Do Running Boards Affect Ground Clearance?

Mar 5 2026

Short Answer
 
Yes, fixed running boards can slightly reduce ground clearance, while retractable (power) running boards maintain nearly full clearance when retracted. The impact depends on the style, mounting position, and intended use of your truck.
 
How Running Boards Impact Ground Clearance
 
Ground clearance refers to the distance between the lowest point of your vehicle and the ground. Traditional fixed running boards sit below the rocker panel, which can reduce side clearance by 2–5 inches depending on design.
 
However, not all running boards affect clearance the same way.
 
Fixed vs Retractable Running Boards
 
Fixed Running Boards
  • Pros:
    • Always available for stepping
    • Durable and simple
    • Lower cost
  • Clearance Impact:
    • Remain visible at all times
    • May hang slightly below frame
    • Can reduce breakover angle in off-road situations
Brands like Westin, LUVERNE, and Raptor Series offer rugged fixed options, some designed with tighter mounting for minimal clearance loss.
 
Retractable (Power) Running Boards
  • Pros:
    • Deploy when doors open
    • Retract when doors close
    • Maintain factory clearance when not in use
  • Clearance Impact:
    • Virtually no clearance reduction when retracted
    • Ideal for lifted or off-road builds
Brands such as Aries and Steelcraft offer power running boards that sit flush against the rocker panel when closed.
 
Off-Road Impact: What You Should Know
 
If you off-road regularly, clearance matters more.
 
For Light Trails:
 
Standard fixed boards are typically fine.
 
For Moderate Off-Roading:
  • Look for:
    • Tight-mount boards
    • Slight drop steps rather than full-length wide boards
For Serious Off-Road Use:
  • Retractable boards are best
  • Or consider rock sliders instead of running boards
  • Fixed boards can contact rocks during:
    • Steep inclines
    • Deep ruts
    • Tight breakover angles
Mounting Positions Matter
 
Not all boards mount the same way. Clearance depends on:
  • Frame-mounted vs body-mounted brackets
  • How far below the rocker panel they sit
  • Whether they include drop steps
Drop-step designs (common in lifted truck builds) intentionally sit lower to reduce stepping height, which increases usability but reduces clearance.
 
Best Options for Maximum Clearance
  • Power Running Boards
    • Best overall for maintaining clearance while keeping convenience.
  • Low-Profile Fixed Boards
    • Some Westin and Steelcraft designs sit closer to the body for minimal impact.
  • Aluminum Boards
    • Often lighter and designed with tighter fitment.
 
Who Should Worry About Clearance?
 
You should prioritize clearance if you:
  • Have a lifted truck
  • Frequently trail ride
  • Rock crawl or overland
  • Drive in deep snow or uneven terrain
For daily drivers, clearance reduction is typically minimal and not noticeable.
 
Final Verdict
 
Running boards can reduce ground clearance, but the impact is usually minor for street-driven trucks. If off-road performance is important, retractable running boards offer the best balance between accessibility and clearance.
 
FAQs
 
  • Q: How much ground clearance do running boards reduce?
    • A: Typically 2–5 inches depending on style.
  • Q: Are power running boards better for off-road use?
    • A: Yes, because they retract and restore factory clearance.
  • Q: Do drop steps reduce clearance more?
    • A: Yes, drop steps sit lower by design to make entry easier.
