Product Details

The QA1 MD301-08600 is a Mustang II Pro Coil Front Coilover Conversion System designed for street rod, performance, and racing builds using the popular Mustang II front suspension platform. This kit replaces the factory shock and coil spring setup with a purpose-built coilover unit, delivering dramatically improved handling, a lower stance, and a high degree of tuning flexibility.

At the heart of this system are double-adjustable twin-tube shocks with 324 valving selections, allowing precise independent compression and rebound tuning to dial in the exact ride characteristics needed for your application. The fully threaded shock body allows up to 3.0 inches of ride height lowering, giving builders the ability to fine-tune stance and front-end weight balance without compromising suspension travel.

Key Features:

  • Double-adjustable valving with 324 total compression and rebound settings
  • 600 lb/in spring rate — suited for 1,525–1,700 lb front-end weight
  • Chrome-plated coilover springs, 8 in. length, 3.50/2.50 in. I.D., designed specifically for the Mustang II spring pocket
  • Stud upper / eyelet lower shock mounting configuration
  • 1/2 in. ID lower bolt hole with bearing mount
  • Fully threaded shock body for 0–3.0 in. of ride height adjustment
  • Longer spring design for increased suspension travel and improved ride quality
  • Sold as a pair (front, left and right)
  • Backed by QA1's Limited Lifetime Warranty

This system is well-suited for drag racing, autocross, road racing, street performance, and street rod builds. QA1 Pro Coil Systems are also available in Steel Economy, Single Adjustable, and "R" Series configurations to match any build budget or performance goal.

AT THIS TIME "GREAT TRANSACTION"

Everything arrived well packaged and in good order... It was shipped promptly, but hey, no accounting for the snow storm in the NW... I think UPS calls it an "act of God"... Thanks

good

Was nice and easy just wish there was a better product picture and more info.

First time I've tried these guys. Had trouble getting this product from my normal source (backordered) but Autoplicity shipped quickly and had a better price too! You know I will be back! Thanks!

Great shopping experience have ordered from autoplicity several times. Only downfall is they don't offer free shipping but usually the price plus shipping is less than anywhere else.

Quick

Quick and easy checkout THANKS

The order process was fast and easy. I was able to determine the part I wanted with the help of their sales department. I purchased my H&R lowering springs for less then I could find anywhere else and I also got a great deal on my EBC Green Stuff brake pads. The following day however i noticed a descrepency in my shipping address in the confirmation e-mail they sent me. After being dicsconnected multiple times and at least 6 seperate attempts to reach the shipping department i was finally connected and assured that the information that they had was correct. It did seem like a waste of 45 minutes but at least I know that the parts are going to be delivered to the correct address.
