About this kit

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.
