Available for sale is a genuine General Motors New Old Stock (NOS) Body Mount Cushion, GM part number 3748937, designed for select 1955, 1956, and 1957 Chevrolet 150, 210, and Bel Air passenger car applications. This original GM service replacement component is a valuable find for restorers seeking authentic chassis and body mounting parts for their Tri-Five Chevrolet restoration.

The 1955–1957 Chevrolet lineup, commonly known as the Tri-Five Chevrolets, represents one of the most iconic eras in American automotive history. Renowned for their distinctive styling, innovative engineering, and legendary performance potential, the 150, 210, and Bel Air models remain among the most collectible and desirable classic cars ever produced by Chevrolet.

The body mount cushion is a critical component located between the vehicle’s body and frame. Its primary purpose is to absorb vibration, reduce road noise, and provide proper spacing and support between the chassis and body structure. These cushions help maintain body alignment while improving ride quality and protecting the vehicle from excessive stress and vibration.

Over decades of service, original body mount cushions often become compressed, cracked, hardened, deteriorated, or completely unusable due to age, weather exposure, moisture, and normal wear. Worn body mounts can lead to poor body alignment, increased vibration, squeaks, rattles, and reduced ride comfort.

This component is a true New Old Stock (NOS) GM service replacement part. Manufactured by General Motors during the original production era and never installed on a vehicle, it retains the original factory specifications, dimensions, materials, and engineering standards intended for these applications.

Unlike many reproduction components, genuine NOS body mount cushions offer authentic factory construction and fitment. For restorers pursuing originality, using original GM mounting components helps preserve the integrity and authenticity of the restoration while ensuring proper body-to-frame alignment.

Body mount cushions are often overlooked during restoration projects, yet they play a vital role in the overall quality of the finished vehicle. Properly functioning mounts contribute to improved ride quality, reduced vibration, and correct body positioning. Replacing aged or damaged mounts is frequently an important step during frame-off restorations.

Whether you’re restoring a Bel Air convertible, hardtop, sedan, wagon, a Chevrolet 210, or a Chevrolet 150, this NOS body mount cushion provides an excellent opportunity to install a genuine GM component designed specifically for these classic vehicles.

As original GM service inventories continue to diminish, authentic NOS chassis and body mounting components have become increasingly difficult to locate. Collectors and restoration professionals recognize the value of genuine factory parts because they help preserve both the originality and long-term value of the vehicle.
