Hearing a rattling noise from your engine, or having trouble starting? Could be a worn timing chain. This complete timing chain kit is a direct replacement for a bunch of GM vehicles with the 2.4L or 2.2L engine. It fits models like the Chevy Equinox, Malibu, Impala; Buick LaCrosse, Regal; GMC Terrain; and others from roughly 2009 to 2017 (check the full list carefully). The kit includes the timing chain, VVT (Variable Valve Timing) sprocket/cam phaser, guides, tensioner, and all necessary hardware—basically everything you need for the job. The parts are made from quality materials for reliable performance and smooth operation. Replacing the timing chain is a bigger job, but doing it yourself can save a ton on labor costs. Just make absolutely sure it matches your vehicle's exact year, make, model, and engine using the Amazon fitment filter. Reference part numbers include 12588387, 9-4201S, and others. Kit comes with a 30-day satisfaction guarantee from the seller, GDO.
