Don't you wish you had adjustable coil-overs on the front of your classic car to vary the ride height and road feel? This QA1 Pro Coil Adjustable Front Coil-Over Conversion Kit will do just that for you. You get two adjustable coilover shock assemblies that have a single knob with 12 valving options and two coil springs. 

Choose 350 lb., 450lb. or 550 lb. rate springs.

  • Easy Bolt-In Installation
    • Minimal modifications to be made
    • Remove the existing shocks and springs and the QA1 Pro Coil System bolts right back in.
  • Specialty Designed Conical Springs
    • Springs designed so that the lower end sits on the coil-over shock and the upper end sets in the original spring bucket in the frame
    • Allows for a longer, lighter spring for more stored energy, offering increased weight transfer
    • Greater durability by locating the spring pressure in the frame and not on a single stud
  • Ride Height Adjustable
    • Threaded aluminum body allows easy ride height adjustment
  • QA1 Pro Coil shocks are revalveable and rebuildable by QA1 Authorized Service Centers

What a difference

By 57 150 sedan from Northern Colorado on 5/20/2012
Pros:
Quality stuff
Describe Yourself:
Auto Enthusiast
Bottom Line: Yes, I would recommend this to a friend

I bought these shocks because it seemed like the easiest way to raise the front about an inch which I needed due to the wheel tire combo I am using. I had dropped spindles, dropped springs and a heavy BBC which made it too low, Installing the shocks per the supplied instructions was easy enough. Adjusted the height and then turned the adjustment know 6 clicks, I couldnt believe the handling difference just from a pair of shocks. Hit the railroad tracks at 60 and sail right over, grat stability. Come on Goodguys autocross, here we come.
