SBC Tru Trac Pulley Sys.

The Billet Specialties SBC Tru Trac Pulley System is designed for small-block Chevrolet engine builders and performance enthusiasts looking for a polished and reliable accessory drive upgrade. This complete pulley system replaces the factory cast-iron setup with precision-machined billet aluminum components, enhancing both performance and aesthetics in the engine bay.

Constructed from high-grade billet aluminum, the Tru Trac system features precision-ground serpentine grooves that ensure proper belt tracking and reduce slip under load. The polished finish not only enhances visual appeal but also provides superior corrosion resistance compared to painted steel alternatives. The design incorporates balanced geometry to minimize harmonic vibration, which is crucial for high engine speeds or aggressive cam profiles.

This pulley system is ideal for a variety of SBC-powered vehicles, including classic hot rods, muscle cars, and modern street machines, and is compatible with both naturally aspirated and supercharged applications. Installation involves removing the factory damper assembly and replacing it with the billet pulley kit, making it a straightforward upgrade for experienced mechanics.
