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.

Correct flywheel bolts are critical because they maintain the integrity of the crank-to-flywheel joint - supporting smooth power transfer, stable clutch operation, and long-term reliability. This OE Match version is designed for direct replacement during clutch/flywheel service and engine rebuild work.
Function: These bolts thread into the crankshaft flange and clamp the flywheel in place, ensuring accurate alignment and a secure interface between engine and clutch assembly. Proper bolt specification supports consistent torque retention and helps protect the flywheel, crank flange, and clutch components from vibration-related wear.
Flywheel bolts operate under high stress and can fatigue, stretch, or lose torque retention after removal and re-torque cycles. Replacing them with correct OE Match bolts helps ensure proper clamp load, reduces the risk of loosening, and protects expensive components from damage caused by flywheel movement.
When to replace:
• During clutch replacement or flywheel removal
• During engine rebuilds or rear main seal work requiring flywheel removal
• If bolts show thread damage, corrosion, or signs of stretching
• When service procedure specifies new bolts on reassembly
• Any time correct torque cannot be reliably achieved
