Nice kit but packaged poorly. Nuts are loose in box so if the box breaks open they can just fall out. Should be bagged to help keep together. I am missing 3 of the nuts after delivery so I have to now go by more to complete the job.

4.0 out of 5 stars Fits fine. Not galvanized.
Reviewed in the United States on March 21, 2023

These were a bit tight to get around the axle, and had to be driven with a rubber mallet. But they went on and are the right diameter to be tight around the axle tube. I used anti-seize on them and torqued the nuts in increments to 70 ft lbs, the minimum recommended torque for shoulder nuts. None stripped.

The nuts and plates are not as pictured. The nuts are shoulder nuts and the plates have ridges in the center. These are inconsequential changes from the picture, other than the torque required on the shoulder vs. plain nuts.

It's all raw steel. None of it is galvanized.
