Overview

The SuperPro Rear Trailing Arm Upper & Lower Bushing Kit is designed to enhance the handling, stability, and overall ride quality of your Mazda RX-7 GS and other compatible models from the late 1970s to mid-1980s. This high-quality suspension upgrade is ideal for enthusiasts looking to restore or improve their vehicle's performance, whether for daily driving, spirited street use, or track days.

Manufactured by SuperPro, a trusted name in suspension components, this bushing kit replaces worn or degraded factory bushings with durable, performance-oriented polyurethane. The result is improved suspension response, reduced unwanted movement, and a more precise steering feel, helping you get the most out of your classic Mazda.

Key Features

SuperPro's Rear Trailing Arm Bushing Kit offers several technical advantages designed to optimize your vehicle's suspension performance:

  • Constructed from high-grade polyurethane material that resists wear, cracking, and deterioration over time, ensuring long-lasting performance and reliability.
  • Precisely engineered to match the factory geometry, providing a direct bolt-on upgrade without the need for modifications.
  • Reduces unwanted suspension movement and flex, which can improve handling and cornering stability during spirited driving or track use.
  • Helps restore factory ride quality by eliminating excessive play in the rear suspension components.
  • Designed to withstand harsh conditions, including exposure to oils, chemicals, and road debris, maintaining performance over the vehicle's lifespan.
  • Manufactured with precision to ensure proper fitment and ease of installation, making it suitable for DIY enthusiasts and professional mechanics alike.
  • Ideal for restoring the original handling characteristics or upgrading for more aggressive driving styles.

Construction & Design

The SuperPro bushing kit features a one-piece polyurethane construction that offers a significant upgrade over traditional rubber bushings. The polyurethane material provides a firm yet compliant feel, reducing deflection and enhancing suspension responsiveness. The bushings are precisely molded to fit the OEM trailing arm components, ensuring a perfect fit and alignment.

The design incorporates advanced engineering techniques, including CAD development and rigorous testing, to ensure durability and performance consistency. The bushings are easy to install with standard tools and do not require any special modifications or pressing equipment, making them a convenient upgrade for your Mazda RX-7 or compatible models.

Installation & Fitment

The SuperPro Rear Trailing Arm Bushing Kit is a straightforward bolt-on upgrade that requires no cutting, drilling, or complex modifications. The kit is designed to fit directly into the factory trailing arms of the specified Mazda models, restoring or enhancing suspension performance with minimal effort. Basic mechanical skills and standard hand tools are sufficient for installation, and a professional alignment is recommended afterward to ensure optimal handling.

  • Easy, bolt-on installation with no need for specialized tools or equipment.
  • Replaces worn or degraded factory bushings to restore original handling and ride quality.
  • Suitable for both restoration projects and performance upgrades.
