Running Boards 6 in Compatible with Crew Cab 2007-2019 - Two-Stair

In this review the Perfit Liner style running boards are judged on fit, durability and daily usefulness for crew cab Chevrolet and GMC trucks. The bottom line: these 6 in two-stair side steps are best for owners of 2007-2018 Silverado and 2007-2019 Sierra crew cab trucks who want a sturdy, no-drill bolt-on step that improves access and protects rocker panels. The review finds the biggest reason to buy is the combination of a secure, non-slip two-step design and robust carbon steel construction that resists corrosion and supports heavy loads.

Key Features

• Compatibility: Designed for crew cab 2007-2018 Chevy Silverado and 2007-2019 GMC Sierra 4-door models, providing a direct-fit option for these trucks.
• Two-stair design: Adds an extra lower step that makes entry easier for children or older passengers and provides a stable stepping position.
• Durable construction: Built from carbon steel with a high-quality black powder coat to resist rust and hold up to regular use.
• Non-slip surface: Precision laser cutting and stamping create traction on the step surface for safer footing in wet or muddy conditions.
• Hollow design: Prevents water and sediment accumulation inside the board, reducing corrosion risk over time.
• Tool-free final fit: Simple bolt-on installation with pre-aligned holes that can be completed in about 30 minutes without drilling.

Who It's For

The running boards suit owners of full-size crew cab Silverado and Sierra trucks who need a reliable step for frequent entry and exit, particularly families with children or drivers who want a lower step for easier access. Owners who want to protect rocker panels from road debris while adding a sleek black side profile will also appreciate these boards.

These steps are not intended for diesel models equipped with a DEF tank, so buyers with those trucks should look elsewhere. Drivers seeking a lightweight aluminum option or a finished chrome factory appearance may prefer alternative styles.

Pros & Cons

• Not compatible with diesel models that have a DEF tank, limiting fit for some truck owners.

Specifications
