Drive Kit Serp. LS CT525 w/ Water Pump

The Jones Racing Products Drive Kit Serpentine LS CT525 with Water Pump (part number 1020-LS-EMP) is a complete 6-rib serpentine pulley and accessory drive system engineered for LS-series engine blocks. This aluminum drive kit features black anodized construction and integrates the water pump into a single, coordinated assembly, eliminating the need for piecing together separate components from multiple sources.

The serpentine belt configuration reduces installation complexity while the integrated water pump ensures proper coolant circulation flow rates matched to LS engine cooling demands. The black anodized finish provides corrosion resistance and a clean engine bay appearance, critical for both street and marine installations where salt spray and humidity accelerate oxidation. The aluminum construction keeps rotating mass minimal, reducing parasitic drag on the crankshaft—a measurable advantage in applications where engine efficiency and reliable cooling matter. This drive kit is designed to fit GM LS-series engines commonly found in marine engine swaps, performance builds, and late-model powerboat applications where aftermarket engine conversions demand quality accessory drive components.

Buyers upgrading or troubleshooting LS-swap cooling systems benefit from having a matched pulley and pump assembly rather than sourcing components individually—fitment uncertainty is eliminated. The CT525 designation indicates this is a specific accessory drive package, making it straightforward to identify the correct kit for LS-block installations. Weighing 13.36 pounds, the complete assembly integrates serpentine belt routing, alternator mounting provisions, and water pump engagement in a single unit, simplifying engine bay layout and reducing potential coolant leaks from multiple connection points.
