GEAR DRIVE, PQx, DUAL IDLER, CHEV 396-454 1966-90, Noisy, Made in USA
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.
