Product Details

The QA1 MS303-08600 is a front Pro Coil Single Adjustable coilover spring and shock assembly engineered for the Mustang II suspension platform. Designed for serious performance applications including drag racing, street performance, autocross, road racing, and street rod builds, this system replaces the factory shock and spring combination with a purpose-built coilover unit.

This kit is sold as a pair and includes everything needed for a complete front suspension upgrade. The aluminum shock bodies are lightweight and feature a single-adjustable damping design, allowing tuning of rebound to match your driving style and application. The fully threaded shock body provides ride height adjustability so you can dial in your exact stance.

Key Features:

  • Single-adjustable front coilover shock system with Mustang II upper mount configuration
  • Includes (2) QA1 high-performance aluminum shocks
  • Includes (2) chrome-plated 8-inch coil springs rated at 600 lb/in
  • All mounting hardware included for a complete bolt-in installation
  • Ride height adjustable via threaded shock body
  • 100% dyno tested and serialized at QA1's Lakeville, Minnesota facility
  • Rebuildable and revalveable by QA1 Factory or QA1 Authorized Service Centers
  • Made in the U.S.A.

The QA1 MS303-08600 Pro Coil system is an ideal solution for enthusiasts looking to upgrade front suspension handling and stance on Mustang II-based vehicles. With genuine bolt-in fitment, no cutting or welding is required for a clean, professional installation.

received my order on time. thanks

Fast easy and can use my Amazon card!

Very fast shipping, received it Monday when I ordered it on Thursday. Thanks!

Vera good options

I did receive the parts I ordered in a timely manner. I was not given a confirmation number so I didn't know when to expect my delivery other then that my experience was good.

Ordering was very easy and product was delivered within a week. I ordered a battery and it was received in good condition and works. I would recommend autoplicity to others.

Had to call customer service because I couldn't get paypal to work. He was very helpful and friendly.

Everything went nice and smooth. Thanks.
