Cloyes patented Quick Adjust True Roller Speed Sets keep you ahead of the competition by offering a new way to adjust cam timing up to +/- 6 degrees. Just loosen the six bolts around the cam sprocket, insert the patented Quick Adjust tool, and tune your way to faster times. Sprockets are machined from premium billet steel on our state-of-the-art CNC equipment. Both sprockets are then induction hardened and oil-quenched using our in-house multi-stage heat treat process.
Our Premium True Roller chain features superior strength with full roller action. Side plates are cut and shaved from high strength steel and heat-treated for maximum fatigue resistance. The .250" rollers are "cold rolled" and hardened to exacting standards increasing load and RPM capabilities. All Quick Adjust sets are hand-matched at our manufacturing facility to qualify centre distance and run-out. An additional feature on Chevrolet applications is the Cloyes patented "cheater" sprocket tooth profile that provides improved chain wrap and smoother transition. Get serious about going fast with this unbeatable combination.
