Cusco Pillowball Rear Trailing Arm Bushings

2011–2025 Mitsubishi Lancer Evolution 4/5/6/7/8/9 (CT9A) 560 464 EV

Part #: 560 464 EV

Overview

The Cusco Pillowball Rear Trailing Arm Bushings are a high-performance upgrade designed specifically for Mitsubishi Lancer Evolution models from the fourth to the ninth generation, including the CT9A chassis. These bushings are engineered to enhance your vehicle's suspension response, providing a more precise and confident driving experience whether you're on the street or at the track. Crafted with racing-grade pillow balls, these bushings eliminate the flex and deflection common with stock rubber components, ensuring your suspension performs at its peak during spirited driving and aggressive cornering.

Ideal for enthusiasts seeking improved steering response, straight-line stability, and consistent handling, the Cusco pillowball bushings help you maintain better control and confidence in demanding driving conditions. Their robust construction and high-precision design make them a reliable choice for those who push their Mitsubishi Lancer Evolution to its limits while maintaining durability and longevity.

Key Features

The Cusco Pillowball Rear Trailing Arm Bushings incorporate several advanced features that set them apart from standard rubber bushings:

• High-precision pillow balls made from durable materials, often used in racing vehicles, to provide maximum rigidity and responsiveness.
• Elimination of compression and deflection, allowing the suspension to react more directly to driver inputs and road conditions.
• Strengthened suspension joints that reduce alignment changes during aggressive driving, helping to maintain optimal tire contact and handling characteristics.
• Rubber boots included to protect the pillow balls from dirt, debris, and moisture, ensuring consistent performance and extended service life.
• Designed to withstand the rigors of high-performance driving while maintaining a high level of reliability and durability.
• Constructed with high-quality materials that resist wear and deformation, even under demanding conditions.
• Engineered to improve steering response, cornering accuracy, and straight-line stability, making your Evo more predictable and responsive.
• Compatible with stock suspension components, offering an easy bolt-in upgrade without the need for extensive modifications.
• Suitable for both daily driving enthusiasts and competitive racers looking to maximize suspension performance.

Construction & Design

The Cusco pillowball bushings are meticulously designed with a focus on performance and durability. The core component is the high-precision pillow ball, which replaces the softer rubber or polyurethane stock bushings. These pillow balls are crafted from hardened steel or similar materials to withstand the stresses of aggressive driving and racing conditions. The bushings are housed within a robust metal or composite casing that ensures a secure fit and optimal alignment.

The inclusion of rubber boots serves a dual purpose: protecting the pillow balls from dirt, mud, and moisture, and maintaining consistent performance over time. The design minimizes unwanted movement and deflection, translating to sharper steering and more predictable handling. The bushings are engineered with precise tolerances, ensuring a perfect fit and seamless integration with your vehicle's suspension system.

Performance & Sound

By replacing the factory rubber bushings with Cusco's pillowball units, you'll notice an immediate improvement in steering response and cornering precision. The increased rigidity reduces unwanted suspension flex, allowing your Mitsubishi Lancer Evolution to respond more directly to driver inputs. This upgrade also enhances straight-line stability, especially at high speeds or during aggressive acceleration.

While these pillowball bushings are primarily focused on performance and handling, they may produce a slightly firmer ride and increased noise compared to stock components. However, this trade-off is common among high-performance suspension upgrades and is generally appreciated by enthusiasts seeking maximum control and feedback.

Installation & Fitment

The Cusco Pillowball Rear Trailing Arm Bushings are designed as a direct bolt-in replacement for the factory bushings on Mitsubishi Lancer Evolution models from 4G63 to 9G63 (CT9A). Installation typically involves removing the rear trailing arms from the vehicle and pressing out the stock bushings before installing the pillowball units. No cutting, drilling, or extensive modifications are required, making this a straightforward upgrade for experienced DIY enthusiasts or professional mechanics.

It is recommended to perform an alignment after installation to ensure optimal handling and tire wear. For best results, pairing these bushings with other suspension upgrades can further enhance your vehicle's performance characteristics.
