    Axle upgrade

    Some negatives some positives. Overall positive. Needed to upgrade my dual 3500 lb axles to dual 6k axles. Website offered custom spring spacing option that I needed to make these axles fit on the trailer. There is a box to check to acknowledge there will be no warranty or returns if the entered spring center measurement is greater than their limits but they can still make them. I checked that box and paid. They then reached out to me several days later to double check that I measured correctly and knew there would be no warranty or returns, I confirmed. Then the guy in the shop called me a few days after that making sure that my measurements were right and I knew there would be no warranty or returns before he welded the spring carrier into position. The delay in reaching out and fact they ensured it three times cost approximately a week. But on the other hand it does prevent screwups. I can imagine they don’t get a-lot of those custom orders with that box checked and sometimes when they do people aren’t reading the fine print or don’t know how to use a tape measure. Either way, they were eventually shipped and arrived. At some point in shipping the box holding the smaller hardware broke open. The delivery guy handed me a handful of loose bolts and nuts, some ended up being missing. Whether that is the sellers fault or the shipping company… maybe a bit of both. You decide. I was able to install using some of the hardware I had just removed. It was all identical and still…

    Thank you for the detailed feedback, Larry. I apologize for the shipping issue that caused some of the hardware to be lost in transit. I'm glad you were able to complete the installation with your existing hardware and that the custom axles were made exactly to your specifications. We appreciate your patience with our verification process - while it does add time, it helps ensure we get custom orders right the first time. Thank you for the helpful installation tips for other customers and for your business!
