With the addition of a lift kit on your Ford F150, replacing the factory control arms with the Rough Country upper control arms makes sense. These arms are forged aluminum to create a one piece design to provide the additional strength and durability you're looking for. This design will out-perform all other types of construction. There are no welding weak spots to potentially bend or break.The POM ball joints offer more wheel articulation than OE or standard arms. The Polyoxymethylene ball race features an extremely low coefficient of friction for longer life. The larger ball diameter also improves range of motion and is maintenance free. Each ball joint is fully greaseable.FeaturesMade of forged aluminum for unsurpassed strength and durabilityNo welding weak spotsCorrected ball joint angle for lifted applicationsIncludes POM ball joints for greater range of motion and easier installationsBall joints are fully greaseableIncludes Clevite brand OEM style rubber bushingsView installation instructions</strong
