Product Description
Genuine EBS-242 B Main Bearing Set (.020 Undersize) (NOS)
This is a genuine New Old Stock (NOS) main bearing set, part number EBS-242 B. Precision-manufactured in the USA, this vintage engine component set is finished to .020 undersize, specifically for crankshafts that have been reground to .020" below standard specifications. The original packaging features handwritten notations suggesting a possible application for **1948-1953 Chevrolet and GMC** engines. However, because we have been unable to independently verify this specific EBS part number in period-correct technical catalogs, we are presenting this fitment as **unconfirmed**. This kit is intended for engine builders and restorers who can independently validate that this specific part number and dimensions are correct for their unique project.
Please Note: Because our physical catalogs do not currently contain the specific application data for this vintage part number, we are unable to provide technical fitment advice or confirm if it will fit your vehicle. We kindly ask that you do not contact us regarding fitment inquiries for this item, as we do not have additional information beyond what is presented in the listing. This part is offered strictly for those who have independently verified the part number for their project.

Because these are vintage components, minor surface variations or packaging wear may be present; however, the part pictured is the exact unit being sold.
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.
