We have survived the Year End Holidays and hope you have as well. We are now back to our normal hours, M-F, 7-5 Central time.
We will do our best to ship your order the same day we receive it. When you order On-line, an email with the tracking number and the status "Label Created", will be sent to you. When you get this email, the label has been put on your parts and your order has been loaded onto the truck for shipment from our warehouse .

If you don't see the U-Bolt Kit you need, call your Customer Service Rep for pricing and availability, we can probably bend it for you.
