Product Description
Genuine Ford 52-6333-D Crankshaft Main Bearing (NOS)
Keep your vintage build entirely authentic with this pair of genuine New Old Stock (NOS) Ford Motor Company crankshaft main bearings (includes 2 half-shells). Made in Dearborn, Michigan, these original front/center main inserts feature the factory center oil groove and oil feed holes. This set is designed exclusively for the 1937, 1938, and 1939 Ford Flathead V8-60 (60 HP) small-block engine family. It interchanges directly with Federal-Mogul part number 9541SB-020. It will not fit the larger 85 HP / 95 HP / 100 HP (221 or 239 cubic inch) Flathead V8 engines. This is a highly collectible, original Ford box—perfect for an authentic period-correct traditional hot rod restoration, vintage midget racer, or sprint car engine build.

Note on Stock Photos: Due to our inventory of multiple identical units for this specific part number, we utilize representative stock photos for this listing. You will receive a component that strictly meets all listed specifications and fitment requirements. Please be aware that because these are vintage parts, minor cosmetic variations—such as surface finish, color, or production markings—may exist between different manufacturing runs. These slight aesthetic differences are a result of historical production processes and do not impact the part's integrity, performance, or authenticity.
A Note on Fitment Accuracy: We manually research our fitment data using vintage manufacturer catalogs to provide you with the most accurate information possible. However, because we are human and these decades-old resources can occasionally contain errors, we cannot guarantee 100% accuracy. We strongly encourage you to perform your own due diligence and verify this part number for your specific application before purchasing. Please note that this part may also fit other vehicles or years not explicitly listed in our research.
Unbeatable Prices & Expectations
While many of our vintage parts were manufactured decades ago, they remain unused and high-quality. Some original boxes may show signs of shelf-wear, such as dust, tape, or surface distress from years of storage. Rest assured, the components inside have been inspected to ensure they are complete and ready to help you finish your project without breaking the bank.
