Koni Single-Adjustable struts and shocks for the 2011-14 Mustang improve performance while maintaining good ride quality. These single-adjustable dampers have a wide range of rebound adjustment, making them suitable for the lower rates of street-oriented spring sets, as well as the stiffer rates of track-oriented springs.

International Orders


We sell and ship Koni products only to customers within the United States and Canada, as per our Koni distributorship contract. If you are not in the US or Canada, please order from a Koni distributor located within your country.
