Cloyes introduced the very first True® Roller Timing set in 1970 and has led the timing industry in quality and innovation ever since.  Our competitors may say they have a true roller, but only Cloyes has the Original True® Roller.  This Original True® Roller Speed Set remains the benchmark against which all others are measured.

The sprockets are made from SAE D7003 ductile iron or induction hardened cast iron for unmatched durability.  The Premium Cloyes True® Roller chain features full roller action and superior strength.  The high strength rollers are hardened and roller to exacting standards.
