  • The venerable ReadyLIFT 8” kit for 2007-2021 Toyota Tundra has been a favorite big lift solution for Tundra owners.  Drawing on this product success, ReadyLIFT proudly introduces an updated version now available with our all-new Falcon 1.1 monotube rear shocks specifically designed, engineered, and tuned for 2007-2021 Toyota Tundra Trucks!

     

    The 44-58770 8" lift kit for Tundra trucks are packed with great standard features! Starting with our ultra-strong laser cut, CNC bent, welded and boxed sub-frame drop assemblies that keep the suspension geometry where it is supposed to be and increases available ground clearance! Our proprietary, precision-designed iron front knuckles feature CNC-machining to guarantee fit while retaining the factory tie rods with minor trimming required.

     

    The new ReadyLIFT Tundra front lift is achieved using the time-tested offset spacer design. These strong steel spacers attach to the factory strut - resulting in a factory ride - while positioning the suspension in such a way as to not increase track width. What does that mean? It means the front tires won't still out further than the rear tires like most other kits. It means owners can run stock 20" wheels and use the factory spare tire if needed (restrictions apply).

     

    The ReadyLIFT sub-assembly design features a truly innovative approach to dropping the differential. The differential drop system is engineered for easy installation and correctly positions the differential to maintain CV axle and driveline angles. With the 44-58770 lift kit customers can rest assured they will not be prematurely wearing out tires. The ReadyLIFT system is built around maintaining proper alignment and geometry specifications. For the rear, this kit includes the time-tested OEM-style cast iron rear lift blocks and longer U-bolts with hardware. Additionally, ReadyLIFT also includes thoughtful accessories such as new bump stop extensions all the way around as well as sway bar frame mount brackets to keep the front sway bar in a factory geometry. All of this contributes to an excellent driving and handling suspension system that truly enhances the typical Toyota Tundra truck.

    • 37" Maximum tire diameter

      37x12.50 for no rub on a 9" wide wheel with +25 offset

      Tire Size Note: ReadyLIFT wheel and tire fitment recommendations are typically based on Wheel Pros wheels and Nitto tires. Due to product differences among tire manufacturers, tire specifications and dimensions including, but limited to, overall diameter, rolling diameter, tread width, aspect ratio, lug pattern, sidewall construction and inflation pressure, will vary meaningfully by tire and wheel manufacturer. Every tire and wheel combination should be test fit prior to installation. Consult your local installer to learn more about the right tire fitment for your application.

      Ride Quality Note: When lifting a vehicle and installing aftermarket wheels and tires, a tire manufacturer's construction and material quality can alter vehicle ride quality. When increasing a vehicle wheel and tire size, most larger aftermarket truck and SUV tires are 10-ply (or more) E tires compared to typical OEM 6-ply C tires. This more rigid sidewall construction increases the perception of suspension stiffness often described as ride harshness. The ride, handling, traction, noise, fuel economy, and wear differences between All-Season, All-Terrain, Mud-Terrain, or Trail-Terrain type tires can be significant. Please take into account tire and wheel choice will generally have a meaningful impact on the ride & handling experience.
