IAG Comfort Series 55A Transmission Bushing Kit for IAG Transmission Mounts

Designed with daily-drivers in mind, the IAG Comfort Series 55A Transmission Mount Bushing Kit provides a soft, dampened ride while minimizing NVH (Noise Vibration Harshness). This set of 55A durometer comfort bushings is compatible with all IAG EJ and FA Comfort, Street, Competition and Race Series Transmission Mounts, offering a customizable approach to drivetrain performance.

A standout feature of IAG’s Transmission Mounts is their interchangeable design, letting you adjust the bushing stiffness as your performance needs evolve. While the included 55A durometer bushings will provide you with a quiet, comfortable ride, we also have stiffer options for high-performance applications. The next step up is our 75A Street Series Bushing Kit, Competition Series Red 90A Bushing Kit, and finally, our Solid Steel Race Bushings that significantly increase the stiffness and NVH over the stock and GROUP N mount (sold separately).

IAG’s Transmission Bushings are tougher than rubber because they’re made from durable polyurethane material. Polyurethane bushings deliver enhanced handling and stability by minimizing friction and offering strong load-bearing performance. They are exceptionally wear-resistant and can endure exposure to motor chemicals, road salts, and various environmental factors, making them the perfect match for IAG's high-performing transmission mounts.

Once the transmission mounts are out of the car, swapping out the bushings in the IAG Transmission mounts only takes a couple more minutes. Installation of the transmission mounts themselves is a straightforward task because it features a unique flush hardware design that eliminates the need to take the mount apart to install it on the vehicle. Removing the transmission mounts takes around thirty minutes to complete using basic hand-tools and a jack with jack stands.
