6" MAX3.3 Suspension System - 2022-2025 Toyota Tundra W/ Rear Coil Springs 2WD/4WD

Toyota’s latest-generation Tundra is redefining the full-size truck market, and ReadyLIFT is taking it to the next level with the all-new 6” MAX3.3 Lift Kit (PN: 42-52640)—delivering superior ground clearance, aggressive styling, and next-level performance for both on-road and off-road adventures.

At the heart of this new kit are the game-changing Falcon 3.3 Fast Adjust Dampers, offering on-the-fly adjustability with 8-position micro tuning and a 3-position Fast Adjust Knob—allowing you to dial in your ride for maximum comfort or firm, responsive handling. Whether you’re cruising to work, towing heavy loads, or conquering rugged terrain, these premium dampers ensure unmatched versatility and control in every scenario.

But we didn’t stop there—this kit also introduces ReadyLIFT’s all-new High-Angle CV Axle Upgrade, engineered to withstand extreme 4WD conditions with superior durability and enhanced articulation. Say goodbye to vibration and premature wear—these heavy-duty axles keep your Tundra performing at its peak, no matter the challenge.

6” MAX3.3 – Premium Features & Benefits:

·         Falcon 3.3 Fast Adjust Dampers – Instantly switch between Soft, Custom, or Firm settings with precision tuning for any terrain.

·         High-Angle CV Axles – Designed for extreme durability with enhanced articulation, stronger shafts, and a true CV joint for smoother operation at lifted heights.

·         Massive Tire Fitment – Run 35” tires with 20”x9” wheels (18-20mm offset) for an aggressive stance and off-road capability.

·         Heavy-Duty Shock Body & Components – 6061-T6 Aluminum construction, Red Line high VI shock oil, and volume-optimized damping (VOD) to handle extreme conditions.

·         Retains Factory Ride & Turning Radius – Experience the best of both worlds: a lifted, aggressive truck without sacrificing ride quality or maneuverability.

Designed specifically for 2022+ Toyota Tundra models, including those equipped with the i-FORCE MAX hybrid powertrain, this kit is engineered to handle whatever the road—or trail—throws at you.

NOTE: Not compatible with Tundra TRD Pro w/ Bilstein coilovers or TRD rear sway bar. Designed for factory 20” wheels—most aftermarket 20”+ wheels are compatible (verify fitment before installation).

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

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.
