FAQs
Find answers to common questions we receive about our high-performance and True® Roller timing sets.
Contact UsWhat’s included in a Cloyes timing chain kit?
Kit contents vary by part number and application. Base Kits generally include timing chains, tensioners, and guides and may include sprockets and application-specific hardware. Expanded configurations may add VVT phasers and solenoids, a water pump, or front engine accessory drive components. Review the individual product listing to confirm exactly what is included.
What is the difference between a timing chain kit and a timing belt kit?
Both systems synchronize the crankshaft and camshaft, but they use different components. A timing chain system uses metal chains and sprockets, while a timing belt system uses a reinforced toothed belt. Timing belts commonly have application-specific inspection or replacement intervals. Timing chain service is generally based on system condition, diagnosis, and vehicle manufacturer guidance.
Should I use a timing kit or replace an individual component?
That depends on the application, the condition of the timing system, and the scope of the repair. A kit brings together multiple components for a broader timing system service, while individual components support more targeted repairs. Inspect the complete system and follow the service information for the specific vehicle and engine.
