ReadyLIFT Suspension offers a 3" SST Suspension Lift System (P/N 69-5276) designed for 2007-2021 Toyota Tundra / TRD / SR5 / Rock Warrior trucks with a 2.0" Rear Block. This innovative Smart Suspension Technology system is compatible with all 2007-2020 Toyota Tundras, including 2WD and 4WD models, catering especially to TRD models. Some TRD Tundra trucks may have less factory rake than non-TRD models, making a 1-inch rear block insufficient to level the rear after installing the 3.0" front strut extension. However, the included tapered 2.0" rear block in the 69-5276 kit addresses this issue by providing approximately a one-half inch rear rake for most TRD / SR5 / Rock Warrior trucks. The complete suspension lift kit includes a powder-coated steel strut extension, front differential drop spacers, sway bar spacers, skid plate spacers, and a 2" rear lift block. It offers a 3" front suspension lift while maintaining OEM-safe suspension geometry, without requiring cutting or strut spring pre-loading. Detailed instructions are included with every kit. This lift kit not only levels the vehicle but also allows for larger wheel and tire combinations up to 33" in diameter while preserving the factory ride quality that Toyota owners cherish. Please note that this kit is not suitable for use on 2015-21 Tundra TRD Pro models with Bilstein or Fox TRD Pro shocks. ReadyLIFT's research shows that Toyota trucks vary in rear-to-front rake, with differences of up to 1.0" in ride height between trucks. TRD-equipped trucks tend to have less rake than non-TRD trucks. Therefore, the objective of ReadyLIFT's product is to level the vehicle, accounting for these variations in Toyota truck manufacturing and sales. This lift system effectively eliminates the "stink bug" stance while maintaining the exceptional ride and handling expected from Toyota pickups.
