Noisy Dual Idler Gear Drives

Our noisy gear drives are great for you folks who want better timing and a choice of "noisy" operation. Their dual-idler design has CNC-machined components and they are easy to install. Each set comes with a pressed-in Torrington bearing or an SAE 660 bronze thrust washer (varies by application), as well as a cam gear that allows for timing adjustments in two-degree increments. These drives fit under your stock timing cover and come complete with instructions. Minor machining is required on models with the bronze thrust washer. Not designed to work on engines with a knock sensor. Not designed for use with factory equipped hydraulic roller cam and lifter engines. Check out our other listings for more vintage style items!
