If you’ve recently purchased or are planning to buy a truck, especially a full-size pickup like a Ford F-150, Chevrolet Silverado, or Ram 1500, you may be considering adding running boards. These accessories can make it easier to access your vehicle, improve its aesthetics, and even protect the body from road debris. But before you start shopping for a set, one of the most important questions to address is: Are trucks pre-drilled for running boards?
This article dives deep into this question, exploring how different manufacturers handle pre-drilling, what to look for on your specific model, and how to install running boards if your truck does not come pre-drilled. Let’s start with the basics.
What Are Running Boards and Why Do People Install Them?
Running boards are the step-like accessories mounted along the sides of a vehicle, typically along the lower body panels. They serve multiple purposes:
- Improved Access: For lifted trucks or models with high ground clearance, running boards provide a safer and easier way to climb into the cabin.
- Aesthetic Appeal: Many truck owners prefer the clean, customized appearance that well-matched running boards offer.
- Protection: Quality running boards can shield the doors, rocker panels, and undercarriage from dirt, water, rocks, and other elements.
In essence, they offer both functional and cosmetic benefits. But to install them, you need mounting points — and that’s where the concept of “pre-drilled” trucks comes in.
Do Trucks Come Pre-Drilled for Running Boards?
The short answer is: Sometimes — but not always.
Whether a truck is pre-drilled for running boards depends on several factors:
- Manufacturer: Some major pickup truck manufacturers, like Ford, Chevrolet, and Toyota, have models that come with factory-mounted holes for optional accessories such as running boards or nerf bars.
- Trim Level: Higher trims or packages (e.g., Crew Cab, Limited, Trail Boss, or TRD Pro) might include pre-drilled mounting points for accessories.
- Year and Model: Newer models may have evolved designs influenced by consumer demand for easy accessory installation.
In many modern trucks, you’ll find threaded mounting points or small holes already in place — but not always full-size holes intended specifically for running board bolts. Instead, they might be covered by small plastic plugs or painted over. These are designed for accessories, including running boards.
Examples of Truck Models with Pre-Drilled Running Board Mounts
Let’s take a look at a few examples of truck models from major brands that commonly feature running board-ready mountings:
| Manufacturer | Model | Common Pre-Drill Locations | Additional Notes |
|---|---|---|---|
| Ford | F-150 | Rocker panels, wheel well area | Ford often includes factory mounting points, especially in crew cab and FX4 trims. |
| Chevrolet | Silverado 1500 | Frame rails and frame pockets | Pre-drilled for modular bumper systems and side steps; check factory access panels. |
| Ram | 1500 | Rocker panel areas and frame | Ram trucks often include holes for step installation, though plugs may need cutting or removal. |
| Toyota | Tundra | Outer rocker panels | New Tundras have pre-prepared mounting points for Nerf-style steps and running boards. |
In the table above, it’s evident that pre-drilling is more common in certain brands, especially for higher trims. However, the way these truck manufacturers implement it varies significantly.
How to Check If Your Truck Is Pre-Drilled for Running Boards
If you’re already the owner of a pickup or shopping around for one, here’s how to verify if your specific truck is pre-drilled:
- Inspect the Rocker Panels: These are the lower sections between the front and rear wheels. Look for small plastic plugs or round indentation marks indicating potential holes.
- Look Behind Plastic Trim: Some trucks hide mounting points behind removable panels near the frame rails or underbody.
- Check Factory Documentation: Review the vehicle’s specifications, body diagrams, or service manuals, which often call out OEM accessory mounting points.
- Consult Online Forums or Dealer Tech: Communities like F150.net or r/trucks have members who share photos and tips from owners with similar makes/models.
Tip: A quick way to begin is to remove some of the small plastic plugs underneath your doors. If you see clean threaded holes or pre-punched marks, you’re likely working with a truck that was factory prepared for step or running board installations.
What If Your Truck Isn’t Pre-Drilled?
Just because your specific truck doesn’t come with factory pre-drilled mountings doesn’t mean you can’t install running boards. However, it does add another layer of difficulty and cost, which involves drilling into the vehicle and finding the correct mounting positions.
