About this kit

6-Inch Lift Kit with M1 Shocks, fitment-checked

Rough Country 59840 is a 6-inch lift kit for 2009–2010 Ford F-150 4WD and AWD models, built around an M1 loaded strut pair up front and an M1 monotube shock pair at the rear. It clears tires up to 35 inches and keeps the factory track width. Minor cutting and drilling is required, and it does not fit Raptor or seven-lug Heavy Duty Payload Package trucks.

This 6-inch lift kit for the 2009–2010 Ford F-150 4WD arrives as a boxed kit with M1 loaded struts, an M1 monotube shock pair, driver and passenger knuckles, a crossmember, rear lift components, and universal hardware. The front lift brings the nose up level with the rear while retaining factory track width, and the rear blocks are shaped to resist axle wrap so ride quality stays close to stock. Clearance is sized for tires up to 35 inches. Plan on minor cutting and drilling during the install, and check the exclusions before you order.
