The Buffer, engine mounting (0946DG) secures the engine while absorbing vibration and torque movement. Replacing worn mounts with Porza quality restores quiet operation and drivetrain alignment.
A buffer for an engine mounting is a damping component, usually made of rubber or elastomer, that is part of the engine mount system. Its function is to absorb vibrations and shocks generated by the engine, reducing noise and preventing these vibrations from being transmitted to the vehicle chassis. This improves driving comfort and protects surrounding components.
Key specifications include dimensions, hardness (durometer), material type, and compatibility with the specific engine mount design. Buffers are typically made from durable rubber or elastomer compounds that can withstand continuous vibration, load, and temperatures commonly ranging from -40°C to +120°C. Proper elasticity and resilience are essential for effective vibration damping.
Replacement is necessary when the buffer becomes worn, cracked, hardened, or loses its elasticity. Common symptoms include increased engine vibration, noise, or movement. A degraded buffer can reduce the effectiveness of the engine mount and lead to additional wear on other components.
Porza offers a fit guarantee option where your vehicle details or technical specifications are checked against product data. This ensures the buffer matches the correct size, material, and design for your engine mounting system.
Porza supplies high-quality engine mounting and vibration control components with fast delivery across Europe. Customers can order online or choose in-store pickup in the Netherlands, Germany, or Belgium. This allows quick and reliable maintenance for both professional workshops and individual users.
If you select the fit guarantee, Porza verifies compatibility before shipment. If the product does not fit or meet expectations, it can be returned according to the return policy. This ensures a reliable and risk-free purchasing experience.
