    Brakes and hubs

    After talking to the salesman he sold me the wrong parts $300 shipping and $300 return shipping that they wouldn’t cover then try saying I used one but it wouldn’t even close to the right part

    Hi Kevin,

    We sincerely apologize for the confusion with the parts and the frustrating experience you've had with the shipping costs. It's definitely not the service we want to provide when our customers are working on important trailer projects.

    We understand how disappointing it must be to receive parts that don't fit your application, especially after speaking with our sales team. We take full responsibility for the mix-up and want to make this right.

    Thank you for taking the time to share your feedback with us, as it helps us improve our service.
