Both the ring gear and the pinion gear should have an equal number of teeth. Divide the ring gear’s total number of teeth by the pinion’s total number of teeth. Your gear ratio is the end outcome.

What is the Nissan Titan’s rear axle ratio?
In comparison to the Titan, which has a smaller final gear ratio, the 4.083:1 offers higher torque at the wheels in a given gear as well as smoother and quicker acceleration.
How do you determine a truck’s gear ratio?
If your axle ratio isn’t listed in your literature, there are two methods you can figure it out on your own. You can get your differential open and examine the ring gear and pinion gear if you have the mechanical aptitude to remove the cover plate. The axle ratio is determined by the number of teeth on these gears, which transmit engine power.
The larger gear connecting to the axle is the ring gear, while the smaller gear attached to the driveshaft is the pinion gear. Divide the total number of teeth on the ring gear by the total number of teeth on the pinion to arrive at your ratio.
If you don’t want to open up your differential, turning the wheel will provide a ballpark approximation. Make a mark on the driveshaft when your truck is raised and in neutral, then turn one of the rear wheels completely. The approximate axle ratio can be determined by counting the rotations of the driveshaft.
How can I tell what differential my Nissan has?
The axle code, which can be used to calculate the differential gear ratio, is listed on the VIN tag, which is normally found on the driver-side door jamb. There will be two letters and two numbers in the code. The gear ratio will be shown by the number and the type of rear end will be indicated by the letters.
How can I determine my gear ratio without opening the cover?
Even though you may believe you are familiar with your Jeep’s gear ratios based on its year and/or differential type, if you bought the car used, it’s possible that someone has already changed them. So, checking the tag fastened to the differential cover by the cover bolts will quickly reveal your real gear ratio. Any figure like 3.54 or 3.73, which may be found on the tag, will tell you what the stock axle ratio is. You can jack up the back axle and support it using jack stands to confirm or check to see if that ratio has changed. Rotate the back driveshaft manually with the transmission in neutral. Calculate how many rotations of the driveshaft it takes for one tire rotation.
The driveshaft has a 3.54 ratio, for example, if it revolves around 3-1/2 times. While performing this test, it can be useful to mark a reference point on the tire and driveshaft with chalk or a grease pencil.
A Nissan Titan weighs what tonnage?
A 3/4 ton truck is what? Even heavy-duty pickup trucks from the past could only carry 1,500 pounds, or 3/4 of a ton, of freight. The majority of modern heavy-duty pickup trucks can carry over 4,000 pounds at once. However, the category’s name has not changed.
The U.S. government classifies trucks based on their gross vehicle weight rating (GVWR), which includes both the vehicle’s combined weight and its maximum payload. All automobiles with a GVRW between 8,501 and 10,000 pounds fall under Class 2B. The Ford F-250, Ram 2500, and Chevrolet Silverado/GMC Sierra 2500 are all part of what is frequently referred to as the 3/4-ton class.
With technology from their heavy-duty full-ton trucks, Ram, Ford, and General Motors all construct their 3/4-ton trucks. Because of this, you may equip any of these 3/4-ton trucks with a 10,000-pound GVWR option.
The GVWR of these vehicles is far more than that of the Nissan Titan XD. However, its GVWR of 8,650 to 8,800 pounds categorizes it as a heavy-duty, 3/4-ton truck.

What makes the gear ratios of 3.73 and 4.10 different?
That 3.73 vs. a 4.10 has a significant impact on engine rpm because, with a 3.73, you must select second gear to pull the grade, but, with a 4.10, you can shift into third gear. The temperatures beneath the hood will be substantially lower because your engine is running at a speed that is around 1,000 rpm lower.
A decent 3.73 gear ratio for towing
A truck with the optional 3.73 gear ratio may therefore carry a heavier trailer than one with the 3.55 or 3.21 gear ratios. But because the engine’s rpm will be higher, it will also use more fuel in every circumstance.
What advantages do I have?
By jacking up the vehicle and spinning one of the rear tires, you may quickly determine if you have an open differential. You have an open differential if the other wheel spins the other way. You have a limited slip differential, or LSD, if it spins in the same way.
What 10 bolt rear end do I have, and how do I know?
The housing’s form and the distance between the bottom bolts on the cover make it simple to recognize an 8.2-inch rearend at a glance. The 11.2-inch cover has a diagonal protrusion at the top, while the 8.2-inch 10-bolt has a smooth, round, lower-case region (no cast-in protrusions).

