For over 65 years Tokico has been making automotive shock absorbers, brake parts and hydraulics. They are a principal OEM, as well as aftermarket manufacturer. Tokico has developed their shock absorbers specifically to deal with the problem of providing handling stability with a comfortable ride. In response to this, Tokico designed the first twin-tube gas shock absorber in the 1970s. Tokico has continued to advance and perfect this technology, and it remains a standard of performance shock absorber design around the world. Firmly rooted in the OEM market and their cutting-edge manufacturing processes, Tokico logically progressed to open a High Performance division. Tokico opened its first aftermarket office in California in 1979. Tokico follows its creative R&D process and designs all of its High Performance products to be specific to a particular vehicle. Most of their products are protected by a lifetime limited warranty. Tokico's dedication and experience strengthened them as a premier aftermarket manufacturer of performance shocks and struts. Tokico's global headquarters are in Kanagawa, Japan and this facility also houses their product research and development facilities. In Berea, Kentucky, Tokico produces high quality OEM parts for major auto manufacturers. The office for OEM sales and engineering is in Allen Park, Michigan and the Tokico High Performance sales division is located in Los Angeles, California, the center of the aftermarket world. Tokico and Hitachi merged in 2004. Tokico's OEM and High Performance products are growing steadily, as well as Private Brand Business and they are positioned to continue as the premier company in the worldwide automotive suspension industry.
