As the title states. Here is what the manufacturer says about the product:

The R&D RXP Anti-Cavitation Pump Cone Kit will reduce overall internal pump cavitation within the Sea-Doo’s offset reduction/compression nozzle design. The O.E.M. reduction/compression nozzle is offset, while the O.E.M. pump cone/bearing cap remains straight which causes uneven pressures within the pump and reduction nozzle. The R&D Anti-Cavitation Pump Cone is offset and reshaped to match the O.E.M. reduction nozzle offset promoting even pressures, which will substantially reduce cavitation, increase pump hook up, boost acceleration, and increase top speed performance.

I will also include the spacer.

Cone retails for $103.81
Spacer retails for $21.62

$100 shipped for both.
