KONI has been in business for 150 years, involved in automobile dampers since 1932 and has produced adjustable telescopic dampers since 1945. In addition, though known best for cars, KONI also builds shocks for trucks, buses, RVs and railway rolling stocks as well. What this adds up to is well-earned design and manufacturing experience.

As the maker of the industry's very first adjustable shock absorber, electronic drag racing shocks and today's patented FSD street shocks, KONI has demonstrated that product improvement means product innovation.

As a niche maker of high-performance shocks, KONI is small enough to interact with its customers on a regular basis, even having a Tech line staffed every working day with KONI technicians, many of whom are car enthusiasts just like you. What this means is that you receive the personal attention missing in most product businesses today.



A popular combination with the Koni FSD Shocks is the addition of the Eibach Pro Kit Lowering Springs
