Show original supplier description
The Cloyes 9-3125A is a high-performance engine timing set engineered for superior durability and precise valve timing control. This set features CAD-designed components manufactured using premium materials, ensuring that each part is tested and measured for function, fitment, and longevity. The kit includes camshaft sprockets and crankshaft sprockets, both heat-treated for enhanced durability. The crankshaft sprocket is equipped with three keyways, allowing for advance or retard of valve timing to fine-tune engine performance. It also features a true roller .250 diameter chain and is hand-matched at the factory to guarantee proper center distance. These complete kits meet or exceed OEM performance requirements, providing a quiet and maintenance-free experience for your engine’s valve train. This timing set is specifically designed for Chrysler, Dodge, and Plymouth vehicles, with detailed fitment available for numerous models from 1958 through 1978. The Hex-A-Just® feature on the camshaft sprocket hub allows for infinitely adjustable timing, enabling precise fine-tuning. Installation requires specific tools, including hex bit sockets and a torque wrench, as well as supplies like assembly lube and thread locking compound.
