About this kit
6-Inch Lift Kit with M1 Shocks, fitment-checked
Rough Country 71240 is a 6-inch lift kit for compatible 2022–2026 Toyota Tundra 4WD models, built around an M1 loaded strut pair up front and an M1 monotube shock pair with rear coils out back. Cutting and drilling are part of the job, and 20-inch or larger aftermarket wheels are required. It does not fit TRD Pro models with the 1.1-inch factory lift, trucks with Adaptive Variable Suspension, or trucks with the factory rear load-leveling air suspension.
This 6-inch lift kit for the 2022–2026 Toyota Tundra 4WD ships as a boxed package: knuckles, the main kit hardware, a high-clearance crossmember, skid plates, rear coils, and the M1 strut and shock pairs. Rear upper control arm relocation brackets are included for added droop clearance, and factory track width and alignment specs are retained. Clearance allows up to 35-inch tires, with 37-inch tires possible after minor trimming depending on wheel offset. Toyota Safety Sense may need recalibration afterward. A downloadable installation guide is available before you start.