There are two primary approaches to installation if your truck lacks mounting points:
1. Clamp-On Running Boards
Clamp-on (or bracket-mounted) running boards do not require drilling. They come with brackets designed to securely wrap around existing frame rails or body points, such as rocker panels or underneath the cab.
The installation process typically involves:
- Securing heavy-duty bracket clamps that tightly grip structural components.
- Adjusting alignment to ensure level and stable mounting, preventing flex or sagging.
- Using rubber or foam padding between clamps and frame to prevent vibration or damage.
These are especially popular for weekend DIYers or rental fleet trucks where permanent modifications aren’t preferable.
2. Drilling and Bolt-on Running Boards
Bolting running boards requires precise planning, mounting locations, and a careful drilling approach. Most manufacturers of running boards also provide full installation instructions and template guides for safe drilling procedures.
If you’re considering drilling, here are some basic steps:
- Use Running Board Manufacturer Templates: Many high-end running board kits include alignment jigs to guide where you should drill.
- Locate Structural Points: Use factory holes as anchors where possible (e.g., near the frame rails or body pinch seams).
- Double Check Measurements: Ensure symmetry across both sides of the truck.
- Use the Right Drill Bits: Always use heavy-duty bits suitable for drilling into steel or aluminum frames, depending on your truck’s body type.
Note: Drilling can void warranties if done outside of factory mounting points — so always review your warranty policy and follow the manufacturer’s recommendations.
The Impact of Wheelbase on Running Board Pre-Drilling
Another important consideration is the wheelbase of your truck — which can affect the length of the running board and whether you have enough mounting points.
Regular Cab vs. Crew Cab Trucks
- Regular Cab Trucks: These usually have the shortest wheelbase. They often feature only one or two mounting points at most, typically under the driver’s door. Running board installation options may be limited, though many companies make specific kits for these trims.
- Crew Cab Trucks: Regularly feature longer sides and often more mounting points in pre-drilled versions. These are ideal for full-length running boards.
Understanding your truck’s body style helps you choose the right type of running board or step bar — and whether the factory prepared it for installation.
How Running Board Types Fit With Factory Designs
Not all running boards are created equal, and some are more aligned with existing factory drilling:
1. OEM Running Boards
These are factory-issued accessories offered by the truck’s manufacturer. If a truck is designated as “running board-ready” in its options, this usually refers to OEM-specific hardware that can bolt right on with pre-installed factory mounts.
Benefits of OEM running boards include:
- Plug-and-play installation with no drilling
- Perfect color, shape, and design match with your truck
- Integrated LED lighting or puddle lamps (on select models)
However, OEM options can be quite costly and often lack customization beyond color and design.
2. Replacement (Aftermarket) Running Boards
These come from third-party companies like Westin, Rancho, AMP Research, and others. Their kits usually offer:
- More customization in texture, shape, finish
- Options like motorized retractable steps and adjustable position systems
- Better cost-efficiency than OEM products
While aftermarkets often include full installation guides, templates, and optional mounts for drilled vs. clamp-style installation, you must be careful to verify compatibility with your specific model, trim, and year.
3. Nerf Bars vs. Full-Length Boards
Also worth noting is the difference between nerf bars and full-length running boards:
| Feature | Nerf Bars | Full-Length Running Boards |
|---|---|---|
| Length | Shorter, door-level only | Full underbody span |
| Installation Complexity | Usually simpler, fewer points needed | More precise mounting, usually at 5+ points |
| Weight Capacities | Lightweight | Heavy-duty, designed for step access |
| Pre-drill Compatibility | Can oftentimes use standard pre-drill points | Requires multiple drilled or prepared mounting spots |
So, if your goal is complete running boards that extend down the length of the vehicle, pre-drilled mounting spots can ease the installation process significantly.
Considerations When Drilling Into Your Truck Frame
If you find that your truck doesn’t come with factory holes for running boards and you’re considering a bolt-on style, here are some important considerations:
Maintaining Structural Integrity
Your truck’s frame or body panels provide structural support. You must drill only where it’s safe — typically along the pinch seams, frame rails, or pre-identified body mounting junctions. Drilling in a poorly-placed spot can cause rust, weaken the body, and reduce resale value.
