About this kit
6-Inch Lift Kit, fitment-checked
Rough Country 75900 is a 6-inch lift kit for compatible 2022–2025 Toyota Tundra models in 4WD and RWD. The box holds knuckles, a high-clearance crossmember, strut spacers, rear upper control arm relocation brackets with shock bracket, and skid plates. It does not fit TRD Pro models with the 1.1-inch factory lift, XSP-X models, or trucks with Adaptive Variable Suspension or the factory rear load-leveling air suspension. Aftermarket wheels of 20 inches or larger are required.
This 6-inch lift kit for the 2022–2025 Toyota Tundra 4WD and RWD raises the front to match the rear and takes out the factory rake, while the crossmember and knuckle design keeps track width and alignment specs close to stock. Laser-cut components and CAD-developed geometry set the fit. It clears 35-inch tires as supplied and 37-inch tires with minor trimming, depending on offset and tire choice. Cutting and drilling are part of the job, and Toyota Safety Sense may need recalibration afterward. Shock and strut choices, from N3 to Vertex reservoir units, are configured separately. A downloadable installation guide is available.
