ReadyLIFT has used proven technological engineering methods to produce a 3″ SST Suspension Lift System (P/N 69-5175) for the 2007-2021 Toyota Tundra / TRD / SR5 / Rock Warrior trucks featuring a 1.0″ Rear Block. The 3″ intermediate Smart Suspension Technology system fits all 2007-2019 Toyota Tundras / TRD / SR5 / Rock Warrior (Crew Max, Double Cab, Standard Cab), including both 2WD and 4WD models, particularly the TRD model trucks. In some cases TRD Tundra trucks have less factory rake than non-TRD models. This new 1.0″ rear block included in the 69-5175 kit will give most TRD / SR5 / Rock Warrior trucks approximately a near level stance. This kit provides the owner with the opportunity to upgrade to larger wheel and tire combinations up to 35″ in diameter while retaining the great stock ride and handling characteristics. This is a complete suspension lift kit that includes a powder coated steel strut extension, front differential drop spacers, sway bar spacers, skid plate spacers, and new 1″ rear lift block. The SST strut extension and diff drop bracket have been designed to provide 3″ of front suspension lift while retaining the OEM safe suspension geometry. Unlike other kits, the ReadyLIFT 3″ suspension system requires no cutting or strut spring pre-loading and installs quickly and safely using the provided heavy-duty hardware. Quality step-by-step instructions are provided with every kit. Our 69-5175 SST Lift Kit for the Toyota Tundra TRD / SR5 / Rock Warrior will get rid of that “stink bug” stance while lifting the truck both front and rear and retaining your factory ride. Toyota pickups are built around quality and ReadyLIFT has designed this 3″ / 1″ lift system to retain the quality ride and handling that you expect from a Toyota.
