Riaction Coilovers

Riaction supplies and customizes various suspension parts exporting worldwide, including Japan and USA.

In 2015, with our unique knowledge in suspension and technical support from a very experienced company in Japan, we started to provide high quality coilover kits with our own brand, “RIACTION”.

Unlike other brands, Riaction Sports Coilover Kit is truly designed for street vehicles, including daily-driving cars and provides satisfying comfort with better handling and better looks.
