HTD Belt 20mm x 608mm

The HTD Belt 20mm x 608mm from Peterson Fluid is a precision synchronous drive belt engineered for high-performance engine accessories and supercharger applications. This belt is essential for builders and mechanics upgrading cooling systems, alternators, or forced-induction components on modified engines. The 20mm width and 608mm circumference make it ideal for compact engine bays where space and precise power transfer are critical, particularly in street performance and racing builds where belt slip cannot be tolerated.

HTD (High Torque Drive) belts feature evenly spaced teeth that mesh with matching pulleys for zero-slip operation and superior load capacity compared to serpentine belts. The Peterson Fluid 05-1911 model uses high-quality elastomer and reinforced cord construction to handle sustained engine speeds and the vibration cycles common to modified powerplants. At just 0.18 lbs, this lightweight belt minimizes parasitic drag on the crankshaft while maintaining the rigid tooth engagement necessary for reliable power delivery to superchargers, alternators, and water pumps in demanding applications.

Mechanics and engine builders rely on HTD Belt 20mm x 608mm belts when upgrading accessory drives on LS, small-block, and big-block engines, as well as modern turbocharged platforms. The 608mm length works best with compact pulley setups typically found on high-output alternators and remote supercharger mounting kits. Proper pulley alignment and tension adjustment (following manufacturer specs) ensure maximum belt life; inspect regularly for tooth wear or glazing, especially after hard acceleration or track sessions. This is the belt to choose when factory serpentine systems prove inadequate for your modified engine's power output.
