Volvo Truck Engine Mount - Part 551 549 77

Part 551 549 77 (also written 5515497-7) is an OEM-specification engine mount for Volvo FH, FM, and FMX heavy trucks with D11/D13 diesel engines. Isolates the powertrain from the chassis frame, preventing vibration from reaching the driver cabin and causing premature chassis fatigue. Features hydraulically damped design with controlled fluid flow for superior isolation at idle while maintaining firm engine control during acceleration. Very low competition in US search results - an excellent opportunity for aftermarket supply. Volvo Trucks North America is headquartered in Greensboro, NC with a large US truck fleet requiring ongoing mount replacement.

Manufactured by HAMM Mount in our ISO 9001:2015 certified facility using advanced vulcanization technology and premium rubber compounds. Every unit undergoes multi-stage quality control including dimensional inspection, hardness verification, and load-deflection testing. Fire safety compliance per EN 45545-2 is verified for all railway applications.
