This is a set of oversized main bearings for a 2.1l waterboxer Vanagon engine. If the case has been bored over it is usually done to the .50mm or .020" size. The only bearings that are currently available for a bored case are the ones that also require you to have your crank turned .25mm (.010"). The thrust surface is standard. All VW factory rebuilt engines that have the yellow factory rebuild sticker on them were bored over .50mm on the case. That yellow sticker is found on the driver's side (left) of the engine block on the top under the intake runners.
