Engineered from high-grade materials and designed to withstand the extreme loads, vibration and temperature variations generated within the drivetrain, the clutch bolt provides the clamping force required to keep clutch components securely fixed during operation. Accurate fitment and correct torque are essential for reliable clutch performance and long-term drivetrain durability.
What This Product Does:
- Secures clutch assembly components to the flywheel or mounting surface.
- Maintains critical clamping force within the clutch system.
- Helps ensure correct alignment of clutch components.
- Withstands high rotational forces and drivetrain loads.
- Supports safe and reliable clutch operation.
- Prevents unwanted movement of clutch components.
- Contributes to overall drivetrain reliability and performance.
Symptoms Of Wear Or Failure:
- Loose clutch assembly components.
- Vibration from the clutch or drivetrain.
- Unusual noises from the bellhousing area.
- Clutch engagement irregularities.
- Visible corrosion, thread damage or bolt stretching.
- Difficulty maintaining correct torque specification.
- Premature wear of clutch or flywheel components.
- Clutch assembly movement under load.
- Potential drivetrain damage in severe cases.
Why Replacement Matters:
- Clutch bolts are subjected to extreme mechanical loads, rotational forces, heat cycles and vibration throughout their service life. Many clutch bolts are torque-to-yield fasteners and are designed for single-use applications. Reusing worn or stretched bolts can compromise clamping force and increase the risk of component loosening.
- A failed or improperly secured clutch bolt can lead to clutch misalignment, vibration, drivetrain damage and, in severe cases, catastrophic clutch assembly failure. During clutch replacement or transmission service, installing new clutch bolts is essential to ensure the correct clamping force and long-term reliability of the assembly.
- Replacing clutch bolts with OE Match components restores factory-specified fastening performance, maintains clutch system integrity and helps protect surrounding drivetrain components. OE Match replacement bolts provide factory-style fitment, precise manufacturing and dependable strength, ensuring reliable operation and long-term durability for your Porsche.

The clutch bolt provides the clamping force that holds the clutch assembly together. By fastening the pressure plate to the flywheel at precise torque settings, it enables reliable torque transfer between the engine and transmission. Proper fasteners are essential for consistent clutch engagement, smooth shifting, and long-term drivetrain durability.
Need 9 per car. Price is for each.

Installed through the clutch pressure plate into the flywheel, this bolt spreads load evenly and resists loosening under vibration and torque. Its material and geometry are matched to the factory specification so that it maintains clamping force throughout heat cycles and driving loads, helping prevent premature wear and ensuring stable clutch diaphragm performance.
Clutch bolts are subject to high clamping forces, heat cycles, and torque loads. Over time, original hardware can stretch, corrode, or fatigue, all of which can lead to compromised load retention. Reusing old or damaged fasteners increases the risk of clutch slip, uneven pressure plate contact, or flange failure. Installing fresh bolts helps restore correct clamping integrity and reduces the risk of future clutch-related issues.
When to replace:
• During clutch replacement or overhaul
• If original bolts show corrosion, stripping, or rounding
• After removal during transmission service
• Preventive maintenance in performance or high-mileage vehicles

Provides the critical clamping force between crankshaft flange and flywheel. Correct bolt stretch and friction are essential to prevent loosening, fretting, or flywheel run-out that can cause vibration, starter engagement issues, or clutch damage.
Over time, flywheel bolts can stretch, corrode, or lose their clamping strength due to repeated torque cycles and heat exposure. A weakened or reused bolt may fail to maintain the necessary preload, risking vibration, misalignment, or flywheel damage.
Replace the flywheel bolts when:
• Performing a clutch or flywheel replacement (most Porsche bolts are single-use torque-to-yield).
• Bolts show signs of corrosion, thread damage, or head wear.
• The factory service procedure specifies new bolts for reassembly.
Installing a new bolt set ensures secure fastening, correct torque tension, and long-term drivetrain reliability.
