Diagram Ref No 23
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.
