Mazda speedometer sensor for 3.63 final drive

DESCRIPTION

For use with our 3.63:1 ring and pinion set. Calibrated for the 3.63 ratio so your speedometer isn't off when you change your ring & pinion to our 3.63 ratio.
Fits 1999-2005 Miata, including 04-05 Mazdaspeed.

For use ONLY by those who have changed to the 3.63 ring and pinion that we offer separately on our site.
This is NOT the stock replacement for your speedometer sensor if you still have the stock ratio in your differential. If you have a stock ratio diff and use this sensor, your speedometer will be off because this sensor is not calibrated for the stock ratio.
