Diagram Ref No 8, 9, 10, 11, 12, 13
What This Product Does:
- The top mount (strut mount) sits between the top of the shock absorber/strut and the vehicle’s body/strut tower. It supports the loads from springs, damper, steering (via bearing), and absorbs vibration/road noise.
- A monoball mount version replaces the standard rubber mount with a spherical bearing (monoball) or very stiff mounting that provides more direct steering/suspension feedback, reduces deflection under load, and keeps suspension geometry (camber, caster) more consistent during hard cornering.
Symptoms & Signs You Need Replacement:
- Clunking or knocking noise from the top of the front strut tower when going over bumps or during steering inputs — a worn mount or bearing often causes this.
- Squeaking or creaking noise when steering the wheel, especially at low speeds — the strut mount bearing may be worn.
- Poor steering feedback or vague handling, especially when cornering hard — a worn mount can cause deflection and loss of camber control.
- Excessive vibration or noise through the body from the front suspension; worn mount rubber or bearing can transmit more noise.
- During a shock/strut replacement or front suspension overhaul — since the top mount assembly must be removed anyway, replacing the modern monoball upgrade kit is logical to restore or upgrade suspension quality.
- Steering geometry issues — if you’ve had camber/caster issues, or your tyres are wearing unevenly at the front, a poor top mount may contribute.
- Suspension performance & tyre contact: On high-performance cars like a Porsche 911 C4/Turbo, the front suspension’s geometry and mounting rigidity matter a lot. If the top mount is deflecting, you lose optimal tyre contact patch under load, which reduces grip, increases tyre wear, and impairs handling.
- Durability & noise/vibration: Rubber top mounts tend to degrade over time (cracking, flattening, absorbing road noise). A good mount + bearing kit eliminates unwanted compliance and noise, and lengthens life of the strut/damper assembly.
- Precise handling and steering feel: The top mount bearing allows the strut to turn with steering; if worn, you get sloppy steering feel and delayed response. Upgrading to a monoball mount helps sharpen the steering and gives more direct feedback.
- Prevents repeat labour: Since access to the strut top requires removing mount or taking down the strut, doing a mount/bearing replacement while everything is open is cost-effective. It avoids having to redo labour later when noise or wear returns.

Diagram Ref No 2, 3, 4, 5, 6, 8, 9, 10, 11
What This Product Does:
- The front strut (shock absorber) top mount is the connection point where the top of the suspension strut attaches to the car’s body (strut tower). It supports loads from the spring and damper, allows steering pivot (via bearing) and isolates the mount from road noise/ vibration.
- Inside that mount is a bearing to handle rotation as the front wheels steer, and various hardware/plates to secure the assembly.
- Over time, rubber mounts can deteriorate, bearings develop wear or play, mounting plates may corrode, dust covers degrade — this leads to noise (clunks, creaks), reduced ride comfort, compromised steering feel or alignment issues.
- The overhaul kit replaces the top mount, bearing and all associated supporting hardware so you restore that upper strut interface.
When You Should Consider Replacement:
- Clunking, creaking, or knocking noises from the front suspension, especially when turning or going over bumps, often signal worn mounts or bearings.
- If the steering feels vague, resists turning, or doesn’t return to center smoothly, the top mount bearing may be binding or worn.
- A degraded mount allows unwanted movement between the strut and body, resulting in increased harshness, poor damping response, or “floaty” handling.
- Always replace the top mount and bearing when fitting new front shocks or coilovers.
- These are wear-matched components, and reusing old mounts can undermine the benefits of new suspension.
Why Replacement Matters:
- Restores handling & ride quality: On a performance car like a Porsche, the front suspension’s mount integrity is critical. A worn mount allows movement under load, reducing handling precision, altering tyre contact patches or upset steering response.
- Eliminates noise & NVH issues: A degraded top mount/bearing often causes unpleasant noises from the front suspension — creaks when turning the wheel, clunks over bumps, rattles from the top mount. Replacing rectifies the source.
- Pre-emptive maintenance saves cost: Since the front strut top mount is only easily accessed when removing the strut assembly or front tower, replacing the full mount kit while you’re working in that area is far more efficient than doing parts piecemeal later.
- Prevents escalation of damage: A failing top mount could lead to bearing failure, strut shaft wear, mount plate fatigue or body mount damage — addressing the mount prevents cascading failures.

Diagram Ref No 8, 9, 10, 11, 12, 13
What This Product Does:
- The strut mount (top mount) is the structural connection point between the top of the front shock/strut assembly and the car’s body (strut tower). It absorbs loads from the suspension (spring & damper) and allows the strut to pivot (for steering) via the bearing.
- The contact bearing or pivot bearing allows the front strut to rotate as the wheels are steered while maintaining smooth operation and minimal noise/fretting.
- Over time, the mount’s rubber cushion, metal plates or bearing can degrade, leading to noise, poor alignment, or less effective suspension function. The kit restores correct mount geometry, alignment, reduces unwanted movement, and improves ride/handling feel.
Symptoms & Signs You Need Replacement:
- Clunking or knocking noise from the top of the front strut tower when going over bumps or during braking/acceleration.
- Squeaking or groaning noise when turning the steering wheel – could indicate the bearing is worn.
- Excessive vibration or harshness coming through the body when driving, indicating the mount rubber may be fatigued.
- Uneven tyre wear or vague steering feel – if the strut mount is worn, the strut top may move under load, affecting geometry.
- During shock/strut replacement – because the mount is accessed when replacing the front shocks, it is wise to replace the mount/bearing at the same time to avoid future failure.
- Safety & handling: The strut mount plays a key role in the front suspension’s operation. A worn mount can compromise handling precision, ride comfort and may allow excessive movement under load.
- Noise, vibration & harshness: A deteriorated mount/bearing leads to unwanted noise and vibrations that degrade driving experience.
- Longevity of other components: If the mount is worn, the bearing, strut rod, or strut top plate may be overloaded, leading to premature failure of those parts. Replacing now can prevent larger issues.
- Cost-effective during service: Because the mount/bearing sits atop the strut, it typically requires partial suspension disassembly to reach. Replacing during suspension service is more economical than later doing mounts alone.

