Supporting Mods for a 650 Hp Ls Swap 240sx: Upgraded Driveshafts, Axles, and Differential Upgrades

by

The Nissan 240SX is a popular platform for enthusiasts looking to swap in a powerful LS engine. With a 650 HP LS swap, it is crucial to consider supporting modifications to ensure reliability and performance. In this article, we will explore the importance of upgraded driveshafts, axles, and differential upgrades for a successful LS swap in your 240SX.

Why Supporting Mods are Essential

When swapping an LS engine into a 240SX, the increase in horsepower and torque can put significant stress on the vehicle’s drivetrain components. Upgraded driveshafts, axles, and differentials are essential to handle the added power and ensure the longevity of your performance build.

Upgraded Driveshafts

An upgraded driveshaft is one of the first modifications to consider when performing an LS swap. The stock driveshaft may not be able to handle the increased torque from a 650 HP engine, leading to potential failures and unsafe driving conditions.

  • Material: Consider a driveshaft made from lightweight materials such as aluminum or carbon fiber, which can reduce rotational mass and improve performance.
  • Diameter: A larger diameter driveshaft can provide additional strength and torque handling capabilities.
  • Length: Ensure the driveshaft is properly lengthened or shortened to fit your LS swap setup.

Upgraded Axles

With the power increase from the LS engine, the stock axles of the 240SX may struggle to keep up. Upgrading the axles is essential to prevent breakage during hard launches or aggressive driving.

  • Aftermarket Options: Look for aftermarket axles specifically designed for high horsepower applications.
  • Material Strength: Choose axles made from high-strength materials to withstand the increased loads.
  • CV Joints: Consider upgrading to stronger CV joints for improved reliability and performance.

Differential Upgrades

The differential plays a critical role in transferring power to the wheels. With a 650 HP LS swap, it is vital to upgrade the differential to handle the increased power and provide better traction.

  • Type of Differential: Consider switching to a limited-slip differential (LSD) for improved traction and performance during acceleration.
  • Gear Ratio: Upgrading to a suitable gear ratio can enhance acceleration while maintaining optimal RPMs on the highway.
  • Strength: Look for a differential housing that can withstand the power output of your LS engine.

Conclusion

Supporting mods such as upgraded driveshafts, axles, and differential upgrades are essential for a successful 650 HP LS swap in a 240SX. These modifications not only enhance performance but also ensure the reliability and safety of your vehicle. Investing in quality components will provide peace of mind and allow you to enjoy the full potential of your LS-powered 240SX.
