ReadyLIFT has utilized advanced technological engineering methods to create a 3" SST Suspension Lift System (P/N 69-5175) tailored for 2007-2021 Toyota Tundra including TRD SR5 and Rock Warrior models with a 1.0" Rear Block. This innovative 3" intermediate Smart Suspension Technology system is compatible with all 2007-2019 Toyota Tundras encompassing Crew Max Double Cab and Standard Cab variants both 2WD and 4WD with a specific focus on TRD models. In some instances TRD Tundra trucks exhibit less factory rake than their non-TRD counterparts. The new 1.0" rear block included in the 69-5175 kit addresses this resulting in a nearly level stance for most TRD SR5 and Rock Warrior trucks. This kit comes with a powder-coated steel strut extension front differential drop spacers sway bar spacers skid plate spacers and a new 1" rear lift block. Notably the SST strut extension and diff drop bracket deliver a 3" front suspension lift while preserving OEM suspension geometry for safety. This system stands out by requiring no cutting or strut spring pre-loading during installation ensuring a quick and secure setup with the provided heavy-duty hardware. Detailed step-by-step instructions are included with each kit. The 69-5175 SST Lift Kit for Toyota Tundra TRD SR5 and Rock Warrior models effectively eliminates the "stink bug" stance elevating both the front and rear of the truck while maintaining the factory ride quality. ReadyLIFT prioritizes delivering a product that levels the vehicle acknowledging that Toyota trucks exhibit varying degrees of rear-to-front rake due to manufacturing and sales variations. This system accommodates these differences with TRD-equipped trucks often having less rake compared to non-TRD models with potential variations of up to 1.0" in front-end height observed among different trucks. Please note that this kit is not suitable for use on 2015-2021 Tundra TRD Pro models equipped with Bilstein or Fox TRD Pro shocks.