This is for the shock absorber as an additional spring, also known as a bump stop, stopper or helper spring, designed for the front strut assemblies on Porsche 997 models equipped with the Sport chassis (option codes I030 or I480). Front axle suspension assembly for Porsche 996/997 (1998–2012), serving as a rubber stop or bushing integrated into the strut structure.
Fits:
Porsche 997 C2 / C2S / C4 / C4S MKI 2005-08 - Cars with SPORT chassis (Option code: I030/I480)
Porsche 997 C2 / C2S / C4 / C4S MKII 2009-12 - Cars with SPORT chassis (Option code: I030)
Porsche 996 C2 / C2S / C4 / C4S - Cars with SPORT chassis (Option code: IX74 / M030)
This acts as a progressive load-bearing element, cushioning the suspension when the strut nears full compression. It helps prevent harsh bottoming-out, protecting both the strut and chassis from damage during aggressive driving or over bumps.
These components maintain ride quality and handling performance, especially under heavy loading or spirited cornering, keeping the suspension linear and controlled.
Common Issues & Considerations
Wear or Deterioration: Over time, the rubber can compress, crack, or lose elasticity, diminishing its effectiveness. This can lead to harsher suspension impacts at full compression.
Noise or Harsh Feedback: A worn or hardened bump stop can transmit noise or impacts through the cabin, particularly over rough roads or speed bumps.
Sport vs. Standard Suspension: These parts are specific to Sport chassis models. Non-sport setups may not have the same bump stops or use different part numbers, so swapping or replacing must be done accordingly.

Front axle suspension assembly for Porsche 996/997 (1998–2012), serving as a rubber stop or bushing integrated into the strut structure.
Fits:
Porsche 997 C2 / C2S / C4 / C4S MKI 2005-08 - Cars with SPORT chassis (Option code: I030/I480)
Porsche 997 C2 / C2S / C4 / C4S MKII 2009-12 - Cars with SPORT chassis (Option code: I030)
Porsche 996 C2 / C2S / C4 / C4S - Cars with SPORT chassis (Option code: IX74 / M030)
This acts as a progressive load-bearing element, cushioning the suspension when the strut nears full compression. It helps prevent harsh bottoming-out, protecting both the strut and chassis from damage during aggressive driving or over bumps.
These components maintain ride quality and handling performance, especially under heavy loading or spirited cornering, keeping the suspension linear and controlled.
Common Issues & Considerations
Wear or Deterioration: Over time, the rubber can compress, crack, or lose elasticity, diminishing its effectiveness. This can lead to harsher suspension impacts at full compression.
Noise or Harsh Feedback: A worn or hardened bump stop can transmit noise or impacts through the cabin, particularly over rough roads or speed bumps.
Sport vs. Standard Suspension: These parts are specific to Sport chassis models. Non-sport setups may not have the same bump stops or use different part numbers, so swapping or replacing must be done accordingly.

• Position on Vehicle: Mounted at the top of the front suspension strut/damper assembly, under the front sub-frame, where it supports angular movement and load transfer through the bearing above the strut.
• Cross-Reference / Alternative Numbers: OEM number: 996 343 501 00 (sometimes shown as 99634350100)
• Applications: Replacement when the original front strut bearing shows signs of wear such as noise, binding, or play - restoring correct suspension articulation, reducing noise and preserving handling response.
The front strut top bearing is a key element in the suspension system - linking the strut to the chassis and allowing smooth turning and suspension travel. When the bearing becomes worn, loose or corroded, you may experience clunks, steering noise, compromised alignment or uneven tyre wear. Replacing it with a high-quality OE-Match unit restores silent, precise suspension behaviour and maintains the sophisticated ride and handling that Porsche drivers expect.
When and why to replace:
• Noticeable noise (clunking, groaning) when steering or traversing bumps through the front suspension.
• Excessive play or roughness at the top of the strut when the bonnet is open or during suspension movement.
• Uneven tyre wear or alignment issues traceable to front suspension bearing play.
• After front-end suspension work or damper/strut replacement - when access is available.
• High-mileage vehicle or original bearing installed long ago and potentially at end-of-life.

Why are important / when to replace
Correct ride height & geometry: Porsche marks springs with tolerance codes; the correct compensating plate thickness is used to achieve the intended static height and suspension geometry. Using the wrong thickness (or missing the plate) can shift ride height by a few millimeters and slightly alter camber/handling.
Proper spring seating: the plate centers and supports the spring top so the spring doesn’t “walk” or sit unevenly on the top mount — missing/damaged plates can allow the spring to sit off-centre and introduce noise or uneven wear.
During any strut/spring/top-mount job: always inspect/replace these plates when you disassemble the strut. They’re inexpensive and commonly replaced as part of a suspension refresh.
Common issues and symptoms
Clunking or popping noises over bumps or in turns if the spring isn’t seating properly (plate missing, crushed, corroded or installed with wrong orientation).
Incorrect ride height / slight handling changes if the wrong thickness is used (3.0 mm vs 6.5 mm can change static height and the intended spring preload/stack). Enthusiast threads explicitly call out these two thicknesses and their effect.
Corrosion / physical damage: over time OE plates can corrode or get deformed during disassembly — they’re cheap and often replaced because removal can damage them.
