Product Description
Genuine Johnson SET-38 X2 Main Bearing Set (.002 in Undersize)
Restore the precision of your classic Nash or Rambler engine with this genuine Johnson SET-38 X2 Main Bearing Set. This is a vintage New Old Stock (NOS) component, preserved in its original packaging. Unlike standard bearings, the "X2" designation indicates a .002-inch undersize (often referred to as .002 under), specifically designed for crankshafts that have been micro-polished or ground to address minor wear while maintaining tight oil clearances. This set is engineered for the Nash/AMC 6-cylinder engines (172.6, 184, and 195.6 cubic inches) used in various Nash 600, Statesman, and Rambler American models from 1941 through 1965.

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 and cross-reference our fitment data using vintage manufacturer catalogs. While we strive for 100% accuracy, these decades-old resources—and the humans reading them—can occasionally contain errors. Additionally, these parts may fit other vehicles and years not explicitly listed in our data. To ensure a seamless restoration, we kindly ask that you perform your own due diligence and verify that this specific part number is correct for your application prior to purchase.
Unbeatable Prices & Expectations

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.
