What do you need to verify fitment?
Send your VIN or your year, make and model and our fitment desk confirms the part against manufacturer data before it ships. The check is free and usually answered the same business day.
When will my order dispatch?
Orders placed before early afternoon on a business day usually leave our USA warehouse the same day, and tracking is emailed when the label is created.
What if it does not fit?
Report any transit damage with a photo and we will send a replacement or refund you. We handle the carrier claim ourselves.
Is this checked before shipping?
We verify diameter and reinforcement specification on every hose order.
