Unleash the full thrust of your classic ski with high-performance Kawasaki 440 & 550 pump and impeller upgrades. The pump is the heart of your ski’s propulsion, and optimizing this system means faster holeshots, better top-end speed, and tighter acceleration response. Whether you’re replacing a worn stock impeller or stepping up to a custom-pitched stainless version, our collection delivers smoother water flow and more efficient power transfer. Pair it with upgraded wear rings, pump cones, and nozzles to reduce cavitation and fine-tune your ski’s handling and trim. Our 440 & 550 jet pump components are trusted by racers, freeriders, and restoration experts looking for maximum performance and reliability from their vintage Jet Skis. At IPDRacing.com, we only stock pump parts we’ve tested and trust—so you can ride harder, plane quicker, and keep your ski performing at its peak.
