Description
Powerflex Engine Mount Bushings (PFR57-415H) for 1965–1989 Porsche 911.
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
1965–1989 Porsche 911.
Technical details
- Construction: replacement mounting bushing. Confirm the original housing or bracket arrangement; a bushing listing does not imply that a complete mount or bracket is included.
