The GKTech Polyurethane Transmission Mount is a high-performance, direct replacement for the factory transmission mount found in the Nissan 350Z (Z33) and Infiniti G35. Designed to reduce drivetrain movement under load, this mount provides sharper throttle response, more consistent gear engagement, and greater drivetrain stability, making it ideal for both street-driven performance cars and track builds.
Machined from 6061-T6 billet aluminum and paired with polyurethane bushings, this mount strikes the perfect balance between comfort and performance. It also includes two bushing options, allowing you to tailor the stiffness to your driving style.
