Show original supplier description
The Cloyes 9-3167AZ Hex-A-Just True Roller Timing Set is a performance-oriented timing chain kit engineered for GM LS7 and LS9 engines. This kit features a C5R extreme-duty true roller chain with .250-inch diameter rollers, ensuring durability and reliable timing. The Hex-A-Just Z-Racing technology allows for infinite valve timing adjustability of +/-6 degrees (according to AutoZone, though other sources suggest +/-8 degrees from the crank sprocket keyways), enabling precise tuning for maximum engine performance output. The single-piece camshaft sprocket is designed with a 4x cam sensor configuration, compatible with LS3 single-bolt cam sprocket applications. The 3-keyway crank sprocket offers flexibility in setting camshaft timing during engine assembly, with additional sources mentioning 9-keyway crank sprockets for enhanced positioning capabilities. This timing set is specifically designed for GM LS-series engines, including the LS7 and LS9. While predominantly for GM applications, one snippet indicates compatibility with older Chrysler V8s (1956-1990) and V6s (1987-1990) with specific exclusions. The product is described as hand-matched to qualify both center distance and run-out, highlighting Cloyes' commitment to quality control. It is constructed from durable steel to withstand demanding engine conditions.
