Perfect Fit for 25K Axle

The seal slid right into place. No hammering, no struggles. Just a clean, tight fit. The ribbed design is a nice touch for keeping contaminants out. My fleet is now running perfectly.

Great Replacement, Easy to Install

Replacing the seals on my commercial trailer fleet is a regular maintenance task. This product makes it easy. The unitized construction means less fumbling and a more secure fit every time. Definitely a keeper.

Easy Install, No Tools Needed

This seal just slid right in by hand with a light tap at the end. The unitized design makes it so much easier than other seals I've used. I highly recommend it.

Minor Shipping Dent, But Still Works

Got a small dent on the outer rim of one seal during transit. It was minor enough not to affect the fit or function, so I didn't bother with a return. The seal itself is solid and works perfectly.
