Engine Mountings & Bushes

What are engine mountings & bushes?

Engine mountings and bushes are components that serve as protective connections between the engine and the chassis of the vehicle. These mountings and bushes ensure that the engine is secured in place but still have some element of movement as forces around the engine change with the physics of power transfer and the driving conditions.

There are different types of engine mountings. These are:

• Standard rubber, PU or metal engine mountings

• Hydraulic engine mountings

• Electric (active) engine mounting
