About this kit

4-Inch Lift Kit with N3 Shocks, fitment-checked

Rough Country 40830 is a 4-inch lift kit for supported 2021–2026 Ford F-150 2WD models. The kit pairs forged aluminum knuckles and a strut/crossmember package with an N3 shock pair for the rear. Wheels must measure at least 20 inches in diameter to clear the supplied knuckle, and single-cab, two-piece-driveshaft, and CCD-equipped trucks are not covered.

This 4-inch lift kit for the 2021–2026 Ford F-150 2WD covers the XL, STX, XLT, Lariat, King Ranch, Platinum, Limited, and SSV applications listed in the fitment section. Boxed contents include a strut box, an RC crossmember box, forged aluminum knuckles, a rear kit box, and an N3 shock pair, so the front and rear come out sitting level. Plan on cutting and drilling during the install, confirm your wheel diameter, and read through the exclusions before you order. A downloadable Rough Country installation guide is available for the job.
