Description

The PRW 5145422 is a quiet dual idler gear drive set designed for 1966-1990 Big Block Chevy 396-454ci engines. Crafted from alloy steel, these gear drives provide high-precision timing and reduce drive friction.

They offer enhanced stability over single gear drives and eliminate premature wear common with timing chains under extreme conditions. The set includes offset bushings, a thrust bearing, a locking plate, and mounting hardware for comprehensive installation.
