Diagram Ref No 2

The shock absorber is responsible for controlling compression and rebound as the suspension moves over bumps, dips and changing road surfaces. Its supporting mount keeps the damper correctly located while transferring suspension loads into the vehicle structure and helping isolate unwanted vibration.

Rear shock mounts experience constant loading during driving. Road impacts, cornering forces, vibration, temperature changes and general ageing can eventually cause the mount or its isolation material to deteriorate. Excessive wear may allow unwanted shock absorber movement, resulting in knocking noises and reduced suspension refinement.

This OE Match Rear Axle Shock Absorber Supporting Mount provides a high-quality replacement for a worn, cracked, loose or damaged original component.

What This Product Does:

• Secures the rear shock absorber to the vehicle structure.
• Maintains correct positioning of the shock absorber.
• Transfers suspension loads between the damper and chassis.
• Supports controlled compression and rebound movement.
• Helps isolate suspension vibration and harshness.
• Reduces unwanted movement at the shock absorber mounting point.
• Helps maintain consistent rear suspension behaviour.
• Supports predictable handling and chassis response.
• Works with the rear shock absorber and associated suspension components.
• Replaces a worn, deteriorated, loose or damaged mount.
• Provides an OE-style replacement for compatible Porsche applications.  

Symptoms Of Wear Or Failure:

• Knocking or clunking from the rear suspension.
• Rattling when driving over rough roads.
• Noise when travelling over bumps or potholes.
• Excessive movement at the shock absorber mounting point.
• Increased vibration transmitted into the cabin or body.
• Rear suspension that feels less controlled or settled.
• Abnormal movement of the shock absorber.
• Cracked or deteriorated rubber within the mount.
• Rubber separating from the surrounding mount structure.
• Visible distortion or physical damage.
• Corrosion affecting the mount or associated hardware.
• Loose mounting fasteners.
• Deterioration discovered while servicing or replacing the rear dampers.  

Why Replacement Matters:

• The shock absorber can only control suspension movement effectively when it is securely attached to the vehicle. A worn supporting mount may allow the damper to move at its mounting point instead of transferring suspension forces directly into the chassis as intended.
• This unwanted movement can produce knocking or rattling noises and reduce the precision of the suspension response. On a performance-oriented Porsche, even relatively small amounts of unwanted suspension movement can affect how consistent and composed the rear of the vehicle feels during cornering and directional changes.
• The mount also contributes to isolating vibration between the suspension and vehicle structure. As its rubber or isolation material deteriorates, additional vibration and harshness may be transmitted into the body.
• Continued use with a severely worn or damaged mount can place unnecessary loads on the shock absorber, mounting hardware and surrounding chassis attachment points.
• Replacing a deteriorated component with this OE Match Rear Axle Shock Absorber Supporting Mount helps restore secure damper location, reduce unwanted suspension movement and maintain controlled rear suspension behaviour.
