Common questions
Will this part fit my vehicle?
Trim level, engine option and drive type decide most fitment questions. Send those three details or the VIN and we will check them for you.
Do you ship the same day?
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?
Contact support before removing or returning anything, so the right process starts on the first message and nothing is voided by accident.
Is the part inspected before dispatch?
Lines and fittings are checked for pressure rating, inner diameter and ply count before shipping.
