Do I Need To Regear My Jeep With 35s: Is It Really Necessary?

Regearing your Jeep is necessary if you plan to use 35-inch tires. Increasing the tire size of your jeep affects its gear ratios and drivability.

Without proper gearing, you may experience a decrease in power and acceleration. This can cause strain on your engine and transmission, potentially leading to costly repairs. Regearing your jeep helps to maintain its performance and improve fuel efficiency. It also allows for better off-road performance, making climbing steep inclines and navigating rough terrain easier.

In this article, I will discuss do I need to regear my Jeep with 35s. A professional mechanic can help determine the appropriate gear ratio for your jeep and install the necessary components. So, scroll down.

Regearing Your Jeep for 35s: Is It Really Necessary?


Understanding Gear Ratios

If you’re considering upgrading your jeep’s tire size to 35 inches, you may need to regear your vehicle. This is because it’s crucial to have the right gear ratio to match your tire size to ensure optimum power delivery, acceleration, and overall performance.

Understanding gear ratios is essential to make the right decision.

Explanation Of Gear Ratios

Gear ratio is the relationship between the number of teeth on the ring gear and the pinion gear in the differential. In simple terms, it’s the difference between revolutions of the driveshaft and wheels. The numerical value of a gear ratio indicates how many turns of the driveshaft are required to turn the wheel one full revolution.

For example, a 4. 10 gear ratio means that the driveshaft rotates 4. 10 times to make the wheels turn once.

How Gear Ratios Affect A Jeep’S Performance

Gear ratios significantly impact a jeep’s performance, especially when you upgrade to larger tires. If the gear ratio is too low, it’ll be difficult to accelerate and provide enough power to climb steep hills or rocks. On the other hand, a higher gear ratio will reduce your jeep’s top speed, affecting fuel economy and highway performance.

Importance Of Choosing The Right Gear Ratio For Specific Tire Sizes

Choosing the correct gear ratio is essential for optimal performance and preventing damage to your jeep’s drivetrain. If you don’t match the gear ratio to your tire size, it’ll stress the transmission, drive shaft, and axles unnecessarily, leading to mechanical failures and costly repairs.

By regearing your jeep, you can ensure the engine is always in the power band and deliver maximum torque to the wheels.

Examples Of How Gear Ratios Affect Driving And Performance

To get a better idea of how gear ratios affect driving and performance, let’s take a look at some examples:

  • With a stock gear ratio of 3.73 and stock tire size of 31 inches, your jeep can comfortably run at highway speeds and climb hills without much effort.
  • If you upgrade to 35-inch tires without regearing, your jeep’s engine will struggle. A higher gear ratio of at least 4.56 will provide better off-road performance and fuel economy.
  • If you mostly drive on the highway and occasionally hit the trails, a gear ratio of 4.10 would balance acceleration and top speed while still providing enough crawling power.

Understanding gear ratios is critical to improving your jeep’s performance and longevity. It’s essential to take into account your driving style and intended use to select the appropriate gear ratio when upgrading your tire size. Don’t forget to consult with a professional mechanic to ensure a safe and effective regearing process.

Common Issues When Upgrading To 35S And How Regearing Can Help

Upgrading to 35s can cause several issues for your jeep. Here are some common issues you may face and how regearing can help:

  • Speedometer calibration issues: The larger tires will affect your jeep’s speedometer. Regearing can help you to recalibrate the speedometer to get accurate readings.
  • Braking problems: The bigger tires will make your jeep take longer to stop. Regearing will help to improve braking performance and reduce stopping distances.
  • Loss of power: Upgrading to 35s can cause a loss of power and acceleration. Regearing can help to restore lost power and acceleration.

Comparison Of Different Gear Ratios

Different gear ratios are available for upgrading to 35s. Here’s a comparison of some of the most popular gear ratios:

  • 4.10: 1 – best for daily drivers and off-roaders who do a lot of highway driving
  • 4.56: 1 – ideal for off-roaders who do a lot of crawling and rock climbing
  • 4.88: 1 – best for the extreme off-roaders who need maximum performance

Cost Considerations And Factors To Keep In Mind When Regearing

Regearing can be a costly process. Here are some cost considerations and factors to keep in mind:

  • Labor costs – the labor cost depends on the mechanic you choose to do the job.
  • Gear ratio – the cost of the gear ratio will differ depending on the brand and type you choose.
  • Axle upgrades – upgrading your axle may be necessary, which can be an expensive process.
  • Tires – upgrading to 35s can be expensive, and you need to factor in the cost of new tires.

Regearing your jeep is an essential process if you want to upgrade to 35s. Make sure you choose the right gear ratio, consider the benefits, the common issues, and the cost factors before you make the decision to regear.
