GrimmSpeed Street Transmission Mount | Subaru 5MT, 6MT

Product Description

The GrimmSpeed Transmission Mount is designed for Subaru 5MT and 6MT manual transmissions, offering a substantial upgrade over OEM chassis mounts. Prioritizing low NVH (noise, vibrations, and harshness), OEM mounts often compromise on performance. This mount, which complements the GrimmSpeed Pitch Stop Mount, provides a stiffer drivetrain feel, allowing for more predictable shifting and increased confidence during spirited driving.

Key Features

• Enhanced Performance: Features 75A durometer polyurethane bushings to prevent transmission movement under high torque without excessive noise and vibration.
• OEM Fitment: Fits almost all AWD Subaru manual transmission setups. Includes a 5-Speed Adapter Spacer for compatibility with both 5-speed and 6-speed models.
• Robust Construction: Made from 6061 billet aluminum and 304 stainless steel, providing exceptional strength and durability.
• Ease of Installation: OEM-inspired press-fit stud minimizes misalignment and hardware damage. Mount arrives fully assembled with all required mounting hardware included.
