How do I know my axle gear ratio?
Method 1: Count the number of teeth on the ring gear and the pinion. Divide the number of the ring gear’s teeth by the number of the pinion’s teeth. This will give you the axle ratio.
How do you calculate rear differential ratio?
The calculation uses the number of teeth in the ring gear and divides it by the number of teeth in the pinion gear to provide you with a “[result] to 1” ratio. For example, if the pinion gear has 41 teeth, and the ring gear has 11 teeth, the ratio would be calculated as 41/11, which is equal to 3.73 = 3.73:1.
How do I know my tire gear ratio?
Here’s the formula for calculating gear ratio: (RPM x Tire Diameter Inches) / (Final Drive Ratio x Transmission Gear Ratio x 336) = Actual numerical gear ratio to the ground from every revolution of the engine.
How do you calculate rear end gear ratio without overdrive?
FIGURING REAREND GEAR RATIO (Ring & Pinion) FORMULA: Engine RPM @ Cruise / Tire Revolutions Per Mile = Rear-end Gear Ratio EXAMPLE Without Overdrive: 1800 RPM / 656.93811 = 2.73:1 EXAMPLE Without Overdrive: 2000 RPM / 656.93811 = 3.04:1. EXAMPLE With Overdrive (30\%): 1800 RPM / 656.93811 = 2.73:1 x 130 = 3.54:1
What is the diameter of a GM rear end differential?

Should I change gear ratios?
If your looking for more power or performance, you would switch to a lower ratio. It’s just backwards from the way we think, if you have a 4.10 ratio and need better fuel mileage you would switch to a 3.42 or 3.73 gear ratio. If you have a 3.42 rear end ratio and need more towing power you would switch to a 4.10 ratio.
What is the best rear end ratio for towing?
If you have a 3.42 rear end ratio and need more towing power you would switch to a 4.10 ratio . If you have installed larger tires, they rob performance, and you would want to go to a lower ratio like a 4.56 or 4.88 depending upon your tire diameter.
