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.

Constructed from durable metal and bonded rubber components, the mount absorbs suspension loads while allowing controlled movement of the shock absorber during operation. It serves as the primary connection point between the suspension strut assembly and the chassis, helping to maintain proper suspension geometry and vehicle handling characteristics.
What This Product Does:
- Secures the front shock absorber assembly to the chassis.
- Supports suspension loads during driving.
- Absorbs and isolates noise, vibration and harshness (NVH).
- Maintains correct suspension alignment and geometry.
- Allows controlled movement of the suspension assembly.
- Contributes to precise steering response and vehicle handling.
- Helps protect surrounding suspension components from excessive stress
- Supports ride comfort and driving stability.
Symptoms Of Wear Or Failure:
- Clunking or knocking noises from the front suspension.
- Excessive vibration transmitted into the cabin.
- Poor ride quality or harsh suspension operation.
- Wandering or instability during driving.
- Reduced steering precision.
- Uneven tyre wear.
- Visible cracking or separation of the rubber mount.
- Excessive movement within the suspension assembly.
- Misalignment of suspension components.
- Premature wear of shock absorbers and associated parts.
Why Replacement Matters:
- Front shock absorber supporting mounts are subjected to constant suspension movement, road impacts, cornering forces and environmental exposure. Over time, the rubber isolator can deteriorate, crack or separate from its housing, while the mount itself may suffer from fatigue and wear.
- A worn supporting mount can negatively affect suspension performance, steering accuracy and ride comfort. Excessive movement within the mount can place additional strain on shock absorbers, springs and steering components, potentially leading to accelerated wear and costly repairs.
- Replacing a worn or damaged shock absorber supporting mount restores proper suspension support, improves ride quality and maintains precise vehicle handling. An OE Match replacement provides factory-style fitment, dependable vibration isolation and long-lasting durability, helping preserve the comfort, safety and performance characteristics expected from your Porsche.

It provides a cushioning effect when the suspension approaches the end of its travel, helping protect the shock absorber and surrounding components from damage.
What Does It Do?
The bump stop cushions the suspension during heavy compression, reducing the risk of the shock absorber reaching the end of its travel abruptly.
Why Does It Fail?
Common causes include:
- Age-related material deterioration
- Repeated suspension compression
- Exposure to road dirt and moisture
- Cracking or splitting
- Damage during shock absorber removal
When Should It Be Replaced?
Replace if the bump stop is cracked, crumbling, compressed or missing.
Inspection is recommended when replacing shock absorbers, springs or other suspension components.
Checks & Diagnosis
Inspect the bump stop for visible deterioration and check the shock absorber for leaks or damage.
Harsh impacts over bumps or excessive suspension bottoming may indicate worn suspension components requiring investigation.
Key Features
- OE Match replacement shock absorber bump stop
- Suitable for applicable Porsche 964 and 993 models
- Cushions excessive suspension compression
- Helps protect shock absorbers from damage
- Ideal for suspension servicing and restoration
Porsche 964 & 993 Shock Absorber Bump Stops and Suspension Parts
Shock absorber bump stops are important components of the Porsche 964 and 993 suspension systems, helping control suspension travel and protect shock absorbers during heavy compression.
Replacing deteriorated bump stops helps maintain suspension protection and supports reliable operation.
