Clutch Power Spring. Porsche 986 Boxster 1997–04  ›  98642308112

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

Fits:

• Porsche Boxster 986 2.5L 1997-99
• Porsche Boxster 986 2.7L 1999-02
• Porsche Boxster S 986 3.2L 1999-02
• Porsche Boxster 986 2.7L 2003-04
• Porsche Boxster S 986 3.2L 2003-04  

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.
