Give your 2007-2021 Toyota Tundra a taller stance with the ReadyLIFT 8-Inch Lift Kit, part number 44-5877. Designed for 2WD and 4WD trucks, the system includes two Bilstein rear shocks and accommodates up to 37-inch tires with the specified wheels.

Steel strut spacers, laser-cut and CNC-bent boxed subframe assemblies, machined iron steering knuckles, and differential drop components address suspension and driveline geometry. The spacer design retains the factory struts without increasing track width.

OEM-style cast iron rear blocks, longer U-bolts, bump stop extensions, sway bar frame brackets, and hardware complete the system. The kit retains the factory turning radius and is made in the USA.

Fitment and Installation Notes

• Not compatible with the TRD rear sway bar option.
• Factory wheel compatibility is limited to 20-inch wheels. Factory 18-inch wheels and 17-inch aftermarket wheels are not compatible. Confirm aftermarket wheel fitment before installation.
• Recommended maximum tire: 37 inches on a 9-inch-wide wheel with a +25mm offset. Front mud flaps may need removal.
• Minor trimming is required to retain the factory tie rods.

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.
