ReadyLIFT venerable 4  SST Lift Kit is now available with all-new Falcon 1.1 Monotube rear shocks making it the smoothest lift kit for the 2007-2021 Toyota Tundra in the market.   Offering easy installation and an aggressive look at an incredible value. This kit is packed with great features starting with our DOM steel tube Upper Control Arms equipped with heavy-duty ball joints and tough TCT polymer bushings. These control arms are designed to retain optimal ball joint angles while also providing necessary strut/coil-over clearance during suspension droop cycling.   Also included are the Falcon 1.1 Monotube rear shocks that complement the eye-catching 4" of lift while delivering superior ride and handling performance. Differential drop spacers and skid plate spacers with new hardware, front bump stop extensions, OEM-style rear lift blocks, and U-bolts are included to bring the rear of Tundra up for a level-but-lifted stance.    Once installed, this kit gives your truck plenty of clearance for larger tires. This kit contains everything for a smooth lifted conversion - no details were skipped with this kit! We include new front sway bar frame mount spacers as well as brake line bracket extensions to deliver a truly exceptional ownership experience.   This SST Kit is easy to install with zero permanent vehicle modifications and is fully capable of retaining OEM alignment geometry specifications.   Unlike many other competitor kits, this ReadyLIFT 4" SST suspension system requires no cutting or strut spring pre-loading and installs securely using the provided heavy-duty hardware.   Quality step-by-step instructions are provided with every kit.
