## Before you buy

- Fit is specified for Crew Cab models with four full-size doors.

## Customer feedback

Customer feedback highlights appearance, finish, perceived build quality, and straightforward installation, including reports of simple instructions and one-person installation. Some customers describe the boards as sturdy, while flexibility feedback is mixed, with reports both of no flex and of flexing. That variation matters for buyers prioritizing a rigid-feeling step, since the listed 500-pound capacity is a manufacturer claim and does not resolve those differing experiences.

- Positive themes: Customers report easy installation and appreciate the instructions.
- Positive themes: Customers describe the boards as sturdy and well made.
