Testing Testing and Development Throughout its 99-year history, Cloyes has developed an unmatched product portfolio by bringing industry-leading timing system products to life through a disciplined research and development approach. The Cloyes engineering and product development team verify all products meet and / or exceed OE specifications by design and problem solve common fail points where possible. Every Cloyes premium race set is hand-matched at the Cloyes facility by trained technicians. This process starts with a detailed component fitment and critical feature analysis. Each set is then measured on a pneumatic matching fixture, allowing rotation of the timing set under a predetermined load to both qualify center distance and control runout. It is this attention to detail that sets Cloyes apart from all competitors. For nearly a century, Cloyes has been building its business and reputation by offering the highest quality timing systems and components. It doesn’t matter what timing system you’re working on, Cloyes has a solution. That’s what we’ve been doing for the past 100 years: providing solutions to your timing needs.
