INA ZC-C398F Engine Timing Chain Steel Inverted Roller

The INA ZC-C398F is a steel inverted roller engine timing chain engineered as a precise OEM-quality replacement. INA's timing chain line is built to synchronize crankshaft and camshaft rotation, ensuring accurate valve timing for each cylinder throughout the engine's operating cycle.

This chain is pre-stressed and heat-treated for increased durability, and features precision-cut plates and rollers with a smooth finish for reduced wear and quiet operation. Precision pitch control ensures proper chain-to-sprocket tooth fitment, helping maintain consistent valve timing over the life of the component.

Key Features:

• Steel Inverted Roller Construction — provides strength and durability in high-stress timing applications
• Pre-Stressed & Heat-Treated — engineered for increased longevity and fatigue resistance
• Precision Pitch Control — ensures accurate chain-to-sprocket tooth engagement
• Precision-Cut Plates & Rollers — smooth finish reduces friction and minimizes noise
• Meets or Exceeds OEM Specifications — direct replacement for factory timing chain
• Cross-References: Cloyes C398F, F77Z6268AB, 9398F, 398F

When replacing the timing chain, it is strongly recommended to also replace the chain tensioner(s), sprocket(s), and guide(s) to ensure complete system reliability and accurate engine timing.
