These are upper front suspension control arms for a Ford F150 pickup truck. These are specialty aftermarket parts made by one of the manufacturers of heavy duty off-road suspension parts for 4x4 trucks. These will fit both 4x4 and 2x4 Ford F150 trucks from 2009 to 2018. The URL I've supplied shows Tuff Country brand units that have grease fittings and a different color grease boot from yours. Yours could be an earlier version from Tuff Country or they could be made by a different company. Other than the differences I already noted they are identical in all other aspects to the ones in the URL.
