About this kit
4-Inch Lift Kit with N3 Shocks, fitment-checked
Rough Country 57231 is a 4-inch lift kit for the 2009-2010 Ford F-150 2WD, built around an N3 shock pair, front struts, fabricated crossmembers, and driver and passenger knuckles. Minor drilling is part of the install. An 8-inch wide wheel is the recommended pairing; owners staying on factory wheels should keep tire width at 11.5 inches or less.
This 4-inch lift kit for the 2009-2010 Ford F-150 2WD covers FX2, STX, XL, XLT, Lariat, King Ranch, Platinum, and Harley-Davidson Edition trims listed in the fitment section. The boxed kit pairs N3 shocks with a 4-inch strut assembly, crossmembers, and matched left and right knuckles, so front ride height comes up to meet the rear without changing factory track width. Fabricated rear blocks replace cast pieces. Plan for minor drilling during the install, and review the wheel and tire limits before ordering. A downloadable Rough Country installation guide is available.
