MORE ACCURACY
The only bearings with wall thickness variation of ±.0001” as a standard in comparison to ±0.00025”.

MORE CONSISTENCY
from bearing to bearing, requiring less adjustment during assembly

ONE SET FITMENT
The only bearings that don’t require you to buy multiple sets to achieve desired oil clearance
