4-Inch Lift Kit Front Knuckles

The Rough Country 4-Inch Lift Kit is engineered to transform your 2021-2024 Ford F-150 2WD into a more capable off-road machine. It also levels the front and rear of your truck for an aggressive, confident stance. A key feature of this lift kit is its use of precision-engineered forged aluminum knuckles. These are 50% lighter than traditional steel knuckles, contributing to reduced unsprung mass, which enhances steering response and overall vehicle agility. The aluminum construction also offers superior corrosion resistance for long-lasting durability across various terrains. This kit includes durable crossmembers and all necessary hardware for a bolt-on installation process. However, it requires cutting and drilling for installation. It's important to note specific fitment exclusions: this kit does NOT fit single cab models, models with a two-piece driveshaft, or models equipped with the continuous control damping (CCD) system. Additionally, wheels must be 20 inches in diameter or larger to ensure adequate clearance with the supplied knuckles.
