Product Details

The March Performance 10051 crank pulley is an underdrive crankshaft pulley designed to free up horsepower by reducing the rotational speed of engine-driven accessories. Measuring 5.25 inches in diameter with a 2-groove V-belt configuration, this pulley slows down alternators, water pumps, and power steering pumps to reduce parasitic drag on the engine.

Key Features:

  • Precision-machined from premium 6061-T6 billet aluminum for superior strength and durability
  • 5.25-inch diameter underdrive design for improved horsepower and throttle response
  • 2-groove V-belt pulley configuration for dual accessory drive compatibility
  • Clear powdercoat finish protects against corrosion and maintains a clean appearance
  • Lightweight construction reduces rotating mass for improved engine efficiency

March Performance pulleys are engineered to deliver measurable performance gains while maintaining reliable accessory operation. The underdrive ratio provides the perfect balance between power recovery and accessory functionality, making this pulley an excellent choice for street performance and racing applications.

Right item, right price !

First time using Autoplicity. Found some great pricing on their site. Plan on doing plenty of mods to my new truck and would definetley recommend them and would be using them again very soon.

Everything was quick and easy. It was the cheapest price I could find AND I was able to pay with PayPal. Very nice.

Best price, reasonable shipping, and they even gave me a discount AFTER I placed the order.

Fast professional service and delivery. Thank You

Autoplicity was the least expensive and had great response time in regards to shipping. I will use Autoplicity next time I am needing automotive parts. Thanks
