3. What is a gear ratio, and how do I know what I have?

If you have a stock vehicle, look for the RPO codes on the door or in the glove box. GU2 = 2.73, GU5 = 3.23 and GU6 = 3.42. A gear ratio is the number of teeth on one gear compared to another. To find the ratio, you divide the number of teeth on the driven gear by the number of teeth on the driving gear. For instance, the number of teeth on a ring (driven) gear is 41. The number of teeth on a pinion (driving) gear is 10. 41 divided by 10 = 4.10.
