HTD Belt 28.031in Long 20mm Wide

The HTD Belt 28.031in Long 20mm Wide (Model 712-20 HD) from Jones Racing Products is engineered for high-performance engine accessory drive systems where precision timing and reliability are non-negotiable. HTD (Hybrid Tooth Design) belts are the industry standard for custom engine builds, supercharger installations, and auxiliary component drives in modified vehicles. This 8mm pitch belt delivers positive engagement without slip, making it essential for builders who demand accuracy in crankshaft-to-accessory synchronization.

HTD belt technology uses reinforced hybrid tooth geometry to reduce wear and vibration while maintaining superior load capacity compared to serpentine or V-belt alternatives. The 20mm width and 28.031-inch length are precisely calculated for specific engine platform applications, ensuring proper tension and wrap around multiple pulleys without compromise. Jones Racing Products manufactures these belts with high-quality elastomer and cord reinforcement, providing consistent performance across wide operating temperature ranges typical of turbocharged and naturally aspirated racing engines.

Custom engine builders, hot rod enthusiasts, and professional tuners rely on Jones Racing HTD belts for alternator, water pump, power steering, and supercharger drive applications. The exact dimensions of this 28.031-inch belt make it compatible with specific engine packages—verify your pulley configuration and center-to-center distances before ordering. Lightweight at 0.19 lbs, this belt minimizes parasitic drag while maintaining the timing precision required for boost-dependent and high-RPM builds.
