GM Engine Mount Small Clamshell

The GM Engine Mount Small Clamshell from PROTHANE is a polyurethane motor mount insert designed to replace worn OEM rubber mounts on General Motors vehicles from 1973 to 1993. This product is particularly useful for mechanics and car enthusiasts looking to enhance engine stability and performance.

The small clamshell design fits into the existing mount cavity without requiring bracket modification, making installation straightforward. PROTHANE's polyurethane formulation offers superior resistance to heat, oil, ozone, and UV degradation compared to factory rubber compounds, ensuring a longer service life. This insert reduces engine movement under load, leading to improved throttle response and a tighter shift feel.

This mount insert is ideal for owners of classic and vintage GM engine platforms, including Chevrolet small-block and big-block engines, as well as Buick V8 applications. Its black color indicates UV-stabilized material, which is critical for longevity in vehicles that see regular use or performance driving.
