1953–1962 Chevrolet Corvette C1 NOS Lower Control A-Arm Bumper Set #3661888

Available for sale is a genuine General Motors New Old Stock (NOS) Lower Control A-Arm Bumper Set, GM part number 3661888, designed for 1953–1962 Chevrolet Corvette C1 applications. This original GM service replacement component is a rare and highly desirable find for restorers seeking factory-correct suspension parts for America’s first-generation sports car.

The 1953–1962 Chevrolet Corvette C1 laid the foundation for one of the most iconic performance cars in automotive history. From the original 1953 roadster through the final solid-axle 1962 model, the Corvette combined distinctive fiberglass body styling with Chevrolet engineering to create a true American sports car. Today, C1 Corvettes remain among the most collectible and sought-after classic vehicles in the world.

The lower control arm bumper, commonly referred to as a lower A-arm bumper or suspension stop bumper, is an important component of the Corvette’s front suspension system. It is designed to absorb impact and cushion suspension movement when the control arm reaches the limits of its travel. This helps prevent metal-to-metal contact, reduces stress on suspension components, and contributes to proper ride quality.

Over time, original rubber bumpers can deteriorate from age, heat, environmental exposure, and years of service. Hardened, cracked, flattened, or missing bumpers can result in harsh suspension operation, increased noise, and unnecessary wear on valuable suspension components. Replacing worn bumpers is a critical step in restoring the suspension to factory specifications.

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

Unlike modern reproduction parts, genuine NOS GM suspension components provide authentic fit, appearance, and material quality. For collectors pursuing factory-correct, NCRS, or concours-level restorations, original GM service parts remain highly valued and increasingly difficult to find.

The Corvette’s suspension system was carefully engineered to provide a balance of comfort and responsive handling. Maintaining proper suspension bumpers helps preserve those characteristics while protecting critical front-end components from excessive impact loads.

Whether you’re restoring an early Blue Flame six-cylinder Corvette, a fuel-injected performance model, or a late-production 1962 Corvette, these lower control arm bumpers provide an authentic and reliable restoration solution.

As original Corvette suspension service parts continue to become more difficult to locate, NOS components such as this bumper set have become highly sought after by collectors, Corvette specialists, and professional restorers.
