Upgrading Suspension and Drivetrain for a 700 Hp Wrangler Ls Swap

by

The process of upgrading the suspension and drivetrain for a 700 HP Wrangler LS swap involves several critical steps that ensure performance, safety, and reliability. This article will guide you through the essential upgrades needed to handle the power of a high-performance engine.

Understanding the Need for Upgrades

When swapping in an LS engine that produces 700 horsepower, the stock suspension and drivetrain components of a Jeep Wrangler may not be sufficient. Upgrading these components is crucial for maintaining control and stability while driving. Here are the main reasons for these upgrades:

  • Increased power demands on drivetrain components
  • Improved handling and ride quality
  • Enhanced safety during high-speed maneuvers
  • Better traction and stability on various terrains

Suspension Upgrades

Upgrading the suspension is vital for a vehicle with an LS swap. The following components should be considered:

  • Coilovers: Adjustable coilovers allow for customized ride height and improved handling.
  • Control Arms: Upgraded control arms provide better articulation and strength.
  • Sway Bars: Heavier duty sway bars reduce body roll during cornering.
  • Shock Absorbers: High-performance shocks improve ride quality and response.

Choosing the Right Coilovers

When selecting coilovers, consider factors such as adjustability, damping settings, and compatibility with your Wrangler model. Brands like Fox and King offer high-quality options that can handle the demands of a 700 HP setup.

Control Arms and Sway Bars

Investing in heavy-duty control arms and sway bars will significantly improve your vehicle’s handling. Look for components made from durable materials like aluminum or reinforced steel to withstand the increased stress from the LS engine.

Drivetrain Upgrades

The drivetrain must also be upgraded to support the power output of a 700 HP LS engine. Key components include:

  • Transmission: A high-performance transmission, such as a 4L80E or TH400, is recommended for handling increased horsepower.
  • Driveshaft: A stronger driveshaft is essential to prevent failure under high torque conditions.
  • Differentials: Upgrading to heavy-duty differentials ensures reliability and performance.
  • Axles: High-strength axles are necessary to handle the power and avoid breakage.

Transmission Selection

Selecting the right transmission is crucial for a successful LS swap. The 4L80E offers a good balance of strength and versatility, while the TH400 is a robust option known for its durability. Ensure compatibility with your engine and transfer case.

Driveshaft and Differential Considerations

A custom driveshaft may be necessary to accommodate the new transmission and lift height. For the differential, consider upgrading to a 4.10 or 4.56 gear ratio to match the power output and improve acceleration.

Braking System Enhancements

With the added horsepower, upgrading the braking system is essential for safety. Consider the following:

  • Brake Rotors: Larger, slotted, or drilled rotors improve heat dissipation and stopping power.
  • Calipers: Upgrading to multi-piston calipers increases clamping force.
  • Brake Lines: Stainless steel brake lines provide better pedal feel and durability.
  • Master Cylinder: A larger master cylinder ensures sufficient fluid delivery for enhanced braking performance.

Choosing Brake Components

When selecting brake components, prioritize quality and compatibility with your Wrangler. Brands like Wilwood and Baer offer performance upgrades that can significantly enhance braking efficiency.

Final Considerations for Your LS Swap

Completing a 700 HP LS swap in a Wrangler requires careful planning and execution of various upgrades. Here are some final considerations:

  • Alignment: After upgrading suspension components, a proper alignment is crucial for handling and tire wear.
  • Tuning: A professional tune is necessary to optimize engine performance and reliability.
  • Testing: Thoroughly test the vehicle in various conditions to ensure all systems function correctly.
  • Documentation: Keep records of all upgrades and modifications for future reference and maintenance.

By following these guidelines, you can successfully upgrade your Wrangler’s suspension and drivetrain to handle the power of a 700 HP LS engine. Enjoy your enhanced driving experience!
