Make quick and precise cam timing changes with no troublesome offset bushings or keyways. Torrington thrust bearings reduce friction between the block and cam sprocket. Most sets are offered with . 005" or . 010" reduced center distance. An industry breakthrough when introduced in 1992. Since then the accuracy and simplicity of our Hex-A-Just(R) system has been unmatched by our competitors. The Hex-A-Just(R) True(R) 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(R) 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(R) will get you there fast!
Cloyes was founded in the early 1920s in Cleveland, Ohio, by Raymond Cloyes, who started the business by manufacturing by hand a small quantity of replacement fiber and aluminum timing gears for trucks and automobiles. Thus began the story of Cloyes Gear Works, now known as Cloyes Gear and Products, Inc. Cloyes was the first to offer a line of replacement timing components to fit essentially any product with an internal combustion engine. In 1970, Cloyes revolutionized the race industry with the development and introduction of the very first True Roller Timing system. Cloyes has been manufacturing quality timing drives and components since the 1920's. Cloyes offers something for every level of racer. Cloyes offers Cloyes Heavy Duty Timing Chain Sets and Cloyes Street True Roller sets for budget minded racers.
