COMP Cams Distributor Drive Gear

COMP Cams Distributor Drive Gears: Precision-Engineered for Street and Race

When you upgrade to a performance camshaft, the distributor drive gear becomes one of the most critical — and often overlooked — links in your valvetrain system. A worn or mismatched gear introduces spark scatter, inconsistent ignition timing, and accelerated wear on both the cam and distributor shaft. COMP Cams has addressed this problem head-on with a dedicated lineup of distributor drive gears engineered to match their own high-performance camshafts and survive the demands of serious street and race use.

Two Proven Technologies: Melonized Steel and Composite

COMP Cams offers distributor drive gears in two distinct material families, each targeting a specific set of engine builds and performance goals.

• Melonized Distributor Gears: These gears undergo a salt bath nitriding process that creates an extremely hard surface — harder than iron — making them compatible with hydraulic and solid roller iron gear camshafts while preventing excessive friction and wear. COMP Cams' melonized distributor gears are designed to provide universal compatibility for any steel, cast iron, or ductile iron camshaft, without the wear concerns of bronze options. Popular part numbers like the 410M (.500" shaft, Chevy SB/BB), 412M (.491" shaft, Chevy SB/BB), 431M (.468" shaft, Ford SBF), and 435M (.531" shaft, Ford 302/351W) cover a broad range of domestic V8 applications.
• Composite Distributor Gears: COMP Cams composite distributor gears are manufactured from carbon ultra-poly composite to ensure superior strength and less wear — the latest in high-tech distributor gear design, developed to solve the wear issues associated with bronze gears in racing applications. These polymer gears are ideal for street roller applications, featuring virtually no wear and eliminating the problem of spark scatter associated with worn bronze gears. Fitments include GM applications with oversized (.006" and .009") and beveled options, as well as Ford FW engines in both .467" and .530" shaft diameters.

Why Choose COMP Cams for Distributor Drive Gears?

Recognized as the absolute leader in valvetrain technology, COMP Cams produces components that are the product of extensive engineering work, hours of R&D, and state-of-the-art manufacturing processes. That same commitment extends to their distributor gear lineup. The COMP Cams philosophy has never changed: make the highest performing products possible and lead the industry in technological development — because performance is defined by what happens out on the race track.

For the ultimate in race-winning reliability, COMP Cams' competition-grade components incorporate the same race-winning technology used in NASCAR and NHRA competition. This is especially important with distributor drive gears, where gear wear directly impacts ignition timing accuracy and, ultimately, consistent power output. Whether you are building a mild street roller or an all-out race engine, matching your cam upgrade with a COMP Cams distributor drive gear ensures the entire valvetrain system works in harmony.
