SACHS, FORMULA, SUPERPRO, MCA, POLYAIR Body Mount Bushes

Body mount bushes provide a cushioned connection between a vehicle's body or cabin and its chassis or frame. They help isolate vibration and harshness while supporting the body in its intended position relative to the chassis.

As body mount bushes age and deteriorate, they can allow more movement between these structures and reduce their ability to isolate vibration. Replacing worn bushes helps restore the connection between the body and chassis and maintain the isolation these components are designed to provide.

Fulcrum Suspensions offers body mount bushes and body mount bush kits for a range of mounting positions and applications, including polyurethane replacement options for long-term durability.

What Are Body Mount Bushes?

Body mount bushes are flexible mounting components positioned between the vehicle body and chassis at designated mounting points.

Rather than rigidly connecting the two structures, the bushes provide a degree of isolation. This helps limit the transfer of vibration and harshness from the chassis into the body and cabin while maintaining a secure mounting point.

Depending on the vehicle design, body mounting arrangements can include front and rear body mounts, cabin-to-chassis mounts and other supporting mounting positions.

Body mount bushes are different from suspension bushes such as control arm or sway bar bushes. Their primary role is associated with mounting and isolating the body or cabin rather than controlling the movement of an individual suspension component.

How Body Mount Bushes Reduce Vibration and Movement

A vehicle's chassis is exposed to vibration and movement from the road, drivetrain and other mechanical components.

Body mount bushes help isolate some of this vibration before it reaches the body and passenger compartment. At the same time, they support the relationship between the body and chassis.

The bush material needs to provide an appropriate balance between support and isolation. Too much unwanted movement can affect how securely the body is supported, while the mounting system must still provide sufficient isolation from chassis vibration and harshness.

This makes body mount condition particularly important as vehicles age.

Worn Body Mount Bushes

Body mount bushes are subjected to compression, movement and environmental exposure throughout their service life. Over time, the material can deteriorate, compress, crack or lose its original properties.

Worn body mounts can allow additional movement between the body and chassis and may reduce their ability to isolate vibration.

Depending on the vehicle and severity of wear, deterioration may be associated with increased cabin vibration, rattling or clunking, additional body movement or visible deterioration around the mounting points.

A visual inspection can help identify cracked, compressed or damaged bushes. However, noises and vibration can have many causes, so the complete mounting and chassis system should be inspected before assuming body mount bushes are responsible.

Replacing worn body mounts with the correct components helps restore the intended body-to-chassis connection and isolation.

Polyurethane Body Mount Bushes

Polyurethane is commonly used as an aftermarket replacement material for automotive bushes because it can provide durable and consistent support. Polyurethane body mount bushes can be particularly useful where durability and resistance to repeated loading are priorities.

Material alone, however, should not determine which body mount bush you choose. The bush dimensions, mounting position and intended vehicle application also need to be correct.

Always select body mount bushes according to the specifications of the individual product and its intended application.

Body Mount Bush Kits and Mounting Positions

Body mount configurations vary considerably between vehicles.

Some applications use separate front and rear body mounts, while others can have different bushes at individual body, cabin or support mounting positions. Fulcrum's current range reflects this variation, with complete body mount bush kits alongside bushes for specific front, rear and supporting mounting locations.

A body mount bush kit can provide the components required for a particular mounting arrangement, but kit contents differ by application.

For this reason, it is important to check exactly which mounting positions are covered rather than assuming every body mount bush kit replaces every mount on the vehicle.

Choosing the Right Body Mount Bushes

Start by confirming the correct application and mounting position.

If you are replacing existing body mounts, identify which bushes require replacement and inspect surrounding mounting points and hardware at the same time.

Consider whether you require an individual body mount or a body mount bush kit covering multiple positions. Product specifications should indicate the intended mounting location and application.

Universal body mount bushes are also available for suitable applications, but dimensions and installation requirements need to be checked carefully. A universal component should not be assumed to fit simply because its general design appears similar.

Correct installation is important because body mounts form part of the connection between the body and chassis. If you are uncertain about the correct parts or installation procedure, professional inspection and fitting can help ensure the appropriate components are used.
