The Industry Standard in Adjustable
Cam Timing

An industry breakthrough when introduced in 1992. Since then the accuracy and simplicity of our Hex-A-Just® system has been unmatched by our competitors.  The Hex-A-Just® True® Roller Set is infinitely adjustable to plus or minus six degrees.  No machining required, 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.  When combined with our Quick Button™ Two Piece Timing Cover, this Cloyes’ patented technology will save you hours of valuable set-up time.

Sprockets are made  from SAE 1144 Billet Steel, CNC machined, and then induction hardened to Rc48.  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 our 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!

Note:  All Chevy Sets (non factory roller cam), and BB Chrysler sets include Captured Needle Bearing (#9-220)

All Ford, Oldsmobile and Pontiac Hex-A-Just Speed Sets include a one piece fuel pump eccentric
