Product Details

The QA1 MS301-08500 is a front Pro Coil single-adjustable coilover conversion system engineered specifically for Mustang II suspension applications. Designed for enthusiasts who demand precise ride height control and tunable damping performance, this system replaces the factory shock and spring combination with a purpose-built coilover unit.

The fully threaded shock body allows for ride height adjustment to achieve the exact stance and weight balance you need, whether for street performance or competition use. The single-adjustable valving delivers soft compression and rebound tuning capability, letting you dial in your suspension feel without the complexity of a dual-knob setup.

What's Included:

  • 2 x QA1 single-adjustable Pro Coil aluminum shocks (MS301 series) with 1/2 in. lower eyelet bearing
  • 2 x Chrome-plated 8 in. coilover springs — 500 lb/in spring rate (QA1 P/N 8MB500)
  • All required mounting hardware

Key Features:

  • Single-adjustable damping with 18 damping settings for precise tuning
  • Fully threaded shock body for ride height adjustability
  • Lightweight aluminum shock construction
  • 100% dyno tested and serialized at QA1's Lakeville, Minnesota facility
  • Rebuildable and revalveable by QA1 or QA1 Authorized Service Centers
  • Easy bolt-in installation with supplied hardware
  • Made in the U.S.A.
  • Sold as a pair

Suitable for a wide range of performance disciplines including drag racing, street performance, autocross, road racing, and street rod builds. The QA1 MS301-08500 pairs the proven MS301 shock platform with 500 lb/in chrome-plated springs for a balanced front coilover package ready for Mustang II suspension conversions.

Fast and easy

Good internet layout! very easy to find and to order.

The price is right but shipping cost is high. I bought a transmission seal for $12.91 and shipping was $13.31. The box it shipped in was about 10 times bigger than the part itself. Reduce the box and reduce my shipping cost please ! Else than that the part was in good condition, it was packed right and shipping time was reasonable.
