PRW Industries Quiet Gear Drive - Dual Gear - Dual Idler - Small Block Chevy Handheld Radio Microphones Each precision CNC-machined billet aluminumReplace your stock timing chain with a CNC machined dual gear drive, available in noisy or quiet for most applications. Dual gear drives feature two sets of gears instead of a single chain or belt. This design provides increased durability and reliability, especially in high stress or high rpm applications. The dual gears distribute the load more evenly, reducing the risk of failure or stretching. Most applications require little or no machining.
