  • ReadyLIFT has had tremendous success with our leveling and SST lift kits for the 2022-UP Toyota Tundra and we are excited to announce two all-new suspension solutions:  our all-new Big 6” lift kits for trucks equipped with rear coil spring and factory air configuration.  Drawing on our Tundra first-class product success, ReadyLIFT Tundra 6” lift kits incorporate our all-new Falcon 1.1 monotube shocks specifically designed, engineered, and tuned for 2022+ Toyota Tundra Trucks!

     

    The all-new 6” lift kits 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 maintain suspension geometry and increase available ground clearance! Our proprietary, precision-designed cast iron front knuckles feature CNC-machining to ensure fit while retaining the factory tie rods with minimal trimming required.

     

    The ReadyLIFT sub-assembly design features a truly innovative approach to dropping the differential. The differential drop system is engineered for easy installation.  The sub-assembly correctly positions the differential to maintain CV axle and driveline angles. With 44-52620 (non-rear air) & 44-52660 (with rear air) lift kits, you can rest assured premature tire wear won’t be an issue. The ReadyLIFT system is built around maintaining proper alignment and geometry specifications. 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 elevates the typical Toyota Tundra truck!

    ·      -  Allows for 5.75" backspace (18-20mm Offset) on 20x9 with 35" tires

    ·      -  Max tire with trimming 5.5" backspace (10-13mm Offset) on 20x9 with 37" tires

    ·      -  Includes two Falcon 1.1 monotube rear shocks

    ··   -  Retains factory turning radius

    ·      -  Allows for use of stock 20” wheels

     

    NOTE: Not for use on 2022+ Tundra TRD Pro w/ Bilstein coilover shocks, the TRD rear sway bar option.  Kits only work with factory 20" wheels - will not work with factory 18" wheels. Most aftermarket wheels are compatible (confirm fitment prior to installation). Toyota OEM lift kit cv shafts PT362-3432B and PT362-3431B are recommended by Toyota on all lifted 22-UP Tundra's. Failure to use these axle shafts may lead to damage if used in 4WD not covered by the manufacturer.

    Max tire with trimming 5.5" backspace (10-13mm Offset) on 20x9 with 37" tires

    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.
