What to know before buying

Listing details to confirm

Fitment claims are limited to crew-cab trucks and exclude diesel-engine models. The listing also says it does not fit 2020-2025 Silverado models or the 2007 Silverado Classic. Confirm the exact vehicle year, model, cab and engine before ordering. The listing is inconsistent on product length, giving 89 inches in specifications and 86 inches in a separate answer, and gives different load claims of 500 pounds per bar and 450 pounds for the boards. A claimed fit for a 2024 Colorado Trail Boss in customer feedback conflicts with the stated Silverado/Sierra fitment, so that application is unconfirmed.

Customer feedback reports easy installation, improved ease of getting into and out of trucks, and positive impressions of fit and build quality. Instructions receive mixed comments, and durability feedback is also mixed, with some customers reporting rust. Those experiences matter for a fixed step product expected to see regular use, but do not establish fitment for a particular truck. The aggregate ratings skew strongly positive, while a smaller low-star share indicates that experiences are not uniform.

Positive themes

Customers report easy installation and easier entry and exit.

Frequently asked questions

Which trucks are these running boards listed to fit?

The stated fitment is for 2007-2018 Silverado/Sierra 1500 crew cabs and 2007-2019 Silverado/Sierra 2500HD and 3500HD crew cabs. The listing excludes diesel-engine models and 2007 Silverado Classic trucks. Verify the exact vehicle configuration before ordering.

Are mounting parts included?

The stated included-components list names two steps, one left and one right, mounting brackets, hardware and installation.

Do they require drilling?

The manufacturer describes them as direct bolt-on and says drilling is not needed.

What load capacity does the listing claim?

It states 500 pounds per bar in one feature claim, but elsewhere says the boards support 450 pounds. The load claim is therefore inconsistent in the listing.
