Installation Notes and Tips

Verify engine code and application details before ordering, since fitment varies by year, make, model, and engine configuration. This timing set does not include a tensioner, gaskets, or a drive sprocket, so confirm whether your repair requires those separate components. For best results, inspect related timing components for wear before installation and follow the vehicle manufacturer’s service procedure.

Quality Assurance

INA timing chain kits are engineered to include the essential parts needed for a correct timing repair. The manufacturer notes that its chain additive, used in certain applications, is formulated to reduce friction during break-in and lower run-in wear. This part is identified as premium grade and is supported by INA’s OE-focused timing component design.
