HTD Belt 30.866in Long 20mm Wide

The HTD Belt 30.866in Long 20mm Wide by Jones Racing Products is a high-performance synchronous drive belt engineered for automotive engine modifications, supercharger installations, and custom accessory drive systems. Built to tight tolerances and precision specifications, this belt is essential for builders and mechanics upgrading factory engine configurations or swapping alternative powertrain components. Whether you're installing a centrifugal supercharger, upgrading to a larger alternator, or reengineering your cooling and accessory systems, the correct belt length and width are critical to reliability and component longevity.

This HTD synchronous belt features an 8mm pitch tooth profile, which provides positive engagement without slippage—a must-have characteristic in high-load applications where traditional V-belts would creep or slip under peak acceleration. The 20mm width delivers substantial load capacity while maintaining compatibility with modern serpentine and custom drive arrangements. At 30.866 inches in circumference, this belt accommodates tighter pulley spacing than factory configurations, enabling compact packaging of auxiliary components. Jones Racing Products manufactures to OEM-grade dimensional accuracy, ensuring the belt seats properly in HTD-profile pulleys without binding or excessive tension variance.

Professional engine builders, performance shops, and street-driven enthusiasts rely on HTD belts for forced-induction setups, fuel injection pump drives, and high-RPM accessory systems where synchronous power transfer is non-negotiable. Verify pulley diameters and center-to-center spacing on your custom application before ordering to confirm this 30.866-inch length is correct for your installation. Always pair this belt with matching HTD-profile pulleys and maintain proper tension per manufacturer guidelines—typically 50–100 pounds of deflection force—to maximize belt life and prevent premature wear or component damage.
