Genuine MG-Rover knuckle joint. Racers and knowledgeable mechanics insist on this OEM component due to the heavy loading it encounters in use. Even the Unipart product is aftermarket-made these days, so only boxed MG-Rover will be to the OEM standard. If you order this part from Seven, it will be supplied in a Rover box, assuring you of a genuine product. Sold each.
