Running Boards vs. Side Steps vs. Rock Rails: Choosing the Right Accessory
Updated October 9, 2026 · Horne Chrysler Dodge Jeep Ram parts, Globe, AZ
When considering accessories for your truck or SUV, running boards, side steps, and rock rails all offer different benefits, primarily revolving around ease of entry and protection. Running boards and side steps are designed to provide a convenient step into your vehicle, while rock rails prioritize protecting your vehicle's underbody during off-road adventures. Each option has distinct characteristics that make it better suited for specific needs and driving conditions.
Understanding Running Boards
Running boards are typically wider and run the full length between the wheel wells, offering a broad, stable platform for stepping in and out of your vehicle. They often integrate seamlessly with the vehicle's body lines, providing a more finished, factory-installed look. While their primary function is to assist with entry and exit, they can offer a minor degree of protection against road debris kicked up by your tires.
- Appearance: Often integrated and sleek, enhancing the vehicle's aesthetic.
- Functionality: Provide a wide, continuous step, especially useful for children and older passengers.
- Protection: Limited protection against minor road debris and door dings.
- Clearance: Generally reduce ground clearance more than side steps due to their width and mounting style.
Exploring Side Steps
Side steps, sometimes called nerf bars, are generally narrower than running boards and often feature individual step pads at each door. They tend to have a more rugged or utilitarian appearance, though many modern designs offer a sleek look. Like running boards, their main purpose is to make getting into and out of taller vehicles easier. They typically offer slightly better ground clearance compared to most running boards, as they are less intrusive.
- Appearance: Can range from rugged to sleek, often with distinct step pads.
- Functionality: Offer a secure step at each door, often with textured surfaces for grip.
- Protection: Similar to running boards, they offer minimal protection from road debris.
- Clearance: Generally provide slightly better ground clearance than running boards.
The Purpose of Rock Rails
Rock rails, also known as rock sliders, are built for a completely different purpose: protecting your vehicle's rocker panels and undercarriage from damage when off-roading. They are constructed from heavy-duty materials like steel and mount directly to the vehicle's frame, designed to withstand impacts from rocks, stumps, and other obstacles encountered on trails. While some rock rails incorporate a small step surface, their primary role is protection, not entry assistance.
- Appearance: Heavy-duty and robust, emphasizing durability and off-road capability.
- Functionality: Designed to slide over obstacles, protecting the vehicle's vulnerable undercarriage.
- Protection: Excellent protection against significant off-road impacts.
- Clearance: Can be designed to minimize impact on ground clearance, often tucked close to the body.
Key Differences and Considerations
Choosing between these options depends heavily on your vehicle's primary use and your lifestyle. If your main concern is making it easier for passengers to get into your Ram 1500 or Jeep Grand Cherokee, running boards or side steps are the way to go. If you frequently take your Jeep Wrangler or Ram Power Wagon off the pavement and onto challenging trails in the Globe area, rock rails are a critical upgrade for protection.

Fitment for Ram and Jeep Models
At Horne Chrysler Dodge Jeep Ram, we can help you find the perfect running boards, side steps, or rock rails for your Ram truck or Jeep SUV. Ram trucks, such as the Ram 1500, 2500, and 3500, can benefit greatly from running boards or side steps for easier access, especially for lifted models. For Jeep models like the Wrangler, Gladiator, and Cherokee, the choice often depends on whether the vehicle will primarily be used on pavement or for off-road adventures.
- Ram Trucks: Many owners choose running boards or side steps for convenience and a finished look. Options range from polished stainless steel to textured black finishes.
- Jeep SUVs: Wranglers and Gladiators often benefit from rock rails for serious off-roading, while side steps can be a good compromise for daily driving with occasional trail use. Grand Cherokee and Cherokee owners often opt for running boards or side steps for family convenience.