When buying a new pickup truck or SUV, choosing between rear- and four-wheel drive and choosing an engine are crucial steps, but paying attention to axle ratios is also crucial. A new GMC vehicle or SUV can be further customized to meet your needs by ordering the appropriate axle ratio.
Gearing in axles and differentials enables the transmission of power from your engine and driveline to the wheels. A solid pinion gear inside the axle is attached to a driveshaft that is spun by the engine and transmission. A larger gear known as a ring gear is turned by the pinion by engaging with it. The differential case, which houses lower gears that enable chatter-free cornering and ultimately transfer power to the wheels, is connected to the ring gear.
The driving shaft will rotate at a faster rate than the axle shafts and wheels because the pinion is smaller in diameter than the ring gear. Axle ratio is the name given to this ratio. Axle ratios are sometimes written in notation as something like “3.42:1, or a “3.42 rear axle. In either scenario, it effectively means that in order to rotate the axle shafts once, the driving shaft and pinion must turn 3.42 times.
The ratio may be referred to as a larger numeric ratio if the increase in the number of drive shaft rotations necessary to turn the wheel (4.10:1) occurs. In general, higher numeric axle ratios offer greater torque while requiring the driveline to turn the wheel more frequently in order to turn it once. This can aid enhance off-the-line acceleration and help provide pulling force when pulling big loads or trailers.
Conversely, the ratio is referred to as a lower numeric axle ratio if the amount of drive shaft spins necessary to turn the wheel increases (i.e., something like a 3.08:1) Lower numeric axle ratios may assist an engine work less hard while traveling at highway speeds, which may aid fuel economy.
The standard axle ratio found in a GMC truck or SUV has been carefully chosen to provide the optimum overall blend of performance, towing capacity, and efficiency based on the vehicle’s unique body shape and engine. One notable example of an all-around mix is the 3.42:1 ratio found on several Canyon V-6 and Sierra 1500 models.
Having said that, take into account a truck with a higher numeric axle ratio if you frequently tow hefty trailers or desire a peppier feel during acceleration. Although larger numeric axle ratios offer more pulling power, they typically lead to a decrease in fuel efficiency since the engine will need to rev higher at a given vehicle speed than a similar truck with a lower numeric axle ratio.
Differential gear ratio: what is it?
The number of rotations the drive shaft (or pinion) will undergo for each wheel turn is determined by the differential gear ratio. A drive shaft turns 3.73 times for every wheel rotation if your gear ratio is 3.73:1.
The final drive ratio changes as tire size changes. The final drive ratio is altered by approximately 17% when going from a 30 to a 35 tire. This could cause the engine to lose some of its “power band” and have poor performance and fuel efficiency as a result. You must adjust the gear ratio to account for the change in tire size in order to restore performance. If your original gear ratio was 3.07, you’ll need a ratio that’s roughly 17% lower, like 3.55. A 4.10 or lower ratio would be preferable if you wish to improve off-road performance.

What is a rear axle ratio of 3.73?
The amount of rotations the driveshaft or output shaft must perform in order to rotate the axle one full turn is known as the axle ratio. The amount is expressed as a ratio, which is the product of the ring gear’s tooth count and the pinion’s tooth count. For instance, a vehicle with a gear ratio of 3.73:1 means that the driveshaft will rotate 3.73 times for every full wheel rotation. Instead of writing the axle ratio as 3.73:1, many people just say it as 3.73. But they both convey the same meaning.
