The unitized design is much better than the old style seals. No more oil leaks and the dual-action feature reduces wear on the spindle. Great product!

Exact Fit for Dexter 9K Axle

These seals matched my hub casting number exactly. The 2.875" inner diameter was perfect and installation went smoothly. The black color looks professional too.
