PRW Industries Quiet Gear Drive - Dual Gear - Dual Idler - Small Block Chevy JB4SM Babbitt is designed to deformReplace 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.
