ReadyLIFT 8 Inch Front 6-7.5 Inch Rear Lift Kit - 2007-2021 Toyota Tundra (44-5877)

This ReadyLIFT kit gives the 2007-2021 Toyota Tundra 2WD and 4WD an 8 inch lift in front and a 6 to 7.5 inch lift in the rear, and it includes two Bilstein rear shocks. Like the 6 inch Tundra kit, the front lift comes from an offset spacer design that does not increase track width, plus boxed steel subframe drops and CNC-machined iron knuckles that let you keep the factory tie rods. It allows up to 37 inch tall tires and is made in the USA. Front shocks are not included.
