Used Timing Gear 1990–2019

A timing gear is a sprocket or gear on the camshaft or crankshaft that drives the timing system. In a timing gear drive setup, these hardened gears mesh directly rather than using a belt or chain. They're common in heavy-duty engines, diesel trucks, and performance builds because of their durability and accurate timing retention over high mileage. Worn timing gears make a distinct rattling or whirring noise from the front of the engine, especially at idle. Excessive backlash between the cam and crank gear causes ignition timing to wander, leading to rough running, low power, and worse fuel efficiency. Gear wear accelerates once the oil film breaks down. Our marketplace has 14 used timing gears from 5 sellers across 9 makes. These are popular in engine rebuilds where worn or chipped gear teeth need replacing without sourcing an entirely new short block. Filter by engine type and year on Redline to find a compatible used timing gear from Chevrolet, Honda, Bmw, Infiniti, Mercedes Benz and other popular platforms. Match by tooth count and pitch diameter to your existing gear set, and confirm tooth profile with the seller.
