Rubber engine mounts are a type of mount used to secure the engine to the frame of a vehicle. They consist of a metal bracket on one side and a rubber bushing on the other. The metal bracket attaches to the engine, while the rubber bushing attaches to the frame. The rubber bushing acts as a cushion, absorbing vibrations and shocks from the road, and reducing the transfer of these vibrations to the rest of the vehicle. This helps to improve the overall ride comfort and reduce noise and harshness inside the vehicle. Rubber engine mounts also help to isolate the engine from the frame, which can help to reduce wear and tear on the engine and other vehicle components.
