Why do I need a bronze distributor gear with a steel roller camshaft?

A stock cast iron distributor gear is not compatible with a steel camshaft. Using the wrong gear can cause damage to your camshaft. A bronze gear is required to ensure proper compatibility and longevity of your steel roller cam.

What is the shaft diameter this gear fits?

This COMP Cams bronze distributor gear is designed to fit a shaft diameter of 0.491 inches. This is a common size for many Pontiac V8 engines.

What is the material of this distributor gear?

This distributor gear is machined from AMPCO-45 extruded aluminum bronze with 5% Nickel added. This material provides high strength and wear resistance.

Product Details

When you're installing a steel roller camshaft, you'll need to swap out your stock cast iron distributor gear for a bronze one. A cast iron gear just isn't compatible with a steel cam and can cause damage. This bronze distributor gear from COMP Cams is designed specifically for Pontiac V8 engines with displacements from 265 to 455 cubic inches, and it fits shaft diameters of 0.491 inches. It's a well-built component that ensures your new camshaft gets the protection it needs.

COMP Cams machines these gears from AMPCO-45 extruded aluminum bronze, with 5% nickel added for extra toughness. This material choice, along with a high-strength tooth design, means the gear can resist wear even when paired with high-pressure oil pumps. This is important because higher mechanical properties are often demanded in performance applications, and this gear is built to handle that.

This gear is a direct fit for a wide range of Pontiac V8 engines, as well as some Buick and Oldsmobile models from the late 70s and early 80s, like the Pontiac Firebird, Buick Regal, and Oldsmobile Delta 88. Make sure to check the fitment details to confirm it's the right part for your specific vehicle.
