About this kit
6-Inch Lift Kit with N3 Shocks, fitment-checked
Rough Country 75431 is a 6-inch lift kit for 2007-2015 Toyota Tundra 4WD, built around a high-clearance crossmember, loaded front struts, fabricated rear blocks, and an N3 shock pair. It does not fit Pro Series, Rock Warrior, or XSP-X models. Minor cutting and drilling is part of the job, and 18-inch or larger wheels are required.
This 6-inch lift kit for the 2007-2015 Toyota Tundra 4WD covers Base, SR, SR5, Limited, Platinum, and 1794 Edition trims listed in the fitment section. The box holds the 6-inch kit and crossmember cartons, a knuckle kit, an N3 shock pair, and a loaded strut pair, so front lift comes from the struts themselves rather than spacers. Factory 18-inch or larger wheels can stay, though they take tires no wider than 11.5 inches, and clearing 35-inch tires can call for light trimming. Two-piece-driveshaft trucks may see take-off vibration; a carrier bearing shim kit addresses it. Review the downloadable installation guide before starting.
