Powerflex Rear Trailing Arm Bush (Set of 4)

This kit comprises four high-performance polyurethane trailing arm bushes from Powerflex, a recognised leader in the field of vehicle suspension enhancement. These bushes are designed as a direct replacement for the original rubber components fitted to your vehicle’s rear trailing arms, offering substantial improvements in handling characteristics and long-term durability.

Trailing arms play a critical role in maintaining correct wheel alignment during cornering and over uneven road surfaces. The factory rubber bushings, while adequate for standard driving conditions, can degrade over time due to exposure to the elements, road salt, and general wear and tear. This degradation leads to increased suspension deflection, imprecise handling, and ultimately, compromised safety. Powerflex bushes address these issues by utilising a specifically formulated polyurethane compound.

Key Features & Benefits:

• Material Composition: Powerflex utilises a proprietary polyurethane blend engineered for superior performance compared to traditional rubber. This material exhibits significantly higher resistance to compression set (permanent deformation), oil contamination, and general deterioration.
• Enhanced Handling Precision: By reducing the amount of flex within the trailing arm mounting points, these bushes provide a more direct connection between the suspension components and the chassis. This translates into improved steering response, reduced body roll, and increased stability during cornering.
• Increased Durability & Longevity: Polyurethane is inherently more durable than rubber, resisting cracking, splitting, and premature wear. Powerflex bushes are designed to withstand demanding driving conditions and offer a significantly extended service life compared to OEM components.
• Improved Load Control: The stiffer nature of the polyurethane material helps maintain consistent wheel alignment under varying load conditions, such as when carrying passengers or luggage.
• Compatibility & Fitment: These bushes are specifically designed for direct replacement within the original trailing arm housings, ensuring a straightforward installation process. Please verify compatibility with your vehicle’s make and model before purchase.

The benefits of upgrading to Powerflex rear trailing arm bushes extend beyond purely performance-related aspects. Replacing worn rubber bushings can also contribute to improved ride comfort by minimising unwanted suspension movement and vibrations. While polyurethane is stiffer than rubber, the precision of the design and material properties help to transmit road forces more effectively, leading to a feeling of increased control without sacrificing overall comfort.

Understanding Bush Durometer: Powerflex offers bushes in various durometers (hardness levels), denoted by colour coding. This particular kit is generally supplied in their standard 'Purple' compound – offering a balance between performance and compliance for road use. This provides a noticeable improvement over worn rubber without introducing excessive harshness. For more focused track day applications, harder compounds ('Black') are available separately.

Installation Considerations: While designed for direct replacement, installation may require specialist tools and knowledge. It is recommended that the bushes be fitted by a qualified mechanic experienced in suspension work. Correct torque settings must be adhered to during installation to ensure optimal performance and longevity.

Complementary Upgrades: For maximum benefit, consider pairing these rear trailing arm bushes with other Powerflex suspension components, such as front control arm bushes, anti-roll bar mounts, and engine/gearbox mounts. These upgrades work synergistically to create a cohesive and highly effective suspension system.
