Cog Belt Pulley - 14 Tooth 3/8in Pitch 1in Bo

The Aeromotive Cog Belt Pulley — 14 Tooth 3/8in Pitch 1in Bore — is a precision-engineered accessory drive component designed for high-performance fuel system installations and custom engine builds. This pulley is ideal for builders installing Aeromotive fuel systems, carb-to-EFI conversions, or upgrading factory fuel delivery on various engine platforms.

This cog pulley serves as the driven component in serpentine belt configurations, translating crankshaft rotation into controlled mechanical action for fuel pumps, alternators, and other auxiliary systems. The 14-tooth profile with 3/8-inch pitch is engineered to mesh precisely with matching serpentine belts, providing positive engagement that minimizes slippage.

With a 1-inch bore accommodating standard shaft diameters found across Gen-III/IV small-block Chevrolets and LS platforms, this pulley maintains concentricity and dimensional stability even under high-RPM operation. Its compact design integrates cleanly into tight engine bay layouts without requiring extensive custom fabrication.
