Over time, the original plastic odometer gears become brittle due to age and prolonged exposure to heat, eventually cracking, losing teeth, or failing completely. This commonly results in the odometer and trip meter ceasing to function while the speedometer continues to display vehicle speed correctly. Replacing worn gears restores accurate mileage recording and preserves the originality and functionality of the instrument cluster. These OE Match gears are ideal for routine maintenance, speedometer repairs, and Porsche restoration projects.  

What This Product Does:

• Drive the odometer and trip meter mechanisms.
• Transfer rotational movement within the speedometer assembly.
• Restore accurate mileage recording.
• Available in 15-tooth, 20-tooth, and 25-tooth versions for compatible applications.
• Replace cracked, worn, or broken original gears.
• Improve the reliability of the instrument cluster.
• Provide an OE-style fit and dependable quality.

Symptoms Of Wear Or Failure:

• Odometer no longer records mileage.
• Trip meter fails to advance correctly.
• Speedometer operates but the odometer does not.
• Cracked, broken, or missing gear teeth.
• Intermittent mileage recording.
• Internal gear damage discovered during instrument refurbishment.
• Instrument cluster restoration requiring replacement drive gears.

Why Replacement Matters:

• The odometer speedometer gears are essential internal components that transfer the rotational drive required to operate the odometer and trip meter accurately. As the original plastic gears age, they commonly become brittle and fracture, causing the mileage recording mechanism to stop even though the speedometer itself continues to function normally.
• Replacing the worn gears restores accurate odometer and trip meter operation, preserving both the functionality and value of the vehicle while maintaining the originality of the instrument cluster. Manufactured as a direct replacement and produced to OE-style specifications, these OE Match odometer speedometer gears provide the correct fit, dependable quality, and long-lasting durability, making them an excellent choice for Porsche maintenance, instrument repairs, and restoration projects.
