Description

Keep the distributor turning in step with the camshaft with the Dorman - HELP Distributor Drive Gear, part number 90457, which Dorman lists as a distributor gear kit. It fits many vehicles, among them the 1975-1981 Ford F-150, 1975-1989 Ford F-250 and 1967-1973 Ford Mustang. See the "Vehicles it fits" section for the full list. Dorman designed this gear to match the original part's fit, function and appearance on the listed applications.

The distributor drive gear meshes with the camshaft gear to rotate the distributor shaft, and the ignition system relies on that rotation for spark timing. Worn or damaged gear teeth can disturb that drive.

Direct replacement: built to drop in like the factory gear for the listed applications.
Problem solver: intended to replace an original gear that failed from moisture intrusion or vibration.
Durable construction: assembled from quality components, and Dorman engineered it for durability and dependable performance.
Backed by experience: supported by a U.S.-based team of product experts and more than a century of automotive experience.

If a worn distributor gear is behind erratic timing or a no-start, this gear replaces it. Diagnose the cause first, and follow the vehicle service information for installation.
