- (1) 20T (Red) Speedometer Pinion Assembly*
Choosing the right speedometer pinion is very important. One size too large or small will cause your speedometer to give an incorrect reading. Fortunately, Nissan gave us two ways to identify the gear in your car: tooth count and color. *This genuine, original equipment (OEM) assembly includes the 20-tooth (red) pinion gear, housing, large and small o-rings, and retaining pin.
This size speedo pinion was not originally found in Z-Car transmissions. It was offered from Nissan Competition for race drivers that changed the gearing in their differential or were using a Nissan Competition transmission.
