Poly Motor Mount Kit Freightliner

The M17338KUB Poly Motor Mount Kit for Freightliner trucks, available through Wofford Truck Parts, is engineered to provide high-performance engine mounting for heavy-duty applications. Designed for use on models including the Century, Columbia and M2 series, this kit replaces the standard rubber mounts with polyurethane components for improved longevity and reduced deflection. It cross-references to OEM part numbers SSB33-1000-2 and M17338K2. By upgrading to poly-mounting, you reduce engine movement under load, minimize vibration transmission to the chassis, and maintain better alignment of engine/drivetrain components. This results in fewer failures, quieter operation and longer drivetrain life—ideal for service trucks, long-haul rigs and fleet operators demanding reliability.
