The R&D RXT-X Pump Cone Kit is an inexpensive and creative bolt on part that adds extended length over the O.E.M. plastic pump cones length, which will reduce cavitation while adding additional pump thrust. Spacing the pump cones length will add to top speed while keeping the engine rpms stable and out of the rev limiter! Precision cast aluminum, CNC machined, and o-ring sealed for leak free pump bearing protection. Available at R&D.
