Distributor Gear Bronze .491in Chevy

The COMP Cams Distributor Gear Bronze .491in Chevy is a precision-engineered component designed for small-block and mid-size Chevrolet and GM engine platforms. This bronze gear serves as the driven element in the distributor drive system, transmitting camshaft rotation to the distributor at the correct mechanical ratio to maintain ignition timing synchronization across engine operating ranges.

The .491-inch shaft diameter specification ensures direct compatibility with corresponding distributor drive tangs on Chevy V8 and GM V6 engines. Bronze material selection provides controlled wear characteristics and corrosion resistance superior to ferrous alternatives, critical for long-term reliability in fuel-injected and carburetor-fed systems. Weighing 0.36 lbs with compact dimensions (2.8 x 2 x 4.1 inches), this gear integrates seamlessly into factory and performance engine builds without modification to existing engine block geometry or distributor mounting provisions.

This component is essential for engine builders, restoration specialists, and powertrain technicians performing distributor replacement, timing system repair, or engine refresh on Chevy small-block and mid-size GM V6 platforms. Proper distributor gear installation directly impacts ignition timing stability, engine start reliability, and cold-start performance. OEM-specification construction ensures fitment without machine work or clearance modification.

COMP Cams distributor gears are manufactured to original factory tolerances, making this part a direct functional replacement for original equipment or a foundation component for modified ignition systems. Each gear is inspected for dimensional accuracy before shipment.
