The Powerflex PFR57-415 Engine Gearbox Mount Bush is designed for owners of classic Porsche 911 models (1965-1989) who are looking to restore or enhance their vehicle's handling and drivetrain stability. By replacing standard, ageing rubber mounts, these high-performance polyurethane bushes provide a sharper driving feel and improved safety, though users should note that stiffer materials may introduce a slight increase in vibration compared to factory-spec rubber.

While the material is firmer than original rubber, most drivers find the increase in tactile feedback far outweighs any minor increase in vibration.
No, these are designed to be installed without specialized heavy-duty press tools.
The PFR57-415 kit contains 2 bushes.
No, this part is specifically engineered for the 1965-1989 model years.
Beyond a basic inspection during regular oil changes to check for mounting security, they are largely maintenance-free.
Ensure that the mounting bolts are torqued to the specific factory settings for your Porsche 911 model; overtightening can amplify vibration.
Thoroughly clean the mounting housing of all remnants of the old rubber and apply sufficient silicone grease to the outer surface of the polyurethane bush.
This kit includes 2 pieces for the gearbox mount area. Installation is straightforward as it replaces standard rubber bushes directly; however, ensure you fully clean the metal housing of any remaining rubber residue before inserting the Powerflex units. Use a high-quality silicone grease (usually provided by Powerflex) to coat the bushings to prevent squeaking. Regularly inspect the bushes during your annual service to ensure they remain free of debris. This product is compatible exclusively with Porsche 911 models manufactured between 1965 and 1989.
