  • So far, no complaints
Color: 3 Spindle
The Spindle Assemblies fit perfectly and have performed without issue. I cannot speak to the longevity of the units, but for now I am satisfied with the purchase. In the past I have simply replaced the bearings, but decided to do a complete spindle replacement this year. Good thing I did. In replacing the spindles I noticed a crack in one of the old spindles, so it was definitely time for a full replacement. ... show more

  • Not much grease.
Color: 3 Spindle
Arrived on in good packaging. Looks like it was milled from solid aluminum with steel bearings. The price was good. When I checked the bearings there was very little grease. It took some time but I was able to pack them with an ample amount of grease.

  • Excellent fit but not enough grease
Color: 3 Spindle
I purchased these for a Bad Boy MZ 54" mower. They are an exact replacement and fit perfectly. The only downside is the bearings come with little grease, this is the reason why they fail so quickly. The original oem ones have the same flaw. I simply pop off the cover and added more grease. It took 5 pumps worth from a Lincoln grease gun, however much that is. 😆 ... show more

Color: 3 Spindle
Was a bit worried ordering these but needed replacements fast. They fit perfectly and have been used a lot with no issues. These were very close to factory construction. Thanks
