Construction & Design

The SPC Performance xAxis Bushing Upgrade Kit features a robust construction that combines precision-machined components with high-quality rubber and nylon materials. The core of each joint is a free pivoting inner ball, which allows for maximum articulation and droop travel, essential for off-road and aggressive driving scenarios. The bushings are bonded with a rubber outer shell that helps absorb vibrations and noise, ensuring a smooth and quiet ride comparable to factory standards.

The kit includes a specialized press tool, making installation straightforward even for DIY enthusiasts. The design emphasizes durability and longevity, with components built to withstand harsh conditions and repeated movement. The use of high-grade materials ensures that the bushings maintain their shape and performance over time, providing consistent handling and suspension response.

Performance & Sound

Upgrading to the SPC xAxis bushings significantly improves suspension responsiveness, allowing your vehicle to better absorb bumps and maintain tire contact with the road or trail. The free pivoting design enhances droop travel, which is particularly beneficial during off-road excursions or spirited driving on uneven surfaces. While specific horsepower or torque gains are not applicable, users can expect a noticeable improvement in handling precision, steering feel, and overall suspension control.

The design maintains factory NVH levels, so you won't experience increased noise or vibrations, making this upgrade suitable for daily driving as well as performance applications.

Installation & Fitment

The SPC Performance xAxis Bushing Upgrade Kit is a bolt-on solution that requires no cutting, drilling, or modifications to your vehicle. The included press tool simplifies the installation process, allowing you to replace the bushings in your existing suspension arms with minimal effort. Basic mechanical skills and standard tools are sufficient for installation, but professional alignment is recommended afterward to ensure optimal handling and tire wear.

Installation typically involves removing the suspension arms from your vehicle, pressing out the old bushings, and pressing in the new xAxis joints using the provided tool. The process is straightforward and designed to restore your suspension's factory geometry while enhancing its capabilities.
