Perfect bolt on replacement

Perfect fit for my 2013 Ranger Z520c dual axle trailer

Great replacement

About 45 minutes to get the old unit off and less that 15 minutes to install the new one! Works perfect and worth every penny. Buying the individual parts for the repair would have been very close to the cost of this unit not to mention the added time to assemble it and the Vault system is considered the best on the market.

Trailer locks up in reverse

Used the entire assembly. Was a pain to install but after 3 hours got old one off . 30-45 minutes to install new. Customer service was fantastic thanks Luis! Hint mark spleen notches before you get started!

Great replacement

This item works great. It was a little more money but way easier then sourcing all the correct bearings and having to pack them correctly.

Vault DB35

Ordered online and arrived within 6 days(California to Central Florida). Box had two holes but the hub assembly was undamaged. Bolted right up and wheel was on within 20 minutes. Best price I could find online!

worth every hundreds of dollars

yes, they were expensive.

yes, expensive, compared to other competitors. But they were a dream to work with. Texas Gulf Coast is a nightmare on boat trailers. Wheels would not even turn due to the corrosion, Somehow I managed to cut the whole rusted mess off the splined spindles. Exhausting work to say the least. I opted on this supplier as I knew cheaper products would just give me additional headaches I did not need. These assemblies slid right on and spinning one nut on each and I was ready to go fishing. In this instance I feel that the customer got MORE than he paid for.
