About this kit
6-Inch Lift Kit, fitment-checked
Rough Country 75900_A is a 6-inch lift kit for supported 2022–2025 Toyota Tundra models in 4WD and RWD, covering SR, SR5, Limited, Platinum, 1794 Edition, and Capstone. Shocks and struts are chosen separately, so you can pair it with N3 or Vertex units. Aftermarket wheels of 20 inches or larger are required, and cutting and drilling is part of the job.
This 6-inch lift kit for the 2022–2025 Toyota Tundra 4WD and RWD ships as five boxed sub-assemblies: knuckles, a high-clearance crossmember, strut spacers, a rear shock bracket with rear upper control-arm relocation brackets for added droop clearance, and skid plates. Factory track width and alignment specs are retained. It clears 35-inch tires, and 37-inch tires with light trimming depending on wheel offset. It will not work on TRD Pro models, which carry a 1.1 in factory lift, or on trucks with Adaptive Variable Suspension, the OE rear load-leveling air system, or XSP-X trim. Toyota Safety Sense may need recalibration afterward.
