First, it is necessary to understand what the axle ratio is and how to find the Axle Ratio Dodge Ram 1500.
The axle ratio is the number of revolutions the drive shaft must make to turn one complete revolution. A representation of this number is the ratio, which is the number of gear teeth divided by the number of pinion teeth. For example, if a vehicle has an axle ratio of 3:73:1, the drive shaft will rotate 3.73 times for each full rotation of the wheel. Three different axle ratios, 3.73 and 3:73:1, are theoretically valid and imply the same thing when it comes to how an axle ratio should be constructed.
This may seem complicated to some, so we will walk you through the process of determining the axle ratio on your Ram 1500.
How to find Axle Ratio Dodge Ram 1500
Step 1: Locate the metal tag
Well, to locate the axle ratio on your Dodge Ram you need to find the metal tag. To locate it you will need to go through the rear axle carrier housing.
On the rear axle carrier housing of your Ram, you will see a small metal tag. The gear ratio of your Ram is on that label.
With that in mind, you will now need to search for your vehicle’s axle ratio.
Step 2: Place Drive Pan
Lift your Dodge Ram with your hydraulic jack very carefully.
Move the drive tray under the cover of the carrier housing.
Now you need to remove the bolts, usually, 13mm bolts, and use proper tools for this, such as a wrench or a socket.
Step 3: Count the gear ratio.
Once the bolts have been removed from the housing, you should be able to count the transmission ratio. We will show you how.
Rotate the tire, from there, you need to start counting the teeth of the large crown.
Now count the small pinion gears on your Dodge Ram 1500.
Now divide the small numbers by the larger number. This will give you the gear ratio of your Dodge Ram 1500.
Step 5: Clean the Gasket
Now, find a scraper for the gasket cover, once it is cleaned, continue with the next step.
Find a clean cloth, and clean the seal on the edge of the cover. But before that, you need to pour some RTV sealant around the edge of the cover that is in the sealing area and let it dry.
Step 6: Fill Carrier
Now, install the cover and install the 13 mm bolts and tighten them properly.
Find gear oil and pour it into the carrier and fill it. This process is done through the access plug.
How to tell when it’s full? easy, watch the gear oil, if you see the gear oil start coming out of the access hole of your Dodge Ram 1500, the process is done.
Step 7: Easy Axle Ratio
It is important to remember a few things while locating the axle ratio of your Ram 1500 to alter it to a different one later. As a result, the cruise RMP and speedometer will be adjusted accordingly.
In addition, you should make sure that the front and rear ratios are the same. Higher ratio numbers indicate better gearing, while lower ratio numbers indicate worse gearing.
If you see a gear ratio of 4.11, you should know that the drive axle will rotate 4.11 times for every rotation of the tire on the ground. If the number is 2.5, the tire will rotate two and a half times in total. Have you got an idea?
Simply put, the higher the number, the greater the amount of acceleration. If you want less acceleration, simply decrease the number in the equation. When inspecting your rear axle, look for the rear axle tag, as the front tag on the Dodge Ram 1500s is better protected than the rear, which will make the task easier.
How do you calculate an axle ratio?
The number of rotations of the transmission will help you determine your axle ratios. For example, if the result is 4 and a half, it would be a 4.50:1 axle ratio, on the other hand, if the result is 3 and a quarter, the axle ratio would be 3.25:1.
Can you change the axle ratio on a truck?
You can change your axle ratios quite easily. Many people switch to the following ratios.
People with an axle ratio of 3.21 and 3.55 change to an axle ratio of 3.92 and sometimes even an axle ratio of 4.10.
Many people have taken the axle ratios of their 4×4 trucks up to 4.10 or 4.56.
What is the difference between the 3.73 and 4.10 axle ratios?
The 4.10 axle ratio will prove to be an improvement in stop-and-go urban traffic, as it will provide greater acceleration, on the other hand, an axle ratio of 4.73 is ideal for towing heavy loads on flat terrain and will provide better fuel economy.
What gear ratio do I have by Vin?
Look for your VDS, which is the fourth through eighth digits of the VIN. It usually shows information about the vehicle model, model number, and body type. You can also locate the gear ratio on your VDS, although not all manufacturers include this information.
How can I tell what gear ratio I have without pulling the cover?
The easiest way to determine the transmission ratio is to locate the label that is attached to the cover on the differential bolts, there you can locate all the information about the standard axle ratio.
Is 3.23 a good gear ratio?
Yes, since, according to studies, this ratio provides an optimal balance between economy and performance.
I hope you understood the process of how to find the axle ratio Dodge Ram 1500, now you can easily change the axle ratio to the ratio you want.
Knowing this, make your Dodge Ram 1500 more powerful, because you and your truck deserve it. See you next time!
