Product Description
Genuine Michigan R7020CAP.020 Rod Bearings (NORS)
This genuine Michigan R7020CAP.020 connecting rod bearing set is New Old Replacement Stock (NORS), designed for a wide range of 1955-1974 General Motors 6-cylinder and V8 engines. Manufactured in the USA by Michigan Engine Bearings, a division of D.A.B. Industries, Inc., this set provides reliable performance for your classic vehicle's engine rebuild. These bearings are .020" undersize, intended for a crankshaft that has been ground down by .020 inches. This specific box contains 6 pairs of rod bearings, making it a complete set for 6-cylinder applications or a partial set for V8 engines requiring this specific bearing.
Crucial Buyer Application Note: This box contains a vintage 6-Pair (12 half-shells) rod bearing kit manufactured by Michigan Engine Bearings for commercial engine remanufacturers. These shells share the standard industry dimensions of the Clevite CB-663 series, built for a 2.000" rod journal.
- For Inline-6 Engines: This is a 100% complete, full engine set for the Chevy/GMC 194, 230, and 250 configurations.
- For Inline-4 Engines: This provides enough for a full engine build (4 pairs used) with 2 extra pairs left over.
- For V8 Engines: While these bearing shells physically fit the classic GM V8 configurations listed above (including Chevy Small Journal V8s and Buick/Olds/Pontiac 215/300 V8s), a V8 engine requires 8 pairs total. This box is a partial set for V8 builders, and you will need to source 2 additional pairs to complete your assembly.
Fits crankshafts professionally machined to .020" Undersize only.

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.
