1937–1941 Chevrolet Passenger Car NOS Rear Axle Bearing Inner Race #IR1500 (OEM #111120)

Available for sale is a genuine New Old Stock (NOS) Rear Axle Bearing Inner Race, part number IR1500, corresponding to OEM Chevrolet part #111120, designed for 1937–1941 Chevrolet passenger car applications. This original vintage service replacement component is a rare and important drivetrain part for restorers seeking factory-correct rear axle components for pre-war Chevrolet restorations.

The 1937–1941 Chevrolet passenger car lineup represents one of Chevrolet’s most successful pre-war generations, featuring improved styling, enhanced ride quality, and dependable engineering. These vehicles remain highly collectible today, and maintaining authentic drivetrain components is essential for preserving both originality and performance.

The rear axle bearing inner race serves as the hardened precision-machined surface on which the bearing rollers operate. Together with the axle bearing assembly, it supports the axle shaft, carries vehicle loads, and allows smooth rotation of the rear axle. Proper bearing and race condition are critical for minimizing friction, reducing wear, and maintaining drivetrain reliability.

Over decades of operation, original bearing races can become worn, pitted, scored, corroded, or damaged due to age, mileage, contamination, and lubrication breakdown. Replacing worn races during a rear axle rebuild helps restore proper bearing operation and extend the service life of the axle assembly.

This component is a true New Old Stock (NOS) service replacement part, meaning it was manufactured during the original production and service era and has never been installed. It retains original dimensions, machining tolerances, and material specifications intended for proper fitment and dependable performance.

Unlike used components, an unused NOS bearing race provides a fresh precision bearing surface and is especially desirable for high-quality restorations, concours projects, and drivetrain rebuilds.

For collectors and restoration professionals, using authentic-era Chevrolet drivetrain components helps preserve historical accuracy, maintain vehicle value, and ensure reliable operation.

As original pre-war Chevrolet rear axle service parts become increasingly difficult to locate, NOS components such as this bearing inner race continue to be highly sought after by enthusiasts and restorers.
