How to Install Running Boards on Your Vehicle

Understanding Running Boards: What They Are and Why Vehicle Owners Install Them

Running boards are horizontal steps that attach to the sides of a vehicle, positioned between the wheels and typically spanning most of the vehicle's length. They serve as platforms that make it easier to reach cargo on roof racks, enter and exit taller vehicles, or access equipment mounted on the vehicle's exterior. Running boards come in several styles, each designed for different vehicle types and purposes.

The most common type is the tube-style running board, which features a simple metal tube or cylindrical bar running along the vehicle's side. These are popular for trucks and SUVs because they provide a clean look while offering functionality. Side step boards are wider platforms with textured surfaces, providing more foot space and better traction. OEM (original equipment manufacturer) running boards are designed specifically by vehicle manufacturers to match their vehicles precisely. Aftermarket running boards are third-party products that fit many vehicle models and often cost less than OEM options.

Vehicle owners typically install running boards for practical reasons. Parents with small children benefit from the reduced step height when loading kids into tall vehicles. People who frequently place items on roof racks find running boards make positioning loads safer and easier. Commercial vehicle operators use them for worker safety when accessing equipment. Off-road enthusiasts install them to improve entry and exit on rough terrain. Some owners simply prefer the aesthetic appearance that certain running board styles add to their vehicle.

Understanding the different types helps you determine which option suits your vehicle and needs. Take time to consider your primary reasons for installation—whether for safety, functionality, or appearance—as this guides your selection process. Running board materials vary significantly, affecting durability and maintenance requirements, which we explore in the next section.

Materials, Durability, and Maintenance Considerations

Running boards are manufactured from several materials, each with distinct characteristics regarding durability, appearance, and maintenance. Stainless steel is a popular choice for many aftermarket running boards because it resists rust and corrosion well. Stainless steel maintains a polished appearance with minimal maintenance, though it can require occasional polishing to remove fingerprints and water spots. A quality stainless steel running board can last 10-15 years or more with basic care.

Aluminum running boards are lighter than steel options and naturally resist corrosion. They typically cost less than stainless steel while still offering good durability. Aluminum boards work well for vehicles where weight reduction matters, such as fuel-efficient trucks. However, aluminum can scratch more easily than stainless steel and may show wear patterns over time. Aluminum running boards generally require regular cleaning with mild soap and water to maintain appearance.

Powder-coated steel offers an economical option and comes in various colors to match vehicle paint. This option combines steel's strength with a protective coating that resists scratches and weather. The powder coating typically lasts 3-7 years depending on climate and maintenance. In coastal areas with salt air or regions using road salt, powder-coated steel may develop rust at edges or where the coating chips. Plastic composite running boards have become increasingly common. These resist rust completely and require minimal maintenance—usually just occasional washing. However, they may not feel as substantial as metal options and can become brittle in extreme cold climates.

Practical takeaway: Evaluate your climate and maintenance preferences when selecting materials. Stainless steel suits areas with road salt or high moisture. Aluminum works well for weight-conscious owners in moderate climates. Powder-coated steel offers value in dry climates. Plastic composites suit owners who want minimal upkeep. Regardless of material, regular washing prevents dirt buildup and extends the lifespan of any running board by several years.

Measuring and Selecting the Right Running Board for Your Vehicle

Proper fitting is essential for both safety and appearance. Running boards must align correctly with your vehicle's profile, or they'll look awkward and may not function properly. The first step involves identifying your vehicle's exact make, model, and year, as these details determine which running boards fit properly. Check your vehicle registration or owner's manual for this information.

Measure your vehicle's length and the distance between wheel wells. Most running boards attach between the front and rear wheels, though some extend differently. Measure the height from the ground to your vehicle's rocker panel (the area where running boards attach) at the front wheel, center, and rear wheel. Many vehicles have slightly different heights at these points. Write down these measurements—they help when comparing options from different manufacturers.

Consider your vehicle's width at the mounting point. Most running boards are 5-7 inches wide, but some aggressive aftermarket styles are wider. A wider board provides more stability when standing, but a narrower board is easier to navigate around when walking past the vehicle. Think about your actual use. If children will frequently use it, a wider board improves safety. For commercial use where workers must move quickly along the vehicle's side, a standard width is often preferred.

Research whether running boards are available for your specific vehicle model. Manufacturers produce running boards for vehicles that represent large market segments. Popular pickup trucks have numerous options—sometimes 20 or more different styles from various manufacturers. Less common vehicle models may have only a few options, or possibly none designed specifically for that model. Online retailer websites and vehicle forum communities provide information about availability and fitment for your exact vehicle.

Practical takeaway: Create a specification sheet for your vehicle including make, model, year, current measurements, and your primary use case. Share this information when researching options. Many retailers offer fitment verification tools on their websites where you enter your vehicle information and see compatible running boards. Taking time to verify fitment prevents purchasing incorrect products that require return.

Tools, Materials, and Preparation Steps Before Installation

A successful running board installation requires the right tools and careful preparation. Most installations take 2-4 hours, depending on the complexity and your mechanical experience. Gather these tools before beginning: a socket set with wrenches in appropriate sizes (typically 10mm through 16mm), a cordless drill with bits for pilot holes, a torque wrench for fastening to specification, a tape measure, a straight edge or level, jack stands or ramps for vehicle elevation, and a helper to assist with positioning and holding components.

Review the manufacturer's installation instructions completely before starting. These instructions specify the exact fastening points, torque specifications, and any special preparation needed. Different running board styles require different attachment methods. Some bolt directly to existing holes in the vehicle's frame or rocker panel. Others require drilling new holes, which means marking precise locations. Some mounting systems use clamps that grip the vehicle's undercarriage. A few advanced systems integrate with existing mounting points designed into the vehicle when manufactured.

Prepare your work area by parking the vehicle on a level surface with good lighting. Clean the mounting area thoroughly with soap and water, then dry completely. If drilling new holes, mark the locations using the template provided (or create one from the instructions). Use a center punch to make a small indentation at each hole location—this prevents the drill bit from sliding across the surface. Before drilling, verify hole locations by measuring multiple times. It's better to spend an extra 10 minutes confirming than to drill incorrectly and damage the vehicle.

Check that all components are included in the package. Count bolts, brackets, and hardware—most manufacturers include a few extras for safety. Inspect components for defects or damage. Check that the running board itself is straight by placing it on a flat surface and looking for gaps. If you discover missing pieces or damage, contact the seller before proceeding.

Practical takeaway: Read instructions at least twice before starting work. Prepare a clean workspace with proper lighting. Gather all tools in one location. Verify that all components are present and undamaged. Have a helper available—some installation steps are easier and safer with two people. Taking 30 minutes for preparation typically prevents hours of troubleshooting later.

Step-by-Step Installation Process and Fastening Techniques

The installation process varies by running board type, but general procedures apply to most systems. Begin by elevating the vehicle using a jack and securing it with jack stands. Never work under a vehicle supported only by a jack, as jack failure creates serious safety hazards. Elevation provides space to work on mounting brackets without interference from ground or wheel wells.

Locate the mounting points according to manufacturer instructions. For vehicles where running boards bolt to existing holes, align the bracket with these holes first. For vehicles requiring new holes, use the template or measurements to mark locations precisely. Position a backing plate or reinforcement inside the rocker panel before drilling if your vehicle requires it. Backing plates distribute pressure across a larger
