ReadyLIFT offers an impressive 8" lift kit designed specifically for 2007-2021 Toyota Tundra trucks providing a substantial increase in ground clearance compared to competitors. Please note that this kit is not suitable for use on 2015-2021 Tundra TRD Pro models with Bilstein coilover shocks and is compatible only with factory 20" wheels not 18" wheels (aftermarket wheels are acceptable). It is not compatible with the TRD rear sway bar option. The 44-5875 8" lift kit boasts a range of outstanding features including laser-cut CNC-bent welded and boxed sub-frame drop assemblies that maintain suspension geometry while elevating ground clearance by 2". Precision-designed iron knuckles with CNC machining ensure a precise fit while retaining factory tie rods (minor trimming may be required). The lift is achieved through an innovative offset spacer design that allows you to maintain a factory ride without increasing track width ensuring that your front tires won't protrude further than the rear tires. The sub-assembly design includes an innovative differential drop kit that is easy to install and correctly positions the differential to maintain optimal CV axle and drive line angles. This kit is engineered to address common issues found in other Tundra lift kits prioritizing correct alignment and geometry specifications to prevent premature tire wear. In the rear the kit includes OEM-style cast iron rear lift blocks longer U-bolts with hardware bump stop extensions and sway bar frame mount brackets to retain the front sway bar's factory position. These components work together to create a well-balanced and responsive suspension system that complements your Tundra truck. Regarding tire size we recommend a maximum of 37" tires on a 9" wheel with a +25 offset for minimal risk of rubbing (note that front mud flaps may need to be removed). Please be aware that shocks are not included with this kit so new shocks will be required for installation.
