HARDRACE Rear Upper Control Arm Bushing – Mitsubishi Lancer Evolution 4/5/6/7/8/9

Description

HARDRACE Rear Upper Control Arm Bushing – Mitsubishi Lancer Evolution 4/5/6/7/8/9

Firstly, BUY HARDRACE Rear Upper Control Arm Bushing for Mitsubishi Lancer Evolution 4–9. Upgrade the rear suspension of your Mitsubishi Lancer Evolution with the HARDRACE Rear Upper Control Arm Bushing for Evo 4/5/6/7/8/9. Designed for the CN9A, CP9A, and CT9A Evolution platforms, this HARDRACE suspension bushing provides a direct replacement solution for worn original rear upper control arm bushings. HARDRACE lists the application for Evolution IV, V, VI, VII, VIII, and IX models.

The rear upper control arm bushing plays an important role in controlling suspension movement and maintaining a consistent connection between the control arm and chassis. As factory rubber bushings age, they can become worn or excessively compliant, allowing additional movement in the rear suspension. Replacing these components can help restore a more controlled and predictable suspension response.

HARDRACE offers this application in two configurations: hardened rubber and pillow ball. The hardened rubber version is Part Number 6656, while the pillow ball version is Part Number 6657. Both are listed as 4-piece sets for the rear suspension of compatible Evo 4–9 models.

HARDRACE 6656 – Hardened Rubber

The HARDRACE 6656 uses hardened rubber construction and is designed as a durable replacement for the original suspension bushing. HARDRACE describes its hardened rubber products as high-strength components designed to provide improved suspension feel and resistance to cracking. The 6656 is supplied as a 4-piece set.

HARDRACE 6657 – Pillow Ball

The HARDRACE 6657 uses a pillow ball/spherical bearing design. It is also supplied as a 4-piece set and is designed to provide more direct suspension movement, improved driver feedback, and increased response compared with a conventional rubber bushing.

Important: 6656 and 6657 are different products. Select the correct version according to your intended use and the exact product you are purchasing.

Improve Rear Suspension Control

The rear upper control arm helps position and control the rear suspension. Its bushings allow controlled movement while isolating unwanted vibration and movement from the chassis.

Firstly, replacing worn bushings can help restore the original relationship between the control arm and its mounting points.

Secondly, a firmer bushing can reduce unwanted compliance and provide more consistent suspension response during cornering, braking, and acceleration.

Thirdly, the choice between hardened rubber and pillow ball allows you to tailor the upgrade to your vehicle. Hardened rubber provides a more traditional bushing solution, while pillow ball construction provides a more direct connection and greater suspension feedback.

For a modified Evo, these bushings can also be used as part of a broader rear suspension refresh alongside control arms, trailing arm bushings, toe arms, dampers, and alignment components.

Hardened Rubber vs. Pillow Ball

6656 Hardened Rubber

HARDRACE 6656 is the hardened rubber version. It is supplied as a 4-piece set and is intended for owners who want a stronger, more durable replacement bushing while retaining a rubber-style suspension connection.

This configuration can be suitable for street-driven Evo 4–9 models and performance builds where durability and improved suspension control are priorities.

6657 Pillow Ball

HARDRACE 6657 is the pillow ball version. It uses a spherical bearing design intended to provide a more direct suspension connection, increased feedback, and precise control. It is also supplied as a 4-piece set.

This configuration is more performance-focused and can be appropriate for vehicles where direct suspension response and feedback are important.

Installation

Installation requires removal of the original rear upper control arm bushings and installation of the HARDRACE replacements. Because suspension bushings can require specialized pressing equipment, professional installation is recommended unless you have the appropriate tools and experience.

After installation, inspect the surrounding suspension components for wear or damage. A wheel alignment should also be considered after suspension components have been removed or replaced, particularly if the vehicle’s suspension geometry has been disturbed.

Always verify the correct HARDRACE part number before installation.

HARDRACE 6656
