FAQ

What are speedometer gears and why are they important?
Speedometer gears connect your transmission’s output shaft to the speedometer cable or sensor, ensuring your speedometer displays your true vehicle speed. The correct tooth count compensates for changes in tire size or axle ratio.

How do I select the right speedometer gear for my setup?
You'll need to know your transmission type, axle ratio, tire diameter, and sometimes the number of teeth on your drive gear. Use our online charts or contact us for personalized assistance.

What’s the difference between drive and driven speedometer gears?
The drive gear (on the transmission output shaft) turns the driven gear (attached to the speedometer cable or sensor). Adjusting the driven gear tooth count is the most common way to correct speedometer readings.

Are your speedometer gears compatible with all transmissions?
We offer gears for popular GM, Ford, Mopar, and import applications. Always check product fitment details for your specific transmission model.

Can I install speedometer gears myself?
Yes! Most driven gears are easy to swap with basic tools and a little transmission fluid. Drive gear changes may require removing the tailshaft housing and are more involved.

Are these gears suitable for both mechanical and electronic speedometers?
Yes! Many work for both cable-driven and electric speed sensors—always check your gauge/sensor setup and product description to be sure.

What if my speedometer gear doesn’t fit or is defective?
Customer satisfaction is our priority. If your gear doesn’t fit or arrives faulty, contact us within 7 days for a replacement, exchange, or refund.
