Why change your factory shaft several times a season just to keep coolant from leaking out of your engine? Eliminate water pump seal leakage with the New water pump shaft manufactured by CV4. Specially designed for both Yamaha 450F MX and ATV's, this shaft also fits 98-up 400/426 engines. Each shaft is manufactured from 8620 steel, and is case hardened to prevent wear. A super-finishing process drastically reduces drag, while a coating of titanium nitride is then added for maximum strength and durability.
