ReadyLIFT has had tremendous success with ReadyLIFT's leveling and SST lift kits for the 2022-UP Toyota Tundra and we are excited to announce two all-new suspension solutions: ReadyLIFT's all-new 6" lift kits for trucks equipped with rear coil spring and factory air configuration. Drawing on ReadyLIFT's Tundra first-class product success, ReadyLIFT Tundra 6" lift kits incorporate ReadyLIFT's 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 ReadyLIFT's ultra-strong laser cut, CNC bent, welded, and boxed sub-frame drop assemblies that maintain suspension geometry and increase available ground clearance! ReadyLIFT's 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!

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.

Please read Instructions thoroughly and completely before beginning installation. Installation by a certified mechanic is recommended.

Estimated Installation Time: 16 Hours +/- 1 hour (excluding alignment and wheel/tire assembly)
