This original GM interior component is an excellent opportunity for restorers seeking authentic factory-correct parts for some of Chevrolet’s most iconic vehicles.

The 1955–1957 Chevrolet lineup, commonly known as the “Tri-Five Chevrolets,” remains among the most celebrated American automobiles ever built. Renowned for their styling, performance potential, and cultural significance, these models continue to be highly sought after by collectors worldwide.

Likewise, the first-generation Corvette (C1) produced from 1953 through 1962 helped establish Chevrolet’s reputation in the sports car market. Today, C1 Corvettes are among the most desirable and valuable American classics.

The seat adjuster knob is a small but important interior component that allows occupants to operate the seat adjustment mechanism. While often overlooked, these knobs contribute to both the functionality and originality of the vehicle’s interior.

Over time, original knobs frequently become cracked, worn, broken, faded, missing, or damaged through years of use. Because interior hardware is highly visible during judging and restoration inspections, replacing damaged components with genuine GM parts can significantly enhance the authenticity of a restoration.

This seat adjuster knob was manufactured by General Motors during the original production era and remained unused in inventory. Unlike reproduction components, it retains the original factory design, materials, dimensions, and appearance intended for Chevrolet production vehicles.
