If your QR suffers from chain rattle at start up when cold, the issue more than likely is a bad intake sprocket phaser. This can lead to jumped timing, bent valves, broken chains and/or broken main crank sprockets. 2JR offers new cam phaser sprockets. We have these in stock! Do not wait to replace your sprocket and risk an engine failure. Learn More
