Unlike others, we match the hardest ceramic balls
with the hardest available races. This means no soft stainless steel races. Our races are hardened
chromium steel, cryogenically treated and polished to make them the best possible match for the ceramic balls.
The ZERŲ bearings include a Magnetite rust-proof finish and USA-made Grade 3 ceramic balls.
INCLUDES:
New drive side Silicone Seal
New drive side Wave Washer
New non-drive side Stainless Bearing Cap/Seal
New Axle Sleeve
