What makes the 'X4' designation different from a standard axle?

The X4 designation indicates an updated internal design featuring four cage bearings within the CV joint. This setup helps to better distribute the load and reduce internal friction, allowing the axle to handle higher horsepower and torque loads more effectively than traditional designs.

Does this axle come with all the necessary hardware for installation?

This axle is designed as a direct replacement and typically includes the axle shaft and CV joints. However, it's recommended to refer to the manufacturer's installation instructions or contact us to confirm if any specific hardware, such as new axle nuts or seals, are included or recommended for purchase separately.

What kind of maintenance is recommended for high-performance axles?

Proper maintenance involves ensuring the CV boots remain intact and free from tears or punctures, as this protects the internal grease and bearings. Regular inspections for any signs of grease leakage or damage are important. Always use the specific type of grease recommended by the manufacturer during installation or any service.

About this part

Product Details

This is the Driveshaft Shop 700HP X4 axle for the left side of your 2012-2015 Honda Civic Si. If you're pushing significant power through your Si, especially with modifications that raise horsepower well beyond stock, a stronger axle is essential to handle the increased torque and stress. This axle is built to withstand up to 700 horsepower, offering a robust solution for performance-oriented builds.

The X4 designation means this axle features an updated design with four internal cage bearings, which helps distribute load more evenly and reduces internal friction compared to traditional designs. This improved internal geometry is key to its higher power handling capability. The axle shaft itself is constructed from strong, heat-treated alloys, and the outer CV joint is also beefed up to match the increased power. It's designed as a direct replacement for the factory left-side axle, meaning it fits right into your existing drivetrain setup without requiring major modifications, assuming your vehicle's mounting points are in good condition.

When installing a high-performance axle like this, it's important to ensure all related drivetrain components are also in good shape. Check your differential, transmission, and wheel bearings for any signs of wear. Proper installation, including using the correct grease and ensuring the axle seats fully, is crucial for its longevity and performance. This axle is a solid option for Civic Si owners looking to reliably put down more power.
