Cloyes introduced the very first True® Roller Timing Set in 1970,
and has led the timing industry in quality and innovation ever
since. Sprockets are made from SAE D7003 ductile iron or
induction hardened cast iron for unmatched durability. The
Renold True® Roller chain features full roller action and superior
strength. Rollers are made from high strength steel, which is
rolled and hardened to exacting standards. This Original True®
Roller Set remains the benchmark against which all others are
measured.
Original True® Roller Sets feature:

• Ductile Iron, or Induction Hardened Cast Iron Cam Sprocket
• Renold True® Roller Chain with .250 Diameter Rollers
• Billet Steel, Induction Hardened Crank Sprocket with 3 Keyway’s, Plus or Minus 4 degrees
• Sets Matched at the Factory to Assure True Center Distance
