ReadyLIFT offers a comprehensive 6" Lift Kit with Bilstein Shocks designed for 2007-2021 Toyota Tundra Trucks. Please note that it is not compatible with 2015-2021 Tundra TRD Pro models with Bilstein coilover shocks. This kit is specifically designed for use with factory or aftermarket 20" wheels and is not compatible with factory 18" wheels. This kit will NOT work with the TRD rear sway bar option. This 44-5677 6" lift kit offers robust laser-cut CNC-bent welded and boxed sub-frame drop assemblies. These assemblies maintain proper suspension geometry while providing over 2" more ground clearance than competitors. Precision-designed iron knuckles with CNC machining ensure a precise fit and allow for the retention of factory tie rods with minor trimming. The innovative 6" lift is achieved through an offset spacer design that attaches to the factory strut preserving the factory ride and preventing an increase in track width. This design allows you to use your stock 20" wheels and spare tire when necessary without the front tires extending further than the rear tires. The kit also includes a differential drop kit that is easy to install and correctly positions the differential to maintain optimal CV axle and driveline angles. It addresses common issues found in other Tundra lift kits ensuring that your new tires won't wear out prematurely. The system is engineered to maintain correct alignment and geometry specifications. For the rear suspension the kit features OEM-style cast iron rear lift blocks longer U-bolts with hardware bump stop extensions and sway bar frame mount brackets to maintain the front sway bar's factory position. These components contribute to an exceptional driving and handling suspension system that perfectly complements your Tundra truck. The kit also includes two (2) rear Bilstein shocks. We recommend a maximum of 35" on a 9" wheel with a +25 offset to minimize the risk of rubbing (front mud flaps may need to be removed).
