KA24DE Crank Pulley Kit

The NonStopTuning Nissan 240SX KA24DE Pulley Kit is engineered to enhance engine performance by reducing rotational mass and underdriving accessories. These pulleys are precision CNC machined from 6061-T6 aircraft-quality aluminum, a material chosen for its strength and light weight. Each part is rigorously tested for machining and balance tolerances, then hard anodized to provide exceptional durability and a premium finish. The kit is available in a variety of colors to match your build. Significant weight savings are achieved with this kit, offering approximately 70% to 75% less weight compared to stock pulleys. This reduction in mass directly contributes to increased horsepower and torque, with documented average gains of 7-10 HP and ft-lbs. Beyond peak performance numbers, users can expect improved throttle response, smoother engine operation, and better fuel economy, leading to higher MPG. Compared to competitors, NonStopTuning emphasizes superior construction and features. Their pulleys are stronger and will not corrode like OEM cast iron parts. The anodizing process further enhances the aluminum's strength, making them more robust than bare aluminum pulleys. Specific design considerations include oil sleeves on crank pulleys where necessary and proper timing marks, features not always found on other brands' products. The kit targets the KA24DE engine found in the 1991-1998 Nissan 240SX, specifically for the alternator and water pump components. Further details on dyno results across various platforms and comparisons to other brands can be found on the manufacturer's website.
