The Genuine Porsche Clutch Power Spring is a replacement clutch pedal assistance spring designed for early Porsche Boxster 986 manual-transmission models.

Diagram Ref No 9
Installed within the driver-side pedal assembly, the spring assists the movement of the clutch pedal as it is pressed and released. It helps provide the characteristic factory pedal effort and contributes to smooth, consistent clutch pedal operation.
The component is sometimes referred to as a clutch pedal power spring, servo spring, boost spring or clutch assist spring. It is part of the pedal mechanism rather than the clutch assembly inside the transmission bellhousing.
Over time, the spring and its associated mounting points can wear, become noisy, lose tension or suffer mechanical damage. A faulty power spring can make the clutch pedal feel heavier, inconsistent or rough and may cause squeaking or scraping noises during pedal movement.
What This Product Does:
The clutch power spring assists movement of the clutch pedal throughout its operating range.
It is designed to:
- Assist clutch pedal movement.
- Help reduce excessive pedal effort.
- Provide the intended factory clutch pedal feel.
- Support smooth pedal travel.
- Assist the pedal during clutch engagement and disengagement.
- Help the pedal return predictably.
- Work with the clutch pedal and hydraulic clutch-control system.
- Replace a worn, noisy, damaged or missing original spring.
- Maintain consistent clutch control during normal driving.
The spring does not operate the clutch by itself. The driver still moves the clutch pedal, which operates the clutch master cylinder and hydraulic release system. The power spring modifies and assists the force required at the pedal.
Symptoms Of Wear Or Failure:
Possible symptoms include:
- Clutch pedal feeling unusually heavy.
- Pedal effort changing through its travel.
- Clutch pedal feeling inconsistent.
- Squeaking when pressing or releasing the pedal.
- Scraping noises from the pedal area.
- Clicking or creaking from the driver footwell.
- Pedal movement becoming rough or notchy.
- Pedal returning less smoothly than normal.
- Excessive free movement around the spring mechanism.
- Spring visibly cracked or broken.
- Spring becoming detached from its mounting.
- Damage to the spring casing or mounting points.
- Clutch pedal feel changing suddenly.
- Pedal requiring greater effort than previously.
Similar symptoms can also be caused by the clutch master cylinder, pedal bushes, hydraulic system or clutch release components, so the complete clutch-control system should be inspected.
Why Replacement Matters:
The power spring contributes directly to clutch pedal feel and driver control.
A worn or broken spring may increase pedal effort or make the pedal movement inconsistent, particularly during repeated clutch operation in traffic.
Replacing a defective spring helps restore:
- Correct clutch pedal assistance.
- More consistent pedal effort.
- Smoother clutch operation.
- Predictable pedal return.
- Reduced pedal-area noise.
- Factory-style clutch pedal feel.
- Easier clutch modulation.

Porsche Clutch Pedal & Parts | Design911 Performance Pedal Systems for Precision Shifting
The clutch pedal plays a critical role in the performance and drivability of every Porsche, managing the connection between the engine and transmission. Whether in a classic air-cooled model or a modern sports car, precise clutch pedal control ensures smooth gear changes, predictable engagement, and ultimate driver confidence. Over time, clutch pedal components can wear or degrade, affecting shift quality and overall vehicle performance.
At Design911, we offer a comprehensive selection of clutch pedals, brackets, springs, shafts, and bush kits engineered for performance and durability. Each component is designed for accurate fitment, smooth operation, and long service life — making them perfect for restorations, performance upgrades, or track-prepared vehicles.
What Does the Clutch Pedal Do?
The clutch pedal controls the engagement and disengagement of power between the engine and gearbox. It allows drivers to change gears smoothly while maintaining full control over torque delivery.
Core Functions:
• Disengages the clutch to enable smooth gear shifts.
• Provides precise modulation of clutch engagement for performance driving.
• Links to master cylinders, cables, and hydraulic systems.
• Delivers consistent pedal feel for both road and track use.
• Ensures accurate clutch control for optimum driveline performance.
A well-functioning clutch pedal system is key to achieving seamless shifting and responsive power transfer — essential for spirited Porsche driving.
Why Do Clutch Pedals & Components Fail?
Clutch pedal assemblies endure continuous stress from hydraulic pressure, heat, and mechanical movement. Over time, wear or corrosion can lead to poor engagement and inconsistent pedal feel.
Common Causes of Failure Include:
• Worn pedal bushings or pivot points causing excess play.
• Broken or fatigued return springs.
• Cracks or bending in the pedal arm or mounting bracket.
• Leaking or seized linkage components.
• Corrosion or metal fatigue from age and repeated use.
Failure in any of these components can lead to stiff, noisy, or unresponsive clutch action — reducing performance and driving enjoyment. Why Replace or Upgrade Your Porsche Clutch Pedal?
Replacing worn clutch pedal components restores smooth operation, precise feel, and safe engagement. Upgraded materials and improved designs also enhance reliability under demanding driving conditions.
Key Benefits:
• Restores proper clutch engagement and pedal feel.
• Improves shifting accuracy and response.
• Eliminates squeaks, stiffness, or excessive pedal travel.
• Constructed from high-strength steel or billet aluminium for durability.
• Fits Porsche 911, Boxster, Cayman, 944, and 968 models.
• Ideal for restoration, motorsport, and high-performance builds.
Design911’s Porsche clutch pedal assemblies and
components deliver precision-engineered performance for drivers who demand
the perfect connection between gearbox and engine.
Highlights
