HTD Belt 24.567in Long 30mm Wide

The HTD Belt 24.567in Long 30mm Wide from Jones Racing Products is a precision synchronous drive belt engineered for high-performance engine accessory systems and custom automotive applications. Built to exacting tolerances, this HTD belt is essential for builders and mechanics running modified serpentine systems, supercharger drives, or competition engine configurations where stock belt sizing falls short. Whether you're upgrading a street performance engine or assembling a race-ready drivetrain, this belt delivers the consistency and reliability demand by serious automotive enthusiasts.

The HTD (High Torque Drive) profile features an 8mm pitch and 30mm width, providing robust load capacity and positive engagement across custom pulley arrangements. The 24.567-inch length fits compact accessory drive layouts common in engine bay modifications, eliminating the need for improvised belt tensioning or pulley spacing compromises. HTD belts maintain synchronous contact under high rotational speeds and variable loads—critical for applications where slippage could cause alternator discharge, water pump cavitation, or supercharger boost inconsistency. The polyurethane-reinforced construction resists heat degradation and ozone exposure, ensuring longevity even in underhood temperatures exceeding 200°F.

Custom builders, race mechanics, and performance shops standardize on Jones Racing Products belts for their dimensional accuracy and repeatability across test-and-tune cycles. This belt is ideal for custom serpentine installations on small-block and big-block platforms, LS engine conversions, and any application where OEM belt routing no longer applies. Verify pulley alignment and tension specifications before installation; proper belt tracking ensures maximum lifespan and eliminates premature wear on driving and driven pulleys. For competition engines, inspect regularly for glazing or fraying—early detection prevents catastrophic accessory failure mid-run.
