IAG Comfort Series Pitch Stop Mount 55A Black 02-25 WRX / 02-21 STI / 05-09 Legacy / 04-11 Forester

The IAG Comfort Series Pitch Stop Mount is engineered for drivers who want improved drivetrain stability without sacrificing everyday comfort. This billet aluminum mount is a durable upgrade over the factory plastic Subaru pitch stop, helping to reduce drivetrain slop while maintaining a smooth, quiet driving experience. Equipped with four 55A durometer bushings—the softest in IAG’s lineup—it delivers dependable performance with minimal NVH for daily-driven vehicles.

The IAG Comfort Series Pitch Stop Mount is precision CNC-machined from 6061 billet aluminum in IAG’s Westminster, Maryland facility, offering a significant durability upgrade over the OEM mount, which is prone to premature wear. A black anodized finish adds corrosion resistance and long-term protection, ensuring the mount can withstand the demands of the drivetrain while retaining comfort-focused performance characteristics.

Installation is straightforward for anyone comfortable working on their own vehicle. With basic hand tools and minimal garage time, the IAG Comfort Series Pitch Stop Mount can typically be installed in approximately 30 minutes to one hour, depending on the vehicle and setup.

A key feature of the IAG Comfort Series Pitch Stop Mount is its interchangeable bushing design, allowing you to fine-tune stiffness as your performance needs evolve. While the included 55A bushings provide a soft, dampened ride with minimal noise, vibration, and harshness, stiffer options are available for more aggressive driving. These include the 75A Street Series Bushings, 90A Competition Series Bushings, and Solid Steel Race Bushings, which significantly increase stiffness over both stock and Subaru Group N mounts (sold separately).
