Cloyes Original true roller timing sets feature full roller-action chains made from high-strength steel for superior durability. The cam sprockets are made from heat-treated cast or ductile iron, while the crank sprockets are machined from heat-treated, high-carbon steel for strength. With three keyways for adjustability (4 degrees advanced, 4 degrees retarded, and normal), Cloyes Original true roller timing sets are hand-matched to ensure precise chain tension.
