1938–1952 Chevrolet Passenger Car NOS Exhaust Muffler U-Bolt #377916

Available for sale is a genuine General Motors New Old Stock (NOS) Exhaust Muffler U-Bolt, GM part number 377916, designed for 1938–1952 Chevrolet passenger car applications. This original GM service replacement component is a rare and highly desirable exhaust system hardware item for restorers seeking authentic factory-correct parts for pre-war and post-war Chevrolet restorations.

The Chevrolet passenger cars produced between 1938 and 1952 represent an important era in American automotive history. These vehicles carried Chevrolet through the pre-war years, wartime production interruptions, and the post-war automotive boom. Models from this period remain popular among collectors due to their classic styling, historical significance, and straightforward mechanical design.

The exhaust muffler U-bolt is a simple yet essential component of the exhaust system. It is used to securely clamp and support the muffler and related exhaust components, helping maintain proper alignment while preventing leaks and unwanted movement caused by vibration and road conditions.

Over time, original exhaust hardware is often lost, corroded, damaged, or replaced during routine maintenance and exhaust repairs. For restorers pursuing an authentic restoration, locating correct factory-style hardware can be just as important as finding major mechanical components.

This component is a true New Old Stock (NOS) GM service replacement part, meaning it was manufactured during the original production era and has never been installed on a vehicle. It retains original factory dimensions, material specifications, and engineering design intended for proper fitment and long-term durability.

Unlike generic modern replacement hardware, NOS GM exhaust components provide authentic appearance and correct construction, making them ideal for concours restorations, show vehicles, and historically accurate projects.

For restoration enthusiasts, attention to detail matters. Correct exhaust hardware helps preserve originality and ensures the exhaust system remains securely mounted and properly functioning.

As original GM exhaust hardware from the 1930s, 1940s, and early 1950s becomes increasingly difficult to locate, NOS parts such as this muffler U-bolt have become highly sought after by collectors and restoration professionals.
