The OE Match Gearbox Silencer Block is a high-quality replacement mounting component designed to isolate and dampen vibration and noise generated by the gearbox and drivetrain. Installed between the transmission assembly and vehicle mounting points, the silencer block helps absorb drivetrain movement and reduce the transmission of vibration into the chassis and passenger compartment.
Fits:
- Porsche 964 (911) C2 1989-93 MANUAL (Gearbox type G50.03 / G50.04 / G50.05) TIPTRONIC (Gearbox type A50.02 / A50.03)

Manufactured to OE specifications using durable rubber and metal construction, this replacement silencer block restores the original levels of comfort, refinement and drivetrain support. It is an ideal replacement for worn, cracked or deteriorated original mounts commonly found on ageing Porsche vehicles.
What This Product Does:
- Isolates gearbox and drivetrain vibrations from the chassis.
- Reduces transmission noise entering the passenger compartment.
- Supports the gearbox while allowing controlled movement.
- Helps maintain correct drivetrain alignment.
- Minimises shock loads during acceleration and gear changes.
- Improves driving comfort and refinement.
Symptoms Of Wear Or Failure:
- Increased vibration felt through the cabin.
- Excessive drivetrain movement during acceleration or deceleration.
- Clunking or knocking noises when changing gear.
- Harsh engagement during gear shifts.
- Visible cracking, splitting or deterioration of the rubber mount.
- Sagging or misalignment of the gearbox assembly.
- Increased transmission noise within the vehicle.
- Premature wear of surrounding drivetrain components.
Why Replacement Matters:
- The gearbox silencer block is continuously exposed to drivetrain torque, engine vibration, road shock, heat and age-related deterioration. Over time, the rubber element can harden, crack or separate from its metal mounting surfaces, reducing its ability to absorb vibration and support the transmission correctly.
- A failed silencer block can allow excessive gearbox movement, leading to increased vibration, drivetrain noise and additional stress on transmission mounts, couplings and related components. If left unresolved, excessive movement may contribute to accelerated wear throughout the drivetrain system.

High Density transmission mounts are the perfect compromise between stock rubber and our Semi-Solid mounts. Their heavy duty 25% higher durometer rubber construction makes them ideal for performance oriented cars but still allows absorption of vibrations and noise associated with solid mounts. Installs in stock transmission mount bracket replacing worn out factory rubber.
