ReadyLift 4"F / 2"R SST Lift Kit

 

The ReadyLIFT 4"F / 2"R SST Lift Kit is engineered specifically for 2007–2021 Toyota Tundra 2WD and 4WD trucks that require increased ride height, larger tire clearance, and improved off-road capability while maintaining factory ride comfort and drivability. Built around ReadyLIFT Smart Suspension Technology, this system combines heavy-duty suspension components with geometry correction hardware to deliver balanced on-road comfort and off-road performance.

Built around ReadyLIFT’s heavy-duty SST suspension architecture, the system features DOM steel tubular upper control arms equipped with extended-duty ball joints and TCT free-floating pivot bushings engineered to maintain OEM ball joint angles and improve suspension articulation. These control arms are specifically designed to provide proper strut and coilover clearance during suspension droop cycling while reducing friction and improving long-term durability.

Additional features include powder-coated steel front strut extensions, differential drop spacers, skid plate spacers, sway bar frame mount spacers, brake line extension brackets, front bump stop extensions, rear shock extensions, and OEM-style cast rear lift blocks. ReadyLIFT engineered the SST system to provide a complete suspension solution that maintains OEM alignment specifications without requiring cutting, welding, or strut preloading.

The SST system provides approximately 4 inches of front lift and 2 inches of rear lift, creating an aggressive leveled stance while preserving proper suspension geometry and driveline alignment. ReadyLIFT states the system supports up to 34-inch tires depending on wheel width, wheel offset, and tire design. Confirmed fitments include 34x11.50 tires on 9-inch-wide wheels with +25 offset.

Engineered specifically for Toyota Tundra applications, the ReadyLIFT 4"F / 2"R SST Lift Kit delivers improved suspension capability, enhanced ride quality, and aggressive styling while maintaining OEM-style comfort and drivability.

Installation is designed as a complete bolt-on suspension system using application-specific hardware and geometry correction components. ReadyLIFT states the system requires no cutting of OEM parts or welding and fully retains OEM alignment geometry.

Whether you're upgrading for larger tires, overlanding, trail use, towing capability, or a more aggressive truck stance, the ReadyLIFT 4"F / 2"R SST Lift Kit delivers premium suspension enhancement for Toyota Tundra trucks. Now Available at LEER!
