Speedo Driven Gear GM 36-Tooth Natural

The Speedo Driven Gear GM 36-Tooth Natural from TCI is a precision speedometer drive component engineered for General Motors vehicles undergoing transmission swaps, gear ratio changes, or custom driveline builds. This component is essential for maintaining accurate speed readouts despite modifications to rear axle ratios or gear sets.

As the driven gear in the speedometer calibration system, the 36-tooth design meshes directly with the drive gear to translate driveshaft rotation into proportional speedometer needle movement. The gear features a natural (uncoated) finish, ensuring excellent durability and precise tooth geometry that maintains tight tolerances with the mating drive gear.

Mechanics and enthusiasts restoring or modifying first, second, and third-generation GM vehicles will find this component invaluable for maintaining speedometer accuracy, which is critical for both street legality and monitoring true vehicle performance.
