Splitstream Hi-Flow Water Pump Kit Yamaha YZ 450 2014-2020 (Oversized)

CLOSEOUT!

Billet construciton with Hi-Flow Impeller! 

 The 2014/2020 Yamaha YZF 450 introduced a new lightweight plastic waterpump impeller design that is proving to be problematic because of the waterpump shaft snapping in half!

Riders are reporting failure at an alarming rate at around the 5 hour point and there has been at least one failure on a stock bike as early as 1.5 hours of race use . This is especially concerning as you won't know that it has failed until it is too late and serious engine damage may have occurred from overheating . We developed this waterpump shaft kit out of a heat treated billet steel with a bronze surface treatment to prevent corrosion and improve resistance to wear .
This waterpump shaft kit solves the problem for good and is available as a standard and oversized version .
