Detailed Product Description

Gates CHK148 is an engine timing chain kit for timing drive service where precise synchronization between the crankshaft and camshaft is critical. The steel roller chain, steel sprocket, and included guides and tensioner are selected to restore timing system function in applications that call for a complete timing chain component replacement. This part cross-references Cloyes 9-4313S and Dayco KTC1407 for the same application.

Compatible vehicle coverage includes 2009-2019 Toyota Highlander, 2009-2018 Toyota RAV4, 2010-2017 Toyota Camry, 2009-2016 Toyota Venza, 2013-2018 Toyota Avalon, 2013-2018 Lexus ES300h, 2015-2019 Lexus NX300h, 2011-2016 Scion tC, and 2011-2013 Toyota Sienna. Gates CHK148 is also listed for interference engine applications, making correct timing system condition especially important during service.

Common Problems This Kit Can Address

• Timing chain stretch or chain noise
• Worn guides causing rattling or uneven chain tracking
• Weak or failing tensioner performance
• Timing drift that can trigger drivability concerns or fault codes
• Service needs on interference-engine timing systems

Installation Notes and Tips

Verify engine code and VIN-specific fitment before ordering, since timing components can vary by application. Inspect sprockets, guides, and the tensioner mounting surfaces during service, and replace any worn mating parts as needed. Follow factory timing marks and service procedures carefully to maintain correct camshaft and crankshaft synchronization.

Quality Assurance

Gates builds timing drive components for original equipment and aftermarket use, and this kit is engineered to meet or exceed OE standards in function, fit, and performance. For buyers searching for a Toyota Highlander timing chain kit, Toyota RAV4 timing chain kit, or Lexus ES300h timing chain kit, the Gates CHK148 offers a complete timing service solution backed by Gates’ timing drive system experience.
