6 Inch Lift Kit, fitment-checked
A 6 inch lift kit for the previous-generation 2015-2020 Ford F-150 4WD (Rough Country 55750). Regular and standard cab trucks are excluded — the pinion angle causes drivetrain vibration at this height.
This kit fits the 2015-2020 Ford F-150 4WD from XL through Limited. It does not fit regular or standard cab trucks: at 6 inches of lift their pinion angle causes drivetrain vibrations, so Rough Country excludes them outright. If you're keeping the factory wheels, stay at or under an 11.5-inch-wide tire. Cutting and drilling are part of the install, and a step-by-step guide is included. Shipping weight is 287.7 lb — freight delivery.
