Product Details
Cloyes has focused on timing systems since 1921, and the C974 reflects that experience with a chain built from premium materials, heat-treated, pre-stressed, and engineered for accurate tooth fit. The result is a timing chain intended to maintain synchronization between the crankshaft and camshaft while supporting quiet operation and long-term durability. For complete timing system integrity, Cloyes recommends replacing the chain together with the tensioners, guides, and sprockets during service. This part cross-references Anchor 9974 for the same application.

What It Helps Address
- Excessive timing chain stretch
- Rattling or noise from a worn timing chain
- Incorrect camshaft and crankshaft synchronization
- Timing-related drivability issues from chain wear
- Service replacement for Mazda timing chain maintenance
Installation Notes
Verify engine code and timing system configuration before installation. Use the timing marks to confirm alignment during assembly, and inspect the tensioners, guides, and sprockets for wear before reassembly. Because timing system wear often occurs across multiple components, replacing related parts at the same time helps restore proper chain tracking and timing accuracy.
Quality Assurance
Cloyes timing components are manufactured for precise fit and dependable operation, with technical support available from the brand. The C974 is backed by Cloyes warranty coverage.
