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 center 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 - Cloyes and Quick Adjust®!
