This OE Match flywheel gland nut is produced to OE-equivalent standards, replicating the original Porsche part’s dimensions, materials, and performance characteristics. Made from high-strength steel with suitable surface treatment, it delivers the necessary tensile strength and thread integrity required in high-stress crankshaft/flywheel applications.

The gland nut plays a critical role in securing the engine flywheel, which transmits engine torque to the clutch and drivetrain. A properly torqued gland nut prevents loosening, shearing, or axial creep under varying engine speeds and loads. Over time, original nuts can become fatigued, corroded, or damaged - especially after flywheel removal during clutch or engine service. Replacing worn or suspect hardware with this OE Match gland nut restores correct flywheel retention, improves service reliability, and ensures that the flywheel remains securely seated on the crankshaft flange.

This part installs directly with the original flywheel and crankshaft threads, making it ideal for clutch jobs, engine rebuilds, or preventative drivetrain maintenance.

The flywheel gland nut clamps and secures the engine flywheel to the crankshaft flange, ensuring a secure interface that transmits engine torque through the clutch assembly to the transmission. It withstands rotational and vibrational loads, preventing movement that could lead to driveline issues.
