Product Details

The QA1 MS301-08600 is a front Pro Coil coilover conversion system designed for the Mustang II front suspension. This single adjustable kit replaces the factory shock and spring setup with a purpose-built coilover unit, delivering significantly improved ride quality, stance, and handling for street performance, drag racing, autocross, road racing, and street rod builds.

The single-adjustable shocks feature a lightweight aluminum twin-tube body with a fully threaded design that enables precise ride height adjustment. The upper shock mount uses a stud configuration and the lower features a bar pin for straightforward installation. Chrome-plated coil springs are rated at 600 lb/in and measure 8 inches in length, providing firm, predictable spring rates ideal for performance driving.

Key Features:

  • Single adjustable valving for tunable rebound damping
  • Aluminum twin-tube shock body — lightweight and durable
  • Fully threaded shock body for ride height and weight-balance adjustability
  • 600 lb/in chrome-plated coil springs, 8" length
  • Stud upper / bar pin lower mounting configuration
  • 100% dyno tested and serialized at QA1's USA facility
  • Rebuildable and revalveable by QA1 or QA1 Authorized Service Centers
  • Sold as a pair — includes (2) shocks, (2) springs, and all mounting hardware
  • Made in the U.S.A.

Suitable for street/strip, autocross, road racing, and hot rod applications where a reliable, adjustable coilover conversion is needed. The bolt-in design simplifies installation while the serialized construction ensures consistent, factory-verified performance.
