers, sway bar drop spacers, skid plate spacers and the hardware.

why this one — For under four hundred dollars this gets a 2007-2021 Tundra to a proper stance and clears a 33 inch tire, and ReadyLift publishes an actual install time instead of leaving you guessing. The reason to pick this over a plain spacer level is the extra brackets - dropping the differential and the sway bar is what keeps the front end's angles close to factory after 3 inches of lift. Downside: it reuses your factory struts, so it changes height, not ride quality, and ReadyLift states it will not work on 2015-and-up TRD Pro trucks with the Bilstein or Fox TRD Pro shocks.
