Designed for years of service
even in the dirtiest riding environments.
OE Spacers typically wear
out within a year of hard riding. OE wheel spacers should be checked and
replaced as needed with every wheel bearing change.
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.
The AB aluminium spacers feature a hardened steel shell pressed over
the aluminium to provide superior wear surface.
The AB steel spacers
are manufactured with 52100 bearing steel that is through hardened and
precision ground and plated for years of service.
