Manufactured from high-strength steel with a precision-wound inner cable and a durable, flexible outer sheath, the cable is engineered to resist wear, vibration and corrosion while maintaining smooth operation over its full 2750mm length. It provides factory-style fitment and is ideal for restoring accurate vehicle speed readings during repairs or restoration projects.

What This Product Does:

• Transmits rotational drive from the gearbox to the mechanical speedometer.
• Provides accurate vehicle speed readings.
• Includes both the inner cable and outer protective casing.
• Ensures smooth, low-friction operation of the speedometer.
• Maintains reliable communication between the transmission and instrument cluster.
• Helps preserve accurate mileage recording on mechanical systems.
• Restores factory-style operation of the speedometer.
• Forms an essential part of the vehicle's mechanical speedometer system.

Symptoms Of Wear Or Failure:

• Speedometer needle fluctuating or bouncing.
• Complete loss of speedometer operation.
• Clicking, squealing or whining noises behind the dashboard.
• Intermittent speed readings.
• Stiff or seized cable movement.
• Broken inner drive cable.
• Damaged or split outer cable casing.
• Inaccurate vehicle speed indication.
• Odometer failing to record mileage correctly (where mechanically driven).
• Visible corrosion or wear on the cable assembly.

Why Replacement Matters:

• The speedometer cable operates continuously while the vehicle is moving and is subjected to constant rotation, vibration and environmental exposure. Over time, the inner cable can wear, stretch or break, while the outer casing may crack or allow moisture and dirt to enter, increasing friction and accelerating wear.
• A faulty speedometer cable can lead to inaccurate speed readings, erratic needle movement or complete loss of speedometer and odometer function. This can affect driver awareness, vehicle legality and the accuracy of recorded mileage.
• Replacing the complete inner and outer cable assembly restores smooth, accurate speedometer operation and dependable performance. The OE Match replacement provides factory-correct length, precise fitment and durable construction, helping preserve the authenticity, functionality and driving experience of your classic Porsche.
