The True Trac Pulley System from Billet Specialties is designed for serious engine builders and high-performance enthusiasts who require precision in accessory drive management. This premium pulley assembly optimizes belt tension, reduces parasitic drag, and enhances overall engine efficiency, making it essential for maximizing horsepower in various applications.
Constructed from precision-machined billet aluminum, the True Trac system ensures durability and minimal runout, outperforming standard cast pulleys. Its engineering reduces accessory load on the crankshaft by optimizing serpentine belt geometry and idler pulley positioning, which can lead to measurable power gains at the wheels, typically between 8 to 15 hp depending on engine configuration.
Ideal for small-block Chevrolet, big-block, LS, and Gen III/IV platforms, the True Trac Pulley System is favored by professional mechanics and engine builders. Its polished or powder-coated finish resists corrosion while maintaining an appealing appearance, making it a reliable choice for both performance and aesthetics.
