Durable and reliable gear for Ford 289/302 engines with advanced features.
The MSD Ignition Distributor Drive Gear is engineered specifically for Ford 289 and 302 cubic inch engines, featuring a shaft diameter of 0.486 inches. This gear is constructed from a proprietary formulated ductile iron, ensuring enhanced durability and performance. The gear undergoes a meticulous heat treatment and is coated with Melonite QPQ, which significantly reduces friction and initial wear, contributing to a longer lifespan.
MSD engineers have dedicated extensive resources to research and test various metallurgical compositions, resulting in a drive gear that boasts an increased outer hardened layer thickness. The micro-polished surface allows for smooth contact, improving the overall efficiency of the distributor. This gear is designed for standard rotation, making it a reliable choice for your engine’s ignition system.
With a focus on wear resistance and running properties, the interstitial carbide concentration in the gear enhances its performance under various operating conditions. The MSD Ignition Distributor Drive Gear is a critical component for maintaining optimal ignition performance in Ford 289 and 302 engines.
