These kits provide the highest quality performance characteristics for your Mustang II front end. The springs are designed specifically for use with the QA1 coil-over shocks and the factory upper spring pocket. This enables the use of a longer spring, which allows for a lighter overall spring rate. By building the upper section of the spring to factory dimensions, this puts the weight back into the frame instead of on a single stud. 

  • Single (rebound) adjustable valving
  • Billet aluminum body 
  • Developed for high performance with increased travel
  • Unique piston rod design provides shorter compressed height to allow lower car ride height
  • Easy bolt-in installation
  • Includes 2 shocks, mounting kit, 2 chrome-plated springs (choose specific rate)

NOTE: Not recommended for front axle weights in excess of 1900 lbs.
