How do I know my differential gear ratio?

Turn the wheel TWO revolutions and count the number of driveshaft turns. The number of driveshaft rotations will help you determine your rear axle ratio. For example, if it turned 3 and a half times, it’s a 3.50:1 ratio. If it turned 4 and a quarter times, it’s a 4.25:1 ratio. How do I know my dogs neck size? dog neck sizes by breed.

Does VIN number tell gear ratio?

How can I tell what gear ratio I have without pulling cover?

So an easy way to determine your actual gear ratio is to check the tag attached to the differential cover by the cover bolts. On the tag there should be some numbering such as 3.54 or 3.73, either of those numbers will give you the stock axle ratio.

How can you tell the difference between a 3.73 and a 4.10 gear ratio?

So for gear ratio of 3.73, for every one turn of the ring gear, the pinion will turn 3.73 times and for gear ratio of 4.10, for every one turn of the ring gear, the pinion will turn 4.10 times. The ratio is the number of teeth on the driven gear (ring) divided by the number of teeth on the drive gear (pinion).

How do you read a gear ratio chart?

The ratio is the number of teeth on the driven gear (ring) divided by the number of teeth on the drive gear (pinion). So, if the ring gear has 37 teeth and the pinion has 9 teeth, the ratio is 4.11:1. That also means that for every one turn of the ring gear, the pinion will turn 4.11 times.

Which gear ratio is faster?

A lower (taller) gear ratio provides a higher top speed, and a higher (shorter) gear ratio provides faster acceleration. . Besides the gears in the transmission, there is also a gear in the rear differential. This is known as the final drive, differential gear, Crown Wheel Pinion (CWP) or ring and pinion.

  1. Gear Ratio = Number of Teeth in Chain Ring ÷ Number of Teeth in Rear Cog.
  2. Gear Inches = Diameter of Rear Wheel x (Number of Teeth in Chain Ring ÷ Number of Teeth in Rear Cog)

What is differential gear ratio?

Differential Gear Ratio determines the number of times the drive shaft (or pinion) will rotate for each turn of the wheels (or ring gear). … If you originally had 3.07 gears you need a ratio that is approximately 17% lower, such as 3.55. If you want to increase off road performance you might want a 4.10 or lower ratio.

Do bigger tires affect gear ratio?

When changing gears for taller tires, you are heading to a numerically higher gear ratio. The higher the gear ratio, the smaller the pinion gear. You do not want go too low in an effort to increase power to the wheels and/or relieve stress in the rest of the drivetrain.

How can I make my gear ratio higher?

Gear ratio is the ratio of number of teeth of the driving and the driven gear. Gear ratio = number of teeth on driven gear/number of teeth on driving gear. Now if you want to increase gear ratio, just increase the number of teeth on driven gear or decrease the number of teeth on driving gear.

How do I identify my Chevy truck rear end?

All Chevrolet rear ends can be identified by comparing the gasket shape to an identification chart similar to the one found on Drivetrain’s differential identification page (see References). A visual chart of different GM/Chevrolet rear ends is found on Ring & Pinion’s differential types web page (see References).
