About this kit
3.5-Inch Lift Kit with N3 Shocks, fitment-checked
The N3 shock pair is what sets this 3.5-inch Tundra kit apart. Rough Country 76831RED pairs loaded front struts with a tubular upper control arm upgrade box and an N3 rear shock pair for 2007–2021 Toyota Tundra 4WD and RWD trucks. TRD Pro, Rock Warrior, and XSP-X trims are not covered. Carries a Limited Lifetime Warranty.
Three boxed assemblies make up this 3.5-inch lift kit for the 2007–2021 Toyota Tundra 4WD and RWD: a loaded strut pair up front, a 3.5-inch upper control arm upgrade box, and an N3 shock pair out back. The tubular arms hold ball joint angles in check on rubber bushings, and the loaded struts skip spring compression at assembly time. Front and rear both come up, adding ground clearance and evening out factory rake. Bolt-on work with no cutting or drilling, and a downloadable installation guide is available. Check your trim against the exclusions before ordering.
