POWERFLEX Fiesta ST transmission mount insert (street or race)
Urethane insert to fill the voids in the original rubber transmission mount. The original rubber mount is built for absolute noise and vibration suppression. The soft rubber soaks up NVH to make the driveline quieter and more forgiving. But for many enthusiasts the stock rubber has too much comfort and not enough performance. Powerflex offers multiple bushing options for those looking to improve feel and response.
These urethane inserts take up the spaces in the stock rubber bushing. Simply pop these into place for an easy and hassle-free upgrade. The stiffer urethane works with the stock rubber to reduce movement and deflection. Inserts are an effective way of reducing engine and transmission movement, improving power delivery and sharpening gear shifting. Inserts can also prolong the life of the stock bushing now that it cannot flex as much.
