This is a new rear wheel hub for 2WD Vanagons, 4WD Vanagons, and '71-'79 T2 Buses. Hubs come with OEM length studs installed. To fit most rear disc brake conversion kits you'll need longer studs. Please add those on the drop down if you need them. If you would like your hubs machined down to fit rear disc brake conversion kits please choose that option from the drop down. Machining hubs will add up to 1 week to your delivery time.
