High Performance


An industry breakthrough when introduced in 1992, the Cloyes Hex-A-Just True Roller Timing Set is the industry standard in adjustable cam timing. Since then, the accuracy and simplicity of the Cloyes Hex-A-Just True Roller Timing Set system has been unmatched by Cloyes competitors.

  • The Hex-A-Just True Roller Set is infinitely adjustable to plus or minus six degrees
  • The Hex-A-Just True Roller Set requires no machining or 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
  • When combined with Cloyes Quick Button™ Two-Piece timing cover, this Cloyes’ patented technology will save you hours of valuable set-up time
  • The Premium Cloyes True Roller chain features superior strength with full roller action. The side plates are made from heat-treated, high strength steel, and the .250” rollers are cold rolled and hardened to exacting standards
  • On Cloyes Chevrolet applications, you also get the Cloyes patented “Cheater” sprocket tooth profile that provides better chain wrap and a smooth transition. Whether your destination is the street or the track, Hex-A-Just will get you there fast
  • 3-Keyway billet crank sprocket
  • All sets are hand-matched at factory to ensure accurate center distance
