Are 3.73 or 4.10 gears better?
ARE 3.73 OR 4.10 GEARS BETTER? Use this rule of thumb: The shorter the gear ratio (higher number), the easier it will be for the vehicle to start moving and accelerating! This will, however, lower the top speed of the vehicle.
What gears for 36 inch tires?
As you can see from the above formula, 3.73 gears with 36″ tires is optimum for restoring stock performance with this truck. Keep in mind that not all ratios are available for every axle, so do some research to make sure there’s a ratio close to what you need available for your truck’s axles.
Is a higher gear ratio better for bigger tires?
The gear ratio determines how much torque is transferred from the engine to the wheels. If the tire size is larger, the gear ratio must be lower to compensate for the increased diameter, and vice versa. A low gear ratio provides more torque to the wheels, which is ideal for off-roading or towing heavy loads.
How long do Jeep JK transmissions last?
On average, a transmission in a Jeep Wrangler can last anywhere from 100,000 to 200,000 miles.

Why do you have to Regear after getting bigger tires?
When you switch over to larger tires, that balance is upset by their extra height, weight, and rolling resistance. You’ll also likely experience slower acceleration. One solution is to consider re-gearing your vehicle’s differential when installing taller tires.

Are 35 inch tires too big?
A 35 inch tall tire is still a big tire. It will affect your final drive ratio, and your braking, but many people will gladly accept that for the increase in traction. There is a camp that typically drives in muddy conditions who like tall narrow tires.
What is the difference between 35s and 37s?
The most obvious difference between these tires is their height. The numbers 33, 35, and 37 stand for the height of the tires in inches. Therefore, the 37 tires are the tallest, the 33s are the shortest, and the 35s are in the middle. With taller-sized tires comes a taller ride height.

Why Regear?
When you install bigger tires on your JK, you’re essentially changing the tire diameter and the overall gear ratio of your drivetrain. That means your engine has to work harder to turn those larger tires, and you might experience a decrease in power and acceleration. Regearing is the solution to this problem. It helps your Jeep perform at its best with bigger tires.
What’s a Gear Ratio?
Think of a gear ratio like a lever. A higher ratio gives you more leverage, while a lower ratio requires more effort. In your Jeep’s drivetrain, the gear ratio is the ratio of teeth on the ring gear to the teeth on the pinion gear. A higher gear ratio means your engine has to work harder, but you get more torque and pulling power. A lower gear ratio means your engine works less hard, but you have less torque.
Choosing the Right Gear Ratio
This is where things get a little technical. To choose the right gear ratio for your JK with 35s, you need to consider a few factors:
Engine size: A larger engine can handle a lower gear ratio, while a smaller engine might need a higher ratio.
Transmission: Automatic transmissions generally work well with lower ratios. Manual transmissions might require a higher ratio.
Driving style: If you do a lot of off-roading, you’ll want a gear ratio that gives you plenty of torque for climbing hills and crawling over rocks.
Desired performance: If you want more power and acceleration, you’ll want a higher gear ratio.
A good starting point is to consider a 4.88 or 5.13 ratio for 35s. You can use online calculators to help you determine the best ratio based on your Jeep’s specs.
The Regearing Process
Regearing your Jeep JK is not a simple bolt-on mod. It’s a complex process that involves replacing the following components:
Ring and Pinion Gearset: This is the heart of your rear differential.
Differential Cover: You’ll need a new cover to accommodate the new gears.
Shims: These are used to adjust the backlash and pinion depth.
Master Install Kit: This kit includes all the necessary parts for a proper installation.
Important Note: This is a serious mechanical job. If you’re not comfortable working on your Jeep’s drivetrain, it’s best to have a professional mechanic do the work.
What to Expect After Regearing
Once you’ve regeared your Jeep, you’ll notice a significant difference in its performance:
Improved Off-Road Performance: You’ll have more power and torque for climbing hills and crawling over rocks.
Better Fuel Economy: Your engine will be working less hard, leading to improved fuel economy.
Improved Acceleration: You’ll get a noticeable improvement in acceleration.
Higher RPMs at Highway Speeds: Your engine will run at higher RPMs when you’re cruising on the highway.
