SUPLEX GmbH is a medium-sized, owner-managed company based in Willich. It all started in 1992 in a Krefeld warehouse under the company name SUPLEX Fahrwerkstechnik. In 1996, the headquarters in Monchengladbach became too small and was moved to Willich. The expansion continued steadily and so in 2009 another move within Willich was due. At the same time, a change of name took place. SUPLEX Fahrwerkstechnik became SUPLEX GmbH. Our products are 100% OE identical replacement springs for approximately 120,000 different applications.
