Description
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.
