A silentblock is a vibration-isolating mounting component designed to provide a degree of cushioning between adjoining parts. It helps absorb movement and vibration while supporting the component in its intended position. On these classic Porsche Targa applications, the silentblock bearing forms part of the associated Targa mounting assembly shown under diagram reference 34.

What this part does
  • Provides cushioned support within the Targa mounting assembly
  • Helps isolate vibration between adjoining components
  • Reduces direct metal-to-metal contact
  • Helps control unwanted movement
  • Supports correct component positioning
  • Replaces aged, hardened or damaged original silentblocks
  • Suitable for Targa restoration and refurbishment
  • Supplied as an OE Match replacement part 

 Why Replace This Part? 
Silentblock bearings can deteriorate with age, repeated movement and environmental exposure. The resilient material may harden, crack, split or lose its ability to isolate movement effectively. A worn silentblock can contribute to:
  • Increased vibration
  • Excessive movement or play
  • Rattles or unwanted noise
  • Poor component alignment
  • Deteriorated mounting support

Replacing worn silentblocks helps restore proper support and isolation within the assembly.

When to Replace This Part
  • Silentblock is cracked or split
  • Material has hardened or deteriorated
  • Excessive movement is present
  • Targa assembly is being refurbished
  • Original mounting component is missing or damaged
  • Classic Porsche restoration work is being carried out

Where it fits on the car
Fits within the Targa mounting assembly, as shown under diagram reference 34.
