About this kit
4-Inch Lift Kit with N3 Shocks, fitment-checked
Rough Country 70430 is a 4-inch lift kit for compatible 2022–2026 Toyota Tundra models in 4WD and RWD. The kit pairs lifted knuckles, strut spacers, and front and rear crossmembers with an N3 shock pair, and calls for 20-inch or larger wheels. It does not fit TRD Pro Series, XSP-X, or trucks with the rear air ride system.
This 4-inch lift kit for the 2022–2026 Toyota Tundra covers SR, SR5, Limited, Platinum, 1794 Edition, and Capstone applications listed in the fitment section, in both 4WD and RWD. A high-clearance crossmember design carries the front end while factory track width and alignment specs are retained, and rear upper control arm relocation brackets handle droop clearance. Cutting and drilling are part of the job, and Toyota Safety Sense may need recalibration afterward. Rough Country lists an install time of 8-10 hours. Check the exclusion list and the 20-inch wheel minimum, then work from the downloadable installation guide.
