Buyer questions
Can you check fitment before I order?
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.
What are the shipping times?
Same business day dispatch applies to orders placed before the early afternoon cutoff, with tracking that updates at every carrier scan.
Is there a warranty on this?
Contact support before removing or returning anything, so the right process starts on the first message and nothing is voided by accident.
What happens before my order ships?
Boards and towing gear are verified against your cab and bed configuration before dispatch.
