Superpro Duroball Kit

2001–2008 Mitsubishi Evo 7/8 and 9 Front Lower Control Arm Bushings

Part #: DURO3739K

Overview

The SuperPro Duroball Kit is a high-performance upgrade designed specifically for Mitsubishi Evolution models from 2001 to 2008, including Evo 7, 8, and 9. This kit replaces the factory front lower control arm bushings with a precision-engineered hybrid assembly that enhances steering response, handling, and overall vehicle control. Whether you're a spirited street driver, a track enthusiast, or an off-road adventurer, these bushings are built to deliver improved articulation and NVH (noise, vibration, harshness) characteristics, providing a more connected and confident driving experience.

Engineered for demanding applications, the Duroball Kit offers a significant upgrade over stock bushings by combining the durability of a metal spherical bearing with the flexibility of high-quality polyurethane. This combination ensures precise control of suspension geometry while minimizing unwanted movement and deflection. As a result, you'll experience more accurate steering feedback, sharper turn-in, and enhanced stability during aggressive driving or cornering.

Key Features

The SuperPro Duroball Bushings incorporate advanced materials and innovative design features to optimize performance and longevity. Key features include:

• Hybrid metal and polyurethane construction for superior articulation and durability under demanding conditions.
• Metal spherical bearings that provide precise movement and reduce deflection compared to traditional rubber bushings.
• High-quality polyurethane that offers excellent NVH characteristics, reducing unwanted noise and vibrations while maintaining firm suspension response.
• All components are engineered to fit directly into the factory mounting points, ensuring a straightforward installation process without modifications.
• Designed to withstand harsh driving environments, including spirited street driving, autocross, and track use.
• Improves steering precision, handling, and overall suspension performance for a more confident driving experience.

Construction & Design

The SuperPro Duroball Kit features a robust hybrid design that combines the strength of metal spherical bearings with the flexibility of premium polyurethane. The metal components are crafted from durable, corrosion-resistant materials, ensuring long-lasting performance even under extreme conditions. The polyurethane bushings are formulated to provide a balance between stiffness and compliance, helping to reduce NVH while maintaining precise suspension control. The one-piece design ensures consistent articulation and reduces the risk of bushing deformation or failure over time. CAD-developed and TIG-welded for precision fitment, these bushings are built to meet the rigorous demands of performance driving.

Installation & Fitment

The SuperPro Duroball Bushings are designed as a direct bolt-in replacement for the factory front lower control arm bushings on Mitsubishi Evo 7, 8, and 9 models from 2001 to 2008. No cutting, drilling, or extensive modifications are required. The installation process is straightforward for those familiar with suspension work, and all necessary hardware is included. For optimal results, it is recommended to have a professional alignment after installation to ensure proper suspension geometry and handling characteristics.
