Best answer for this question, how do I know what gear ratio My Jeep has?
You asked, what gear ratio came in a Jeep Wrangler? The stock gear ratio tends to vary depending on the year and package your Jeep has. Some of the possible ratios include 3.07, 3.55, 3.73, and 4.10. Wranglers that are equipped with the Rubicon package typically come with the 4.10 gear set in their Dana 44 axles.
Also the question is, how do I know my differential gear ratio? Count the number of teeth on the pinion gear and count the number of teeth on the ring gear. Divide the ring gear teeth number by the number of teeth on the pinion. The result is your gear ratio.
Likewise, can my VIN tell me my gear ratio? While it may be possible to derive information about an auto’s gearbox ratio from its VIN, that depends largely on the information the manufacturer includes in the vehicle descriptor section (VDS) of the VIN.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.

Why do Jeep have two sticks?
Jeeps were designed to have low and high gears for crawling up steep hills and powering down steep hills, respectively. The engine and transmission are designed so that the transmission would need to shift more often than with a single-speed transmission, so the two shifters minimize gear changes.
Should I Regear with 35s?
Yes, going to 35s you should definitely regear. And yes, the 4.10 to 4.86 is the proper range for 35s. You trade off will be fuel economy vs towing power. Being that your probably not going to be towing that much weight, you would probably be fine with the 4.10.
Why do you Regear a Jeep?
Regearing refers to the process of changing your pinion gears and ring gears to a different ratio, which changes the balance of torque and speed. Regearing your Jeep is a crucial step in adjusting the size of your tires since improper gearing can result in more stress being transferred to the axle.
What is the difference between 3.73 and 4.10 gear ratio?
Well-Known Member. 4.10s are going to accelerate faster and decelerate faster on lift. However the trade off is greater fuel consumption per mile driven and higher engine speed per given road speed. In basic terms the 4.10s will feel quicker and 3.73 will feel faster.
Is it better to have a higher or lower gear ratio?
Gear ratios can be boiled down to a single statement: Higher ratios (with a lower numerical value) give better torque/acceleration and lower ratios allow for higher top speeds and better fuel economy. Higher ratios mean the engine has to run faster to achieve a given speed.
Can you change the gear ratio on a truck?
You can change the axle ratio, and you can do it rather easily. Quite a few members here have gone from one ratio to the next. People with 3.21 and 3.55s are going up to 3.92 and even sometimes 4.10. A lot of the 4×4 trucks you see here with lifts and larger tires have gone with 4.10 or 4.56.
How do you decode a GM rear end?
How do I find out what gear ratio my Ram truck has?
Start the truck and put it into neutral. Rotate the rear tire 2 times and count the number of times the drive shaft turns. Close to 4 times = 3.92. Close to 3 1/2 = 3.55 Close to 3 = 3.21.
How do you check the gear ratio on a spinning tire?
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.
What gear ratio is best for 35 in tires?
That’s why I run a 4.56 gear ratio with 35″ tires. This gives me decent fuel efficiency at highway speeds, and enough low end power to throttle through difficult obstacles.
