Product Details

The QA1 Pro Coil Single Adjustable Mustang II Coilover Shock Assembly is a complete coilover spring and shock assembly built for Mustang II-style front suspensions. It combines a performance coil spring and a single adjustable shock in one unit. It suits street rods, classic restorations, muscle cars, and custom street and track builds.

Key Features:

  • Single adjustable damping: Lets you adjust shock valving to suit your vehicle, driving style, and conditions.
  • Coilover design: Combines the spring and shock in one assembly, which gives a cleaner installation and improved control over ride quality.
  • Adjustable ride height: Threaded spring seat adjustment allows ride height and preload to be fine-tuned.
  • Precision construction: Built from durable, machined components for consistent performance and long service life.
  • Mustang II application: Designed for Mustang II-style front suspension setups commonly used in aftermarket and custom chassis.

QA1 Precision Products is a well-known American manufacturer of suspension components for street, strip, and track. The Pro Coil line is designed to improve handling, ride quality, and tunability. Multiple configurations are available to match different spring rates and vehicle requirements.
