The Original Dual Idler Camshaft Gear Drive.

Pete Jackson Dual Idler Gear Drives connect the crankshaft and camshaft with precision machined gears to provide the ultimate in timing accuracy and reliability. They are as simple to install as a stock timing chain, fitting neatly under your stock timing cover with no machining to engine block required. Contrary to urban legend, Pete Jackson gear drives have proven, in dyno tests, to show no horsepower loss compared to traditional timing chain sets. Plus, extreme durability is an understatement with reports from Pete Jackson of their drive gears enduring over 17 seasons of oval track use and over 100,000 miles of street duty
There are two styles of gear drives available: The relatively quiet ''Traditional''-style that has been produced for years and the ''Machined for Noise''-style that is machined to produce that unmistakable mild supercharger whine.
100% made in the USA for over 30 years.
