• Vibration Damping: While stiffer than rubber, these bushings are engineered to absorb road vibrations effectively, maintaining a comfortable ride quality.
• Corrosion Resistance: The polyurethane material resists oil, grease, and other automotive fluids, preventing degradation over time.
• Precision Fit: Designed specifically for the 2005–2008 Subaru Outback XT, ensuring a straightforward installation with factory-like fitment.
• Improved Tire Life: By maintaining proper suspension geometry, these bushings help reduce uneven tire wear and extend the lifespan of your tires.
• Easy Installation: The kit includes all necessary components and hardware for a hassle-free replacement process, making it suitable for both DIY enthusiasts and professional mechanics.

Construction & Design

The SuperPro Rear Control Arm Upper-Inner Bushing Kit features a robust polyurethane formulation that balances stiffness and durability. The bushings are precisely molded to match OEM specifications, ensuring a perfect fit and reliable performance. The design incorporates a one-piece construction that minimizes movement and flex, providing a stable connection between the control arm and chassis.

Manufactured with advanced CAD modeling and TIG welding techniques, these bushings are engineered to withstand the rigors of daily driving, spirited cornering, and off-road adventures. The high-quality materials resist cracking, splitting, and deformation, even under extreme conditions, making them an excellent upgrade over worn-out rubber bushings.

Performance & Handling

Replacing your vehicle’s worn control arm bushings with SuperPro's polyurethane components significantly enhances handling precision and steering feel. The reduced flex in the suspension improves wheel alignment consistency, leading to more predictable and responsive steering. This upgrade is especially beneficial for drivers who enjoy spirited driving, autocross, or off-road excursions, where suspension stability is critical.

While these bushings are stiffer than rubber, they are designed to deliver a balanced ride that maintains comfort without sacrificing performance. The improved suspension geometry helps support better tire contact with the road, resulting in improved traction, cornering confidence, and overall driving enjoyment.

Installation & Fitment

The SuperPro Rear Control Arm Upper-Inner Bushing Kit is a direct replacement for the factory bushings on the specified model years. Installation typically involves removing the control arm from the vehicle, pressing out the old bushings, and pressing in the new polyurethane units. No cutting, drilling, or complex modifications are required, making this a straightforward upgrade for experienced DIYers or professional technicians.

For optimal results, it is recommended to perform a wheel alignment after installation to ensure proper suspension geometry and tire wear. The kit includes all necessary hardware and instructions for a complete and secure fitment.
