Why Replace This Part?
Connecting rod bolts are critical engine fasteners. They are exposed to extreme tensile loads, high engine speed, heat cycles and repeated combustion forces. During engine repair or rebuild, con rod bolts are commonly replaced rather than reused, especially where Porsche workshop procedures specify renewal after removal.

Using the correct Genuine Porsche connecting rod bolt helps ensure the connecting rod assembly is clamped to the correct factory specification.

When to Replace This Part
•   Whenever the connecting rod cap is removed, if Porsche procedure specifies bolt renewal
•   During connecting rod bearing replacement
•   During full engine rebuild
•   If the bolt shows signs of stretching, corrosion or thread damage
•   If the bolt has been over-torqued or incorrectly fitted
•   When replacing connecting rods or crankshaft components.

Where It Fits on the Car
This bolt fits inside the engine crankshaft / connecting rod assembly. It secures the connecting rod cap around the crankshaft journal and forms part of the engine’s rotating assembly. Correct installation is essential.

Always follow Porsche workshop procedures, tightening sequence, torque settings and angle specifications.
