Xj Cherokee Power Gains: Installing a 4.56 Gearing and Lockers for Better Towing and Off-road Ability

The XJ Cherokee is a versatile vehicle known for its off-road capabilities and towing power. Enhancing these attributes can significantly improve your driving experience, especially if you frequently tow or venture off the beaten path. One effective way to achieve this is by installing 4.56 gearing and lockers. This article will explore the benefits and the process of upgrading your XJ Cherokee for better performance.

Understanding Gearing and Lockers

Before diving into the installation process, it’s essential to understand what gearing and lockers are and how they affect your vehicle’s performance.

What is Gearing?

Gearing refers to the ratio of the drive shaft’s rotation to the rotation of the wheels. A lower gear ratio, such as 4.56, provides more torque, which is particularly beneficial for towing and climbing steep terrains.

What are Lockers?

Lockers are devices that lock the differential, ensuring that both wheels on an axle turn at the same speed. This is crucial for off-road driving, as it provides better traction when navigating uneven surfaces.

Benefits of 4.56 Gearing and Lockers

Installing 4.56 gearing and lockers can provide several advantages for your XJ Cherokee:

  • Improved Towing Capacity: The increased torque from lower gearing allows for better towing performance.
  • Enhanced Off-Road Ability: Lockers provide superior traction, allowing for better maneuverability on rugged terrains.
  • Better Acceleration: Lower gearing improves acceleration, making it easier to start from a stop or climb hills.
  • Increased Control: Lockers give you more control over your vehicle in challenging situations.

Installation Process

Installing 4.56 gearing and lockers requires mechanical knowledge and the right tools. Here’s a step-by-step guide:

Tools and Materials Needed

  • Socket set
  • Torque wrench
  • Differential cover gasket
  • New ring and pinion gears (4.56 ratio)
  • Lockers (select the type based on preference)
  • Gear oil
  • Shop manual for your specific XJ Cherokee model

Step-by-Step Installation

  • Prepare the Vehicle: Lift the vehicle and secure it on jack stands. Remove the wheels and the differential cover.
  • Remove Old Gears: Take out the old ring and pinion gears carefully, noting the setup for reassembly.
  • Install New Gears: Follow the manufacturer’s instructions to install the new 4.56 gears, ensuring proper alignment and backlash settings.
  • Add Lockers: Install the lockers according to the specific instructions provided with the product.
  • Reassemble: Reattach the differential cover with a new gasket, and refill with the appropriate gear oil.
  • Test Drive: Once everything is reassembled, take the vehicle for a test drive to ensure everything is functioning correctly.

Considerations Before Installation

Before proceeding with the installation of 4.56 gearing and lockers, consider the following:

  • Skill Level: Ensure you have the necessary mechanical skills or consult a professional.
  • Cost: Factor in the cost of parts and potential labor if hiring a mechanic.
  • Vehicle Use: Assess how often you will be towing or off-roading to determine if the upgrade is worth it.
  • Future Modifications: Consider how this upgrade fits into your overall plans for the vehicle.

Conclusion

Upgrading your XJ Cherokee with 4.56 gearing and lockers can significantly enhance its towing and off-road capabilities. By understanding the benefits and following the installation process, you can enjoy a more powerful and versatile vehicle. Whether you are an avid off-roader or frequently tow heavy loads, these modifications can make a substantial difference in your driving experience.
