by

Installing a Eaton Limited Slip Differential (LSD) on a 400-hp Mustang can significantly enhance performance and handling. This article explores the costs and benefits associated with this modification, helping you decide if it’s the right upgrade for your vehicle.

What is a Limited Slip Differential?

A limited slip differential is a type of differential that allows for some differentiation between the wheels while also providing power to both wheels. This is particularly beneficial in high-performance vehicles like the Mustang, where traction and stability are crucial.

Benefits of Installing a Eaton Limited Slip Differential

  • Improved Traction: An LSD provides better traction during acceleration, especially in slippery conditions.
  • Enhanced Cornering: It helps in maintaining stability and control while cornering, reducing the likelihood of oversteer.
  • Better Performance: It allows for more efficient power transfer to the wheels, improving overall performance.
  • Increased Durability: Eaton differentials are known for their durability and can handle higher torque loads.

Costs of Installing a Eaton Limited Slip Differential

While the benefits are substantial, it’s essential to consider the costs involved in installing a Eaton LSD on your Mustang. Here are some factors to keep in mind:

  • Purchase Price: The cost of the Eaton LSD itself can range from $800 to $1,500, depending on the model and specifications.
  • Installation Costs: Professional installation can add another $500 to $1,000 to your total cost, depending on labor rates in your area.
  • Additional Parts: You may need to purchase additional components, such as gears or bearings, which can increase costs.
  • Maintenance: Regular maintenance is required to ensure the differential operates correctly, which can incur additional expenses over time.

Installation Process

Installing a Eaton LSD involves several steps. Here’s a brief overview of the process:

  • Preparation: Gather all necessary tools and parts before starting the installation.
  • Remove the Old Differential: Lift the vehicle and remove the rear axle assembly to access the differential.
  • Install the Eaton LSD: Carefully install the new LSD, ensuring proper alignment and fit.
  • Reassemble: Reattach the rear axle assembly, ensuring all bolts are torqued to specification.
  • Test Drive: After installation, take the vehicle for a test drive to ensure everything is functioning correctly.

Performance Improvements

Once installed, you can expect noticeable improvements in your Mustang’s performance. Drivers often report:

  • Quicker acceleration from a standstill.
  • More confidence when navigating tight corners.
  • Reduced wheel spin during hard launches.
  • Overall enhanced driving experience.

Considerations Before Installation

Before proceeding with the installation, consider the following:

  • Driving Style: Assess whether your driving style warrants the upgrade.
  • Vehicle Use: Consider how often you drive your Mustang in performance situations.
  • Budget: Ensure you have a clear understanding of the total costs involved.
  • Future Modifications: Think about whether you plan to make other performance upgrades in the future.

Conclusion

Installing a Eaton Limited Slip Differential on a 400-hp Mustang can provide significant performance benefits, enhancing traction and handling. While the costs can be substantial, the advantages often justify the investment for performance enthusiasts. Evaluate your needs and budget to determine if this upgrade is right for you.
