Chevrolet Silverado 3500HD Support Mount - Right - RustBuster - `11-`18. This right-side core support mount is designed for 2011–2018 Silverado 3500HD trucks and serves as a direct replacement for a worn or rusted factory mount. It’s made for owners who want a reliable repair part that addresses core support stability and corrosion issues commonly found on older heavy-duty trucks.

The RustBuster right support mount restores the mounting point for the core support assembly to maintain proper alignment of radiator and front-end components. By replacing a damaged or corroded bracket, this part helps reduce movement and vibration at the front-end and simplifies reassembly after collision repair or routine front-end work. The part is intended as a practical, vehicle-specific replacement that fits the right-side location on compatible Silverado 3500HD models.
