An industry breakthrough when introduced in 1992. Since then the accuracy and simplicity of our Hex-A-Just® system remains unmatched by competitors. The Hex-A-Just® True® Roller Set is infinitely adjustable to /- 6 degrees. No machining required and no fumbling with offset bushings. Simply dial in your cam timing with the turn of a wrench then tighten the cam bolts to lock the cam position in place.
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. An additional feature on Chevrolet applications is the Cloyes’ patented “cheater” sprocket tooth profile that provides improved chain wrap and smoother transition.
