Dont 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 24 valving options and two coil 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

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