ReadyLIFT Suspension Inc. has used proven technological engineering methods to produce a 3" SST Suspension Lift System featuring a new 1.0" Rear Block. In some cases TRD Tundra trucks have less factory rake than non-TRD models. This new tapered 1.0" rear block will give most trucks approximately a near level stance. With this kit the owner can upgrade to larger wheel and tire combinations up to 35" in diameter while retaining the great stock ride and handling characteristics. Note: Not for use on 2015 Tundra TRD Pro w/ Bilstein shocks. 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 provide 3" of front lift while retaining the OEM safe suspension geometry. No cutting or strut spring pre-loading is required for installation. Quality step-by-step instructions and all required hardware provided. Our 69-5175 SST Lift Kit will get rid of that "stink bug" stance while lifting the truck both front and rear and retaining your factory ride. Note: Our objective is to provide a product that levels the vehicle. Through research we have discovered that Toyota trucks have a unique pattern of being manufactured with varying degrees of rear to front rake. Many Toyota trucks are not the same height or possess the same rake as the same stock truck sitting next to it. Our research has determined there may be up to 1.0" difference in rake and ride height from truck to truck. TRD-equipped trucks often have less rake compared to a non-TRD truck. Measurements on some customer's trucks have revealed as much as 1.0" difference in the factory front end. Professional installation time is estimated at two to three hours. An alignment will be necessary after installation. Like all other ReadyLift kits, this lift kit is for life against manufacturing defects.
