Melling states that this line is made in the USA and uses updated oiling geometry, with the cup drilled on the side to direct oil onto the roller surface. The part number MR-1851 is listed for a wide range of Ford truck, SUV, chassis, and performance applications, including Ford F-150, Ford Mustang, and Lincoln Navigator fitments.\u003c\/p\u003e\u003cp\u003eMelling supplies rocker arms for domestic and import applications, and this Stock line reflects that OE-style replacement focus.
