Key Features

• Includes the necessary chains, tensioners, and guides
• Some applications also include gears and sprockets
• High-performance chain additive is included in certain kits to reduce break-in friction and initial wear
• Direct replacement part number: ZC-78535T-9R

Detailed Description

INA timing chain kits are assembled to cover the core components required for timing system repair in one package. This kit is used on a wide range of GM vehicles, including 2007-2013 Chevrolet Corvette, 2010-2015 Chevrolet Camaro, 2011-2015 Cadillac CTS, and 2007-2009 Chevrolet Silverado 1500 applications. The part number ZC-78535T-9R also cross-references 5591358100 for the same application.

In applications where included, the chain additive is formulated for the initial run-in period and helps reduce friction and wear during early operation. That makes this timing set a practical choice when servicing a worn or noisy timing system on compatible Chevrolet and Cadillac engines.

Common Repair Uses

• Timing chain noise or chain stretch
• Worn tensioners or guides
• Engine timing drift or cam/crank correlation faults
• High-mileage timing system service
• Valve train repair after chain-related wear

Installation Notes and Tips

Verify engine code, build date, and oil-cooling configuration before ordering, since some listed vehicles have application-specific notes. For example, 2015 Chevrolet SS and 2014 Chevrolet Caprice are listed only without the oil cooling system. Follow factory timing procedures, inspect related sprockets and seals during service, and confirm all timing marks before engine start-up.

Quality Assurance

INA timing chain kits are engineered to include the essential components needed for a complete timing repair. The included chain additive in certain applications is supplied by Liqui Moly for Schaeffler and is used to reduce break-in friction and run-in wear.
