Running boards and towing gear carry real loads, so bracket engineering matters more than tube finish. Confirm cab configuration twice, because that is where most returns originate.
Buyers comparing the step-down black will find the specification detail on this page rather than in a catalog footnote.
The step-down black listed here is checked against your vehicle before dispatch.
Every step-down black order goes through the same fitment review.

Before you order
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.
How quickly can I get this?
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?
Report any transit damage with a photo and we will send a replacement or refund you. We handle the carrier claim ourselves.
What happens before my order ships?
Boards and towing gear are verified against your cab and bed configuration before dispatch.
