What This Part Does / Functions:
• Fits within the front air suspension shock absorber / strut assembly
• Helps cushion the suspension as the strut compresses
• Assists in controlling suspension movement at the end of travel
• Helps protect the shock absorber and air suspension components from harsh compression impacts
• Supports correct front suspension operation on air suspension models
• Helps reduce knocking, harshness or impact feel from worn strut bumper components
• Maintains OE Porsche suspension fitment and factory ride quality.

Why Replace This Part?
The helper spring / strut bumper is exposed to suspension movement, road shock, temperature changes and age. Over time, it can compress, split, crumble, harden or become damaged. A worn helper spring may reduce bump-stop cushioning and can contribute to harsh suspension feel, noise or poor strut protection. Replacing it with a Genuine Porsche OE helper spring helps restore the correct cushioning function within the front air suspension strut assembly and supports the original suspension design.

When to Replace This Part
•  If the helper spring / strut bumper is cracked, split or deteriorated
•  If the front suspension feels harsh over bumps
•  If there is knocking or impact noise from the front strut area
•  During front shock absorber or air suspension strut replacement
•  When rebuilding or servicing the front air suspension strut assembly
•  If the original rubber/foam component is crumbling or compressed
•  When restoring the suspension with correct OE Porsche components.

Where It Fits on the Car
This part fits on the front axle, within the front shock absorber / suspension strut assembly on Porsche Panamera models with air suspension. It is used on the front left or front right strut, depending on the repair being carried out.

Installed as part of the front air suspension assembly, the helper spring assists the air spring and shock absorber by supporting suspension loads during changes in ride height and suspension travel. Constructed from high-strength spring steel and engineered to withstand continual compression and extension cycles, it contributes to smooth suspension operation and enhanced ride comfort.  

What This Product Does:

• Provides supplementary support to the front air suspension assembly.
• Assists in maintaining correct ride height.
• Supports suspension movement throughout its travel range.
• Helps reduce load on the air spring system.
• Contributes to ride comfort and suspension stability.
• Maintains proper suspension geometry and wheel control.
• Supports vehicle handling during braking and cornering.
• Enhances overall air suspension performance and reliability.

Symptoms Of Wear Or Failure:

• Uneven front ride height.
• Sagging suspension on one side of the vehicle.
• Reduced ride comfort.
• Excessive suspension movement.
• Clunking or rattling noises from the suspension assembly.
• Increased load on air suspension components.
• Poor vehicle stability during cornering or braking.
• Visible corrosion, cracking or damage to the spring.
• Suspension warning messages in severe cases.
• Premature wear of associated suspension components.

Why Replacement Matters:

• Helper springs operate under constant load and are exposed to road debris, moisture, temperature fluctuations and repeated suspension cycling. Over time, the spring can weaken, corrode or sustain physical damage, reducing its ability to properly support the suspension system.
• A worn helper spring can place additional strain on the air suspension assembly, affecting ride quality, handling characteristics and suspension durability. If left unresolved, excessive loading may accelerate wear of air springs, shock absorbers and suspension mounts, potentially leading to costly repairs.
• Replacing a worn or damaged helper spring restores proper suspension support, helps maintain correct ride height and ensures the air suspension system operates as intended. An OE Match replacement provides factory-style fitment, durable construction and dependable long-term performance, helping preserve the comfort, stability and refined driving experience expected from your Porsche.
