All Balls Rear Wheel Spacer for Kawasaki KX250 / KX450 - 11-1042-1 2008 Yamaha YFM700R Raptor SE 2008 Yamaha YXR450F Rhino 450All Balls Racing Wheel Spacer Kit Part Number: 11 1042 1 Position: Rear OE spacers typically wear out within a year of hard riding. OE wheel spacers should be checked and replaced as needed with every bearings service. Water and dirt act as a grinding compound between the seal face and the mating surface of the spacer. Once the grooves are deep enough, the sealing surface is lost, allowing water and dirt to pass through and contaminate the bearing.
