Offering 33% more overall strength than the company’s current premium chain, Cloyes’ Z-Series racing timing chain is the most durable and dependable chain available today—and the number-one choice of top professional teams in sprint, circle, track, drag, and off-road racing.

Double-roller Z-Series chains are forged from high-strength steel hardened with a proprietary heat treatment developed by Cloyes. They feature fine-blanked links that reduce severe-load stress fractures and press-fit center links that improve load share and reduce load spikes on any single component.
