Product Information
Silentblock bearing with pin for Targa roof
The Genuine Porsche Silentblock Bearing (Part Numbers: 91156503742 / 91156503842) is an original equipment Targa roof mounting component designed for classic Porsche 911 and 964 Targa models. Also known as a Targa roof locating pin or bonded rubber mounting, this component forms part of the rear Targa roof mounting assembly, helping locate and support the removable roof panel in its correct position. Featuring a rubber-bonded construction, the Silentblock bearing helps absorb vibration and minimise unwanted movement between the roof panel and its mounting points.

Fits:
Porsche 911 1974 - 1989 TARGA
Porsche 964 1989 - 1994 TARGA

Diagram ref no 34

Manufactured to Porsche's original specifications, it provides precise fitment and reliable support, making it an ideal replacement for worn or damaged original mountings during Targa roof repairs, maintenance or classic Porsche restoration.

What Does This Part Do? – Functions
  • Secure Roof Positioning: Helps locate and support the rear section of the Targa roof panel.
  • Vibration Absorption: Reduces vibration transmitted through the roof mounting assembly.
  • Roof Alignment: Helps maintain correct positioning of the removable roof.
  • Reduced Movement: Minimises unwanted movement and potential rattling.
  • Original Fitment: Maintains factory-correct Targa roof mounting specifications.

Why Replace This Part?
Over time, the Silentblock bearing can deteriorate due to ageing, repeated roof removal, vibration and exposure to environmental conditions. The rubber mounting may harden, crack or lose its ability to support the roof correctly. A worn or damaged bearing may contribute to roof movement, rattling noises or incorrect panel alignment.

Replacing it with a genuine Porsche component helps restore secure roof positioning, reduce vibration and maintain the original functionality of the Targa roof assembly.

When to Replace This Part?
Rubber Deterioration: Cracked, hardened or perished rubber mounting.
Loose Roof Fitment: Excessive movement in the removable roof panel.
Rattling Noises: Unwanted vibration or noise from the roof assembly.
Damaged Locating Pin: Bent, worn or damaged mounting component.
Roof Misalignment: Incorrect seating of the rear Targa roof section.
Restoration Work: During Targa roof frame repairs or replacement.

Where Does It Fit on the Car?
Location: Targa roof – rear roof frame mounting assembly.

The Silentblock bearing is fitted at the rear mounting points of the removable Targa roof panel. It incorporates a locating pin that helps position the rear section of the roof correctly when installed on the vehicle.

Separate left-hand and right-hand versions are available to suit the corresponding roof mounting positions.
