GM Performance Parts LT1/LT4 Timing Chain Set

GM Performance Extreme Duty roller timing chain sets aren't production-replacement components, but they are a great performance upgrade. They're for 1995 and newer "Gen II" LT1 and LT4 engines. The sets include a roller timing chain plus steel cam and crank sprockets, as well as a steel water-pump gear, and are for use with pin-drive camshafts only.
