True Roller Timing Set

The Cloyes 9-3127 Original True Roller Set is engineered to provide a reliable and durable timing drive solution for specific Jeep 4.0L engines from 1964-1993. Cloyes emphasizes that all their products are extensively tested and verified to meet OE specifications, ensuring proper function, fitment, and longevity. The construction utilizes materials like SAE D7003 ductile iron for the sprockets and billet steel induction hardening for the crank sprocket, contributing to the overall strength and wear resistance of the components. The "Original True Roller" designation highlights its construction and intended use. Installation notes indicate that this timing set has 3 keyways, which allow the installer the ability to retard or advance the timing by 2 cam degrees (or 4 crank degrees) during engine assembly, aiding in precise timing correction or repositioning. While fitment is typically vehicle-specific, some sources mention general compatibility with AMC, Eagle, International Harvester, and Jeep models. It's recommended to confirm precise vehicle application before purchase.
