Product Overview
The ReadyLIFT 4" Lift Kit is engineered specifically for 2015–2021 Toyota Tundra TRD Pro 2WD and 4WD trucks seeking increased ride height, larger tire clearance, and enhanced off-road capability while retaining factory TRD Pro suspension performance. Designed as the TRD Pro Plus 4 Lift Kit System, this premium suspension package allows owners to maintain the factory Bilstein or Fox TRD Pro shocks while achieving lift height comparable to ReadyLIFT’s standard 6-inch Tundra systems.
Built around ReadyLIFT’s heavy-duty suspension architecture, the system includes laser-cut, CNC-bent, welded, and boxed subframe drop assemblies engineered to preserve proper suspension geometry and improve ground clearance. ReadyLIFT states the design increases ground clearance by approximately 2 inches compared to many competing drop-bracket systems while maintaining excellent ride quality and steering characteristics.
The kit also features precision CNC-machined iron steering knuckles designed specifically for the Toyota Tundra TRD Pro platform. These heavy-duty knuckles retain compatibility with factory tie rods while preserving OEM steering geometry and handling characteristics after lifting. Additional suspension correction components include differential drop hardware, sway bar extensions, skid plate spacers, and rear lift blocks engineered specifically for TRD Pro applications.
One of the system’s most important advantages is its ability to retain all factory TRD Pro suspension components, including the Bilstein or Fox front coilovers and rear reservoir shocks. ReadyLIFT engineered the system specifically around the TRD Pro suspension package to maintain factory ride comfort, damping performance, and off-road capability while dramatically increasing tire clearance and ride height.
The ReadyLIFT 4" Lift Kit supports up to 35x12.50-inch tires while retaining the factory turning radius on compatible wheel setups. The system is designed to work with factory 20-inch TRD Pro wheels, although ReadyLIFT notes the system is not compatible with certain factory 18-inch wheel configurations.
Engineered specifically for Toyota Tundra TRD Pro trucks, the ReadyLIFT 4" Lift Kit delivers improved off-road capability, aggressive styling, enhanced tire clearance, and factory-quality suspension performance without sacrificing drivability.
Installation is designed as a complete bolt-on suspension system using application-specific hardware and geometry correction components. ReadyLIFT estimates installation time at approximately 6–10 hours depending on vehicle condition and installer experience.
Whether you're upgrading for larger tires, overlanding, trail performance, or a more aggressive TRD Pro stance, the ReadyLIFT 4" Lift Kit delivers premium suspension enhancement for Toyota Tundra TRD Pro trucks. Now Available at LEER!
