Description
Powerflex Lower Engine Mount Insert (Black Series) for Mercedes-Benz A, CLA, & GLA Class.
Function and design
The engine and transmission mounting system reacts to changes in drivetrain torque while isolating vibration from the body. A change in mounting compliance influences how much the assembly moves as load is applied or released.
What to consider
A firmer mounting arrangement trades some isolation for movement control. Increased noise, vibration or harshness may be noticeable, particularly at idle; a firmer option should be chosen with the vehicle's intended use in mind.
Application
Mercedes-Benz A, CLA, & GLA Class.
Technical details
- Construction: reinforcement insert for the compatible original mounting arrangement. It is not a complete replacement mount; the retained mount must be suitable for reuse.
Series
- Black Series: the firmer series generally intended to prioritize movement control. Product-specific fitment and intended-use restrictions still apply.
