you need to know exactly what gear in in the car and the height of the tire...


here is a for instance. i just went from a 2.94 gear to a 3.23 gear...

26" tire.

2.94 uesed a 30 tooth (small one in the picture) speedo gear..

3.23 uses a 33 tooth (larger one in the picture) gear.

speedo is dead on with my GPS


if you do change the speedo gear make sure you clock the speedo gear housing properly on install..
