Lightweight Racing Pulley

The 2J-Racing lightweight racing pulley is a direct replacement component designed to enhance your vehicle's performance by reducing rotational mass. Constructed from solid billet 6061 aluminum, this pulley is 80% lighter than the OEM unit, weighing in at just 1 lb compared to the stock 5.1 lbs. This significant weight reduction translates directly into less rotational inertia, allowing the engine to rev more freely and quickly. Installation is straightforward, often taking less than 30 minutes, as the pulley features the factory timing marks and does not necessitate a belt change. It is designed as a simple bolt-on modification to provide an immediate increase in power. The pulley is available in anodized finishes of red, blue, or black. This pulley is compatible with various Nissan models equipped with the 2.5L QR25DE engine, including the B15 Sentra (2002-2006), B16 Sentra (+07), Altima (all years), Frontier (all years), and Rogue (all years). An optional power steering pulley, designed for 2002-2006 QR25DE (Gen1) models, is also available in matching colors, along with a required long drive belt. The manufacturer claims a performance gain of 5 wheel horsepower (whp) and 5 wheel torque (wtq) from this upgrade.
