Rough Country F-150 Tremor 4in Lift Kit w/ N3 Shocks (2021-2026)

Rough Country's 4-inch lift kit gives the F-150 Tremor the additional ground clearance and leveled stance its off-road character demands. Forged aluminum knuckles and strut spacers work together to raise the front of the truck to match the rear, creating a balanced platform ready for up to 35-inch tires with proper wheel spacing. The kit retains factory track width, so the geometry stays predictable both on the trail and on the highway.

Forged aluminum knuckles set this kit apart. At 50% lighter than comparable steel knuckles, the forged aluminum construction reduces unsprung mass across the front axle, which translates to quicker steering response, improved handling, and a marginal benefit to fuel economy. The same forging process that reduces weight also matches OEM strength expectations, so the knuckles handle both daily driving loads and harder off-road use without compromise.

Heavy-gauge steel structure throughout. A quarter-inch plate steel front cross member and a matching rear cross member tie the kit together with structural rigidity the stock suspension geometry relies on. Fabricated rear lift blocks replace cast designs, delivering a longer service life and more consistent load distribution across the rear axle.

Straight bolt-on assembly with N3 shocks included. Every component in the kit installs using standard hand tools with no cutting, welding, or modifications to OEM hardware. Rough Country estimates the full installation at 8 to 10 hours, making it a realistic home garage project for an experienced DIY installer. N3 shocks are included to restore proper damping at the new ride height.
