A distributor is only as accurate as the gear driving it, and a worn or mismatched gear will chew up a camshaft as well as scatter timing. This is the replacement cast iron gear for Ford 289 and 302 distributors with a 0.468 in. shaft, using the same ductile iron and surface treatment specification as the gears installed on new distributors.

MSD 85832 Cast Iron Distributor Drive Gear Features:

• Fits Ford 289 and 302 distributors with a 0.468 in. shaft.
• Proprietary formulated ductile iron construction.
• Melonite QPQ coating reduces friction and initial wear.
• Increased outer hardened layer thickness at RC 55-60.
• Interstitial carbide concentration improves wear resistance.
• Micro polished surface for smooth contact.
