Drive Kit HTD SBC Crate P/S W/P & Alt w/Fan

The Jones Racing Products Drive Kit HTD SBC Crate P/S W/P & Alt w/Fan is a complete serpentine belt drive system engineered for small block Chevy marine and automotive engines. This HTD (High Torque Drive) pulley kit delivers precision synchronous power delivery to critical engine accessories—power steering pump, water pump, and alternator with integrated cooling fan—in a single integrated assembly. The black anodized aluminum construction resists corrosion in salt air and harsh marine environments while maintaining the lightweight profile essential for crate engine installations.

HTD belt systems offer superior grip and load-carrying capacity compared to serpentine V-belt alternatives, translating to more reliable accessory function under demanding marine duty. The complete kit—including all pulleys, tensioner, and fan assembly—eliminates the need for sourcing individual components and ensures proper alignment and belt routing from initial installation. At 28.5 pounds, the assembly is engineered for minimal weight penalty while delivering the durability required for extended offshore operations. The modular design integrates seamlessly with small block Chevy crate engine packages, whether used in retrofit marine installations or new builds.

This drive kit addresses the specific challenges of crate engine installations where OEM serpentine systems may be undersized or incompatible. Boaters and engine builders transitioning to new block assemblies, upgrading cooling capacity, or demanding higher electrical output for marine electronics benefit from a purpose-engineered kit that eliminates custom fabrication. The integrated fan assembly ensures adequate coolant circulation—critical in closed freshwater and saltwater cooling loops where thermal management directly impacts engine longevity. Jones Racing Products' HTD technology has proven track record in both road and marine performance applications.
