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.
