Dual Gear Drive - Pontiac 287-455 & 4.3L V8 1955-81, Quiet, offset cam bushings included.
Replace your timing chain with a PRW Dual Gear Drive Set. These dual idler gear drives require little or no rebuilt machining. PRW steel alloy gears add longevity. Axial needle and cage thrust bearings and or/silicon bronze bushings reduce friction. Unlike timing chains, gear drives will not stretch or wear prematurely under extreme conditions. Offset bushings allow for easy cam indexing and timing changes. PRW Extreme Pressure Assembly Lube and Threadlocker Included.
