Overview

It features SAE 1144 billet steel sprockets and a true roller timing chain.

Show original supplier description

This premium race component features a double roller chain matched with sprockets made from SAE 1144 induction heat-treated, billet steel, ensuring superior strength and longevity for demanding applications. The standout feature of this set is the patented Hex-A-Just system, offering infinitely adjustable camshaft timing from +/- 6 degrees. This allows for fine-tuning engine performance to precise specifications, saving valuable setup time. The set includes a 3-keyway adjustable crankshaft sprocket and is designed to be 0.005 inches shorter than standard for specific fitment. Installation involves preparing the engine by ensuring all components are clean and rotating parts are free. The Hex-A-Just fuel pump eccentric is installed onto the camshaft sprocket, allowing for precise timing adjustments. While a degree wheel is recommended for optimal accuracy, a simpler installation method is also described. Proper lubrication and torquing of the camshaft sprocket mounting bolt to 40-45 ft-lb are crucial for durability. The instructions also note that the new camshaft sprocket may have an integrated spacer, and any old spacer should be discarded. Cloyes has a long history in timing components, dating back to the early 1920s, and revolutionized the race industry with their True Roller Timing system in 1970. This Hex-A-Just set represents their commitment to providing quality, performance-oriented timing drives for racers and enthusiasts.
