How many teeth does a 3.73 ring have?

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 many teeth does a 3.73 ring gear have?

3.73 gears have 11 pinion gear teeth & 41 ring gear 41/11= 3.727 to 1.

How many teeth are on a 373?

Motive Gear D30-373 Rack and Pinion, 41-11 Teeth, 3.73 Ratio.

How many teeth does 4.88 gears have?

Motive Gear D35-488 Rack and Pinion, 39-8 Teeth, 4.88 Ratio.

Are 3.73 or 4.10 gears better?

4.10 gear ratio:

4.10 is the typical gear ratio for a high-performance vehicle like a sports car or SUV because it provides better acceleration than 3.73 because of the faster second and third gears, which provide more torque at lower speeds to accelerate from a stop.

What is a 3.73 rear axle ratio?

This number is shown in the ratio, which represents the number of the ring gear's teeth divided by the number of the pinion's teeth. If a truck has an axle ratio of 3:73:1, for example, the driveshaft turns 3.73 times for each full wheel spin.

How do you calculate ring and pinion gear ratio?

How many teeth should a pinion gear have?

Summary. Empirically, a pinion with approximately 20 teeth is optimal. That is why Apex Dynamics has invented the “Curvic Plate” pinion, in which the torque, backlash, wear and service possibilities are optimal.

How many teeth does a 342 ring gear have?

Richmond Ring & Pinion Set - 3.42 Ratio, 41-12 Teeth, GM 10 Bolt (70-94) 49-0278-1.

How do you determine the number of teeth on a pinion?

The number of teeth (z). This value is: z = d/m. Module (m). Ratio between the pitch circle in millimeters and the number of teeth.

How do you calculate gear teeth?

Now we have the gear ratio i=d2/d1=z2/z1 (gear 1 is the driving gear, and gear 2 is the driven gear). The module also has to do with the tooth height, for standard gears, the tooth height equals to 2.25*m: addendum ha=1*m, dedendum hf=1.25*m, tooth height h=2.25*m.

Can you tell the gear ratio by the VIN number?

The gear ratio is usually listed in the VIN code located on driver's door, the glove box, or the ID plate on the dashboard. Count the times a rear wheel goes around for one driveshaft turn: if its 3 1/2 it's a 3.50:1. Divide the number of teeth on the ring gear by the number of teeth on the pinion gear.

What are 3.73 gears good for?

FACT: A 3.73 axle ratio is ideal for towing heavy loads on flat terrain and will produce increased fuel economy during steady-state, long-distance highway driving.

What are 3.55 gears good for?

PERFORMANCE: The larger the axle ratio number, the quicker the truck will accelerate. For example, a truck equipped with 3.55:1 axle gearing will accelerate faster than one equipped with a 3.31 axle ratio.

Are 4.10 gears good for highway?

Installing 4.10 gears improves the car's performance on the track but with negligible effects to the highway driving. If your car is equipped with an overdrive, you may not even notice a difference in gas mileage with the new higher gearing.

How can you tell if you have 3.73 gears?

Rotate the marked tire one revolution while counting how many times the driveshaft rotates. eg, If your driveshaft made 3 3/4 revolutions, that would determine a 3.73 gear ratio. If you get approximately 2 3/4 revolutions, you have a 2.76 gear ratio.

Are 3.73 gears good for 35 tires?

You will be fine. Just gonna lose mpg and slow your truck down. I have run 35s with 3.73s and no issues at all. In fact, my recent Plat had a 4-inch lift, heavy 34.5 inch Nitto Trails, and 3.55 gears, and ran great!

What is the difference between 3.55 and 3.73 gears?

With the 3.55 gear, the engine turns 3.55 revolutions for each revolution of the axle. With the 3.73, the engine turns 3.73 times for each revolution of the axle. So a lower gear (3.73, 4.11, 4.30, etc) makes the engine run at a higher RPM for a given speed (i.e. 60 MPH).

Will 4.88 gears fit in a Dana 30?

Yes 4.88 gears will work in your Dana 30 and Dana 35 axles.

What is a pinion gear?

Pinion Gear – A pinion is the smaller of two meshed gears in an assembly. Pinions can be either spur or helical type gears, and be either the driving or driven gear, depending on the application. Pinion gears are used in many different types of gearing systems such as ring and pinion or rack and pinion systems.

What is ring and pinion gear ratio?

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.
