Info

These kits provide the highest quality performance characteristics for your Mustang II front end. The unique "half barrel" shape springs are designed specifically for use with the included 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. 

  • For stock-to-2" lowered cars (no less)
  • Fixed, non-adjustable valving 
  • Developed for high performance with increased travel
  • Fully adjustable ride height using included aluminum spanner nut
  • Easy bolt-in installation
  • Unique spring fits the stock upper seat in the frame
  • Includes 2 chrome body shocks, mounting kit, 2 chrome-plated springs (choose specific rate)

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

Item Details

Includes 2 shocks and 2 springs.

Notes

  1. Can be installed with no special tools, and delivers the ride characteristics of "other" coil-overs. 
  2. This is a true bolt-on coil-over kit for all specialty cars using Pinto/Mustang II based front suspensions. Kits work with stock or aftermarket crossmembers and upper control arms, stock lower control arms or tubular replacements will work also. Some fitting required.
