Koni Front Strut, Double Adjustable (pr) ('79-'04)
[KF D/A]

Quick Facts

  • Griggs race winning custom valving
  • Double adjustable configuration so you can easily adjust ride quality or transitional characteristics as required
  • Requires little to no service over an almost indefinite lifespan.
  • Most popular for GR40 cars driven hard on street and road courses, autocross track as well as American Iron and SCCA race cars.

The two most important elements in a performance chassis are the tires and shocks (or struts).  Dampers are a better term as their primary purpose is to dampen motion of the chassis.  So far only Koni provides the quality and performance we demand of dampers to be included in a GR40 Kit.  And then only in units that we have custom built to our specifications. 

Proven by over 50 years of international competition including Formula One, and the only part of our GR40 systems not made in the US, The Dutch company is owned by the US conglomerate, ITT automotive group.  Griggs Racing has worked closely with Koni in developing shocks and struts over the years that do exactly as required in delivering a serious performing chassis while improving handling, traction, ride quality, tire life, and safety.  Also, they live virtually forever with very little service required.  Koni’s are an investment you will have for a very long time.  They are not “throw away” shocks.

Most replacement strut brands on the market usually “feel” pretty good upon replacement but after a short time their “low speed” damping characteristics degrade and handling goes away.  Plus most all are made with inadequate low speed damping for high speed performance, especially on compression. Lesser quality struts are unable to provide the level we seek in offering the best performance in chassis kits and options.  And the adjust-ability is easy, if you follow our instructions. 

With valving perfected to suit our standards, and the win record of GR40 cars to prove the point, these are a necessary step to tuning any 70-04 strut equipped Mustang chassis to perfection.

Special Double Adjustable Damping Curves:  More digressive compression curve and simple on car adjust-ability of rebound makes this the serious club racer’s choice. 

Quickly adjust for track use when high speed control is the main requirement , and then back to street use when the best ride is the priority.

Use with Part Number FCO 2000 coil over hardware Kit, and appropriate camber plate for year of vehicle. Contact us to help you choose from our vast array of springs the correct rate for you.
