About this kit
6-Inch Lift Kit with M1 Shocks, fitment-checked
Rough Country 75440 is a 6-inch lift kit for compatible 2007-2015 Toyota Tundra 4WD models, built around an M1 monotube loaded strut pair and an M1 monotube shock pair. Wheels must measure 18 inches or larger, and factory 18-inch wheels can carry tires up to 11.5 inches wide. It does not fit Pro Series, Rock Warrior, or XSP-X trims.
This 6-inch lift kit for the 2007-2015 Toyota Tundra 4WD covers SR, SR5, Limited, Platinum, 1794 Edition, and Base submodels listed in the fitment section. The boxed kit ships with a knuckle kit, a high-clearance crossmember box, fabricated rear blocks, and the M1 monotube strut and shock pairs, so no strut spacers are needed up front. Minor cutting and drilling is part of the job, and clearing 35-inch tires can call for light trimming. Trucks with a two-piece driveshaft may show take-off vibration, addressed with carrier bearing shim kit 1776BOX1. A downloadable installation guide is available.
