New reproduction 1957-1982 Corvette 20 tooth speedometer driven blue gear. Speedometer driven gears mount inside manual or automatic transmission where the speedometer cable attaches. Gears vary upon transmission, differential ratio and tire size. Correct usage can be identified by # of teeth and color of gear. Gears are often found broken and unable to properly drive the speedometer cable OR need to be replaced to provide more accurate speedometer readings due to changes in tire size or differential ratio.
Note: Changes in gear can affect how the speedometer reads. If you speedometer is reading fast, install a gear with more teeth to reduce speed. If your speedometer is reading slow, install a gear with less teeth to correct speedometer. One (1) tooth = approximately 1.5 mph. Gear sleeve may need to be changed when changing the gear usage.
