HRD Precision Machined Subaru WRX/STi Transmission Mount - Midnight Navy

If you're in pursuit of a tighter feeling chassis that puts power down more effortlessly, you've come to the right place. Our HRD Precision Machined Transmission Mount is machined from billet 7000-series alloy for superior strength characteristics, featuring our 80A dual duty durometer bushings, and Titan Frost Ti bushing pins. This component doesn't just look beautiful, it helps in transforming how your WRX or STi delivers power.

Engineered for Uncompromising Strength

We precision machine our transmission mount from 7000-series billet aluminum despite the increased costs associated with the material. Why? Because we've over-engineered this component by choice. When you're dealing with the violent back-and-forth forces placed on your transmission, especially with higher power builds, maximizing strength comes before all else. 

Fits both 6MT and 5MT Subaru WRX/STi Platforms

Included with each of our transmission mounts is an adapter plate for 5MT transmissions. If you're running a 6MT Subaru WRX or STi, easily bolt on the transmission mount as is, no adapter. If you're running a 5MT Subaru WRX (2002-2014), simply place our included adapter plate on the Titan Frost Ti studs during install.

Built to OEM+ Specifications

We've specified our 80A dual duty bushings for this component after much testing. We found that the combination of this durometer in our poly blend with the overall design of our transmission mount yielded the best results. As a result, NVH is only minimally increased from your OEM component while you benefit from keeping your transmission locked down in a way that is not otherwise possible. Our transmission mount is at home on your daily commute as much as it is chasing the podium.

The End Result

Integrating our transmission mount with your build will bring a much tighter feeling to your drivetrain. You will feel more connection to your drivetrain, tighter shifts and improved on/off throttle behavior, and enhanced confidence in your power delivery. This is a modification for drivers who are chasing the best power delivery and shifting experience possible, complementing our pitch stop and differential brace. After your first drive, you'll be wondering why you hadn't done this modification sooner.
