Description
The STILLEN Standard Performance Lightweight Crank Pulley is an effective bolt-on upgrade designed to reduce rotating mass and unlock hidden horsepower in your Nissan or Suzuki truck or SUV. Factory crank pulleys are typically made from heavy cast iron, which requires additional engine power just to spin. This unnecessary weight slows engine acceleration and robs performance.
By replacing the OEM crank pulley with STILLEN’s lightweight aluminum design, engine RPM increases more freely, improving throttle response and overall drivability. The reduction in rotational mass allows the engine to rev faster with less effort, translating into noticeable gains in horsepower, torque, and responsiveness.
Manufactured from aircraft-quality aluminum and built to strict industry standards, this pulley is designed for long-term reliability while delivering measurable performance improvements without sacrificing everyday usability.
