Shock Absorber Supporting Mount, FRONT.

Restore secure shock absorber location, controlled suspension movement and dependable front-end performance with this OE Match Front Shock Absorber Supporting Mount. Designed for compatible Porsche applications, this mount forms an important connection between the front shock absorber assembly and the vehicle body or chassis.

Diagram Ref No 3

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

Front shock absorber mounts are continually subjected to road impacts, steering and cornering forces, vibration and repeated suspension movement. Over time, rubber isolation material and other parts of the mount can deteriorate, crack, deform or develop excessive play.

This OE Match Front Shock Absorber Supporting Mount provides a high-quality replacement for a worn, loose or damaged original component, helping restore correct damper support and predictable suspension behaviour.

What This Product Does:

• Secures and supports the front shock absorber assembly.
• Maintains correct positioning of the damper relative to the vehicle.
• Transfers suspension forces between the shock absorber and chassis.
• Supports controlled suspension compression and rebound.
• Helps isolate vibration and road harshness from the vehicle body.
• Reduces unwanted movement at the shock absorber mounting point.
• Helps maintain consistent front suspension behaviour.
• Supports predictable handling and vehicle stability.
• Works with the shock absorber and associated front suspension components.
• Replaces a worn, cracked, loose or damaged supporting mount.
• Provides an OE-style replacement for compatible Porsche applications.  

Symptoms Of Wear Or Failure:

• Knocking or clunking from the front suspension.
• Rattling when travelling over rough roads.
• Noise when driving over bumps or potholes.
• Excessive movement at the shock absorber mounting point.
• Increased vibration or harshness transmitted into the body.
• Front suspension that feels loose or less controlled.
• Changes in steering or handling feel.
• Abnormal movement within the shock absorber assembly.
• Visible cracking or deterioration of rubber components.
• Rubber separating from the mount structure.
• Distortion or physical damage to the mount.
• Corrosion around the mount or associated hardware.
• Loose or damaged mounting fasteners.
• Deterioration discovered while replacing the front shock absorbers.  

Why Replacement Matters:

• The shock absorber can only control suspension movement effectively when it is securely attached to the vehicle. If its supporting mount becomes worn or develops excessive play, some suspension movement can occur at the mounting point instead of being properly controlled by the damper.
• This unwanted movement may produce knocking or rattling noises and can reduce the precision of the front suspension. On a performance vehicle, deterioration within a suspension mounting point can affect steering response and the consistency of the chassis during cornering and braking.
• The mount also helps isolate vibration between the suspension and vehicle structure. As the isolation material deteriorates, additional road noise, vibration and harshness may be transmitted into the cabin.
• Severe deterioration can also place additional stress on the shock absorber, mounting hardware and surrounding chassis attachment points.
• Replacing a worn or damaged component with this OE Match Front Shock Absorber Supporting Mount helps restore secure damper location, reduce unwanted suspension movement and maintain predictable front-end behaviour.

What This Product Does

The additional springs, commonly described as bump stops, provide progressive cushioning as the suspension approaches the end of its compression travel. The bellows cover the exposed shock absorber piston rods, helping to limit contact with road dirt and other contamination. Together, these parts support correct shock absorber operation and are suitable for installation during front suspension servicing.

Functions

• Cushions the final stage of front suspension compression
• Helps prevent harsh metal-to-metal bottoming
• Protects the shock absorber piston rod from road contamination
• Supports controlled movement of the front strut assembly
• Replaces deteriorated, split or compressed original components
• Allows both front suspension struts to be serviced together

Technical Details

• Position: Front axle
• Quantity: SET OF 4
• Contents: two additional springs and two shock absorber bellows
• Additional spring reference: 99634330102
• Bellows reference: 99634350500
• Exploded diagram reference numbers: 8 and 9

Symptoms of Fault

• Harsh impacts when the suspension is heavily compressed
• Knocking or increased noise over uneven surfaces
• Split, crumbling or permanently compressed bump stops
• Torn or detached shock absorber dust covers
• Visible dirt or contamination around the shock absorber piston rod
• Poorly controlled suspension travel when encountering larger bumps

Why Replacement Matters

Bump stops and bellows deteriorate through age, repeated compression, heat, moisture and road contamination. Worn components can reduce protection for the shock absorber and allow harsher suspension compression. Replacing them while the front struts are dismantled avoids reusing perished parts and can reduce the need to repeat the same labour later. OE Match components are intended as OE-equivalent replacements for routine suspension maintenance.

OE Reference

• 99634330102 — shock absorber additional spring
• 99634350500 — shock absorber bellows

FAQs

• Does this kit service both front struts?
  Yes. The SET OF 4 contains two additional springs and two bellows for the left and right front shock absorber assemblies.
• Should these parts be renewed with new shock absorbers?
  Replacement is advisable when the existing parts are split, compressed, damaged or perished, particularly while the struts are already dismantled.
• Is wheel alignment required afterwards?
  An alignment check is generally recommended following significant suspension work or if the vehicle shows uneven tyre wear or altered steering behaviour.
