Features & Product Details

If your transmission feels like it has excessive vibration or movement under normal driving conditions, then this can be an indicator that your factory transmission mount has failed. Over time and miles, your mounts whether they be motor mounts or transmission mounts can be prone to failure. And if you have performed moderate modifications then the added torque can certainly affect the stability of the transmission. 

You can restore order in your vehicle with the STI JDM Group N Gearbox Mount. This transmission mount features strong metal construction with super durable urethane bushings to absorb road vibration. Once installed, your transmission will remain secured for years to come.

Good upgrade! Installed together with Group N Transmission Mount, Group N Pitch Stop Mount, Group N Right Side Engine Mount, Group N Left Side Engine Mount. The whole car feels much tighter and more direct feedback. It also improved on the car handling. There is a little vibration noise, but can be ignored.
