The 6 Rib 5-3/4in Crank Pulley from March Performance is a crucial upgrade for engine enthusiasts looking to enhance accessory drive efficiency and minimize parasitic drag on naturally aspirated or forced-induction engines. This serpentine pulley is designed to replace the factory unit and effectively drives alternators, water pumps, and power steering components.
With a diameter of 5.75 inches, this pulley optimizes pulley ratios for street and mild performance applications. Its aluminum construction keeps rotational mass low, which helps reduce the inertial load on the crankshaft, thereby improving throttle response and acceleration. The six-groove design ensures reliable belt engagement, preventing slippage during high-RPM operation or boost conditions.
This versatile crank pulley is ideal for engine swaps, restorations, and performance modifications where OEM pulleys may fall short. Mechanics and enthusiasts appreciate March Performance pulleys for their durability and precision engineering, making them a favored choice in both street performance and naturally aspirated applications.
