Gearbox Mount Bushings Set for Porsche 911 G50 (1987–1989). This rubber mount set restores gearbox stability, reduces vibration, and maintains proper drivetrain alignment under load.
Sold As A Set Of 2 bushes (4 halves).

Fits On To Diagram Ref No 1
What This Product Does:
- Support & locate the gearbox - The mounts hold the transmission housing securely to the chassis or subframe, maintaining alignment between the gearbox and the driveshafts.
- Dampen vibration & isolate noise - The rubber or elastomer in the bushings absorbs vibration from the transmission and drivetrain, preventing harshness from transferring into the cabin.
- Limit movement under torque - Under acceleration, deceleration, or shifting loads, the gearbox wants to twist or shift slightly. The mount bushings resist that motion, constraining it to acceptable levels.
- Maintain geometry & protect components - A stable mount ensures the angular relationships and alignment of the drivetrain (driveshafts, couplings, mounts) remain correct under load.
- Clunking, thuds or knocks from the gearbox area when shifting or under throttle
- Increased drivetrain vibration felt in the cabin
- Loose or laggy gear shifts, or slight misalignment registering as “play”
- Excess movement / twist of the gearbox under load
- Stress or wear on driveshafts, universal joints, or coupling components
- Noise under load changes — e.g. when engaging or releasing throttle
- Restores drivetrain stability and response — tighter mounts reduce slack that dulls shift feel and throttle response
- Protects other drivetrain parts — controlling movement reduces undue stress on joints, couplings, and shafts
- Maintains alignment & lug angles — consistent mounts help preserve correct geometry even under load
- Eliminates noise & vibration due to degraded bushings
- Ensures proper operation — a failing mount can cause accelerated wear or even damage
- Maintains value & reliability — restoring mount integrity is important for longevity, performance restoration, and driver satisfaction
