HD transmission mounts for your 964 C4 can provide significant performance benefits to any owner. These mounts are constructed from 25% stiffer rubber than stock, offering an RS comparable part at a fraction of the price. Thanks to their rubber construction, these mounts can offer these benefits all without significantly increased NVH. This makes them an ideal upgrade for those with worn original parts who want significantly improved shifter feel and weight transfer properties. All of these benefits come without making your car feel like a racecar like semi-solid or solid mounts tend to do. If you are going to be going through the effort of changing the transmission bushing, you definitely don't want to miss the chance to make this sensible, inexpensive upgrade.

Eliminate drivetrain slop and restore crisp gear changes with this HD Transmission / Gearbox Mount Bush.
Designed for the Porsche 964 C4, this heavy-duty mount uses a stiffer, high-durometer rubber compound (approximately 25 % firmer than factory rubber) to control gearbox motion and maintain precise alignment under load.
Sold Each.

What This Product Does:
- Securing the Transmission - It keeps the transmission firmly in place, resisting movement under torque, acceleration, or deceleration.
- Absorbing Vibration & Noise - The rubber or elastomer element isolates drivetrain vibrations so they don't transmit harshly into the cabin.
- Controlling Movement / Deflection - Under load, transmissions tend to twist or shift slightly. A stiffer mount reduces that movement, improving shift feel, drivetrain alignment, and response.
- Maintaining Drivetrain Geometry - By limiting transmission motion, it helps preserve correct angles and alignment of drive shafts, couplings, and linkage.
- Clunks or thuds when shifting or applying torque
- Movement or slop in the transmission under load
- Delays or vagueness in shifts due to misalignment
- Excess vibration or drivetrain shake in the cabin
- Wear or stress on driveline components (e.g. drive shafts, joints)
- The transmission might feel “loose” under acceleration or deceleration
Why Upgrading Matters:
- Improved Shift Feel & Precision - A stiffer mount reduces movement that can dull shift quality or introduce slack.
- Better Drivetrain Alignment Under Load - Less motion keeps the transmission geometry stable, which protects driveshafts, joints, and couplers.
- Sharper Response - With less flex, the car responds more directly to throttle inputs without drivetrain “lag.”
- Balance of Comfort and Control - The HD rubber design offers more rigidity than stock but isn’t as harsh as solid mounts, so you still retain usable vibration isolation.
- Durability - A stiffer compound is more resistant to deformation, aging, oil, and heat, giving longer service life.
- Cost-Effective Upgrade - If the original bushing is degraded, installing an HD version is often a worthwhile performance upgrade.
