Pulley Serpentine 6.0in P/S Press Fit

The Pulley Serpentine 6.0in P/S Press Fit from Jones Racing Products is a precision-engineered power steering pump pulley designed for high-performance and modified automotive applications. This component is essential for builders and mechanics seeking to optimize serpentine belt drive systems on custom engines, particularly in street machines, drag cars, and restorations where OEM pulleys fall short. The 6-inch diameter sizing accommodates specific engine bay layouts and serpentine belt configurations, making it a direct upgrade path for those running aftermarket power steering systems or modified water pump and alternator combinations.

Built from aluminum and finished in black anodize, this press-fit pulley reduces weight compared to cast iron factory units while maintaining durability under sustained high-RPM operation. The 6-rib serpentine profile ensures compatibility with modern multi-groove belting systems, delivering consistent power transmission with minimal slippage across the power steering pump shaft. Press-fit construction eliminates the need for additional fasteners on the pump shaft, creating a clean, streamlined installation that reduces parasitic drag and simplifies belt tensioning. The black anodized finish provides corrosion resistance in underhood environments while delivering a finished appearance that complements modern engine bay aesthetics.

Mechanics and engine builders rely on this pulley when constructing custom serpentine systems for engine swaps, crate motor installations, and street performance builds where stock pulley spacing or diameter won't work. Compatibility with Jones Racing Products serpentine systems makes this a preferred choice for coordinated belt drive packages. Installation requires pressing the pulley onto the power steering pump shaft—a straightforward procedure for shops with proper press tooling or access to pulley installation services. At 0.84 lbs, the lightweight aluminum construction contributes to reduced overall engine parasitic load, translating to measurable improvements in power output and efficiency on dynamometer testing.
