Replace your stock timing chain with a Precision Gear Drive. Known for years to simulate that "blower" sound. The gears are machined from premium billet steel on our state-of-the-art CNC equipment then induction hardened and oil-quenched using our in-house multi-stage heat treat process. Our Idler Gear assembly, with its honed idler gear bores, precision ground pins, and heavy duty idler brackets, ensures precise timing through the entire RPM range. Cloyes Gear Drives offer a three keyway crank gear allowing you to adjust your valve timing +/- 4 degrees.
