The best Jeep Wrangler JL upgrades include larger tires, axle regearing, and 4.10 or 5.13 axle gears, depending on the tire size.

Larger tires, such as those measuring 35 to 40 inches in diameter, can enhance the look and off-road capabilities of the Jeep.

However, it is important to consider the impact on power, drivability, and gear ratio.

To regain lost power due to larger tires, axle regearing is recommended.

The ideal gear ratio can be calculated using the formula RPM = 336 x (Final Drive Ratio X MPG) / (Tire Loaded Radius x 2).

For gas-powered Rubicon models with tires around 35 to 37 inches in diameter, 4.10 axle gears are ideal.

On the other hand, for tires larger than 37 inches, such as 38s or 40s, shorter 5.13 axle gears are recommended.

Larger Tires Considerations

When upgrading your Jeep Wrangler JL, changing to larger tires is a key consideration. This not only enhances the visual appeal of your vehicle, but also improves its off-road capabilities. Before making this modification, there are a few important factors to keep in mind:

  • Tire diameter: There are various options available, ranging from 35 inches to a whopping 40 inches. However, it’s essential to consider the trade-off between tire size and its impact on your vehicle’s power, drivability, and gear ratio.

  • Axle gearing: The impact of larger tires on your axle gearing should not be overlooked. Regearing the axles can help regain the power lost due to the increased tire size. Calculating the ideal gear ratio can be done using a simple formula: RPM = 336 x (Final Drive Ratio X MPG) / (Tire Loaded Radius x 2). This ensures your vehicle maintains optimal performance without sacrificing fuel efficiency.

Don’t forget to consider these important factors before upgrading to larger tires for your Jeep Wrangler JL.

Axle Regearing Importance

Axle regearing is an essential upgrade to consider when installing larger tires on your Jeep Wrangler JL. The primary purpose of regearing is to compensate for the power loss that occurs when larger tires are added to the vehicle. It allows you to regain lost power and ensure that your vehicle performs optimally.

By regearing the axles, you can adjust the gear ratio to suit the new tire size. This ensures that there is enough torque available to propel the vehicle efficiently. Without proper regearing, your Wrangler JL may experience a significant decrease in power, causing sluggish acceleration and reduced overall performance.

It is recommended to go for 4.10 axle gears if you have a gas-powered Jk or Jl Rubicon model with tires around 35 or 37 inches in diameter. These gears strike a balance between power and fuel efficiency, providing an optimal driving experience. With 4.10 axle gears, you can effectively harness the potential of your vehicle and conquer challenging off-road terrains with ease.

  • Axle regearing compensates for power loss caused by larger tires
  • Adjusting the gear ratio ensures sufficient torque for efficient propulsion
  • 4.10 axle gears are recommended for gas-powered Jk or Jl Rubicon models with 35 or 37-inch tires.
