Received great customer service as I had to contact them to ...
Bought to replace the 2500 lb axles on my boat trailer. The overall fit was an exact match to my old hangers. So I didn't need to use the hangers in this kit. Received great customer service as I had to contact them to get one of the hub caps replaced. They also delivered on time.
