DESCRIPTION
Improve your Porsche's handling performance, steering precision and gearbox shifting with a Powerflex PFR57-521 bushing. PFR57-521 and PFR57-521BLK fits models in Position #20 in the Bushing Diagram.
Porsche Boxster and Cayman factory front engine mount bushings are particularly prone to cracking because of the large amount of voiding in the rubber material. If left unchecked, the rubber will continue to wear and knocking sounds may appear as you accelerate, brake and turn. Gear changes also become sloppy and lose precision.
The Powerflex Front Engine Mount Bushing Insert is a solution to prevent failure of the factory part. If your stock bushings are in poor condition see our engine mount bushing replacement (bottom of page) which will replace and improve the factory bushing design.

PRODUCT WARRANTY
PowerflexUSA's limited Lifetime Warranty reflects confidence in both their products and also the history of fanatical customer service.
PowerflexUSA does not have a time-based warranty policy because issues that customers have are always an opportunity to learn. Where a problem has occurred due to incorrect fitting, we have always asked if the reason for the error was due to poor fitting instructions. When a part fails, we strive to understand if the part is being used outside of its design parameters. And like all manufacturing we have had the occasional material quality issue and in these cases, we have always replaced parts without question.
For warranty service please see the below instructions:
- Contact Powerflex USA directly via their online Warranty Page.
- Note the ViVA Performance Order ID associated with the bushing; including details of the installation and any changes made, with photos of the failed part.
- The Warranty only applies to parts purchased from ViVA Performance.
- The Warranty is limited to the replacement of suspension bushings supplied.
- There is no Warranty coverage for consequential part failure or labor for installation.
- The Warranty applies to the original purchaser only, no exceptions.
