MSD Distributor Drive Gear P/N:85834
Keep the distributor turning true with the MSD Distributor Drive Gear 85833, a steel drive gear designed for use with a roller cam and machined with a 0.468 in. ID.

The drive gear meshes with the camshaft gear to turn the distributor shaft; a worn or chipped gear can cause ignition timing scatter, distributor noise, or metal debris in the oil. MSD develops its gears through extensive metallurgy, heat-treating and coating testing, using a special alloy treated with a low-friction coating for an easy break-in period and reliable performance.