Rust and Corrosion Protection
Whenever drilling into a frame or body panel:
- Apply rust preventative coatings to exposed edges and screw holes.
- Seal all drilled points with undercoat or silicone where necessary.
This helps prevent long-term corrosion issues, especially in humid or snowy climates.
Warranty Concerns
While most modern warranties won’t void your entire coverage due to an aftermarket installation, some warranties specifically exclude modifications that affect the frame or body panels.
If you’re still under warranty:
- Document factory condition before drilling — take photos for dispute resolution.
- Stick to manufacturer-recommended templates to avoid liability issues.
Making Sense of Product Descriptions When Shopping for Running Boards
When selecting running boards, it’s essential to read product descriptions carefully. Here are some common label terms and what they mean:
- “Universal Fit” Running Boards: These will not have a pre-drilled setup specific to your make/model and will likely require custom mounting.
- “Vehicle-Specific Fit” Running Boards: These are engineered for your model, often with pre-drilled or clamp-on mounting compatibility.
- “Pre-drilled Kit Included”: Some kits offer DIY drilling guides or templates to make drilling easier, even if the truck isn’t prepped.
Always look for fit notes in detailed product descriptions and compare them to your model’s specifications.
Truck Models That Rarely Come Pre-Drilled for Running Boards
Not all trucks are equally equipped with pre-drilled mounting positions. Some models — particularly those from import brands or older domestic versions — rarely come ready for running board installation.
Examples:
- Nissan Titan – Not factory-prepared for running board installations on most trims.
- Older GM Trucks (e.g., 2006-2013 models) – Lack consistent mounting locations across platforms.
- Jeep Gladiator – Designed for off-road use, and often skips factory mounting points for side steps.
For these models, clamp-on boards or custom drill-in mounts are almost always required.
Conclusion: Are Trucks Pre-Drilled for Running Boards?
In summary, many newer full-size trucks from major brands — especially Ford, Chevrolet, Ram, and Toyota — include pre-drilled and/or pre-plugged mounting locations for running boards, particularly on higher trims and body styles like Crew Cabs.
However, there’s no universal standard across all models. Some trucks from older model years, compact platforms, or import-made vehicles might not have pre-drilled mounts, meaning installation of bolt-in running boards involves extra work.
If you’re planning to install running boards:
- Check with the manufacturer for compatibility.
- Inspect underneath your truck doors for common mounting points or plug covers.
- Select a model and installation style (clamp-on or bolt-on) that aligns with your expertise and comfort with tools.
Ultimately, knowing whether your truck is pre-drilled for running boards helps you make better decisions about what kind of product to buy and how to safely install it. Spending a little time inspecting your undercarriage today could save you hours of frustration and unnecessary drilling tomorrow.
By staying informed and prepared, you’ll not only get the best functionality from your investment but also maintain your truck’s integrity and value over the long run.
Are all trucks pre-drilled for running boards?
Not all trucks come pre-drilled for running boards. Whether or not your truck has factory-drilled holes depends on the make, model, and trim level of the vehicle. Some manufacturers anticipate that buyers may want to add accessories like running boards and design their truck frames accordingly. However, this is not a universal practice, so it’s important to verify the specifics of your truck model before making a purchase or installation plan. Higher-end or more rugged trims may be more likely to include pre-drilled holes for such accessories.
To find out if your truck is pre-drilled, a good first step is to examine the truck’s frame rails and rocker panels for any pre-installed holes or markings. Alternatively, you can consult your owner’s manual or contact the manufacturer directly. If you purchase aftermarket running boards, many kits are designed to fit without the need for factory pre-drilling by using mounting brackets that attach to existing structural points or by requiring you to drill new holes during installation.
If my truck is not pre-drilled, can I still install running boards?
Yes, you can definitely install running boards even if your truck is not pre-drilled. Many aftermarket running board kits are universal or vehicle-specific and come with brackets and mounting hardware that allow for installation without relying on factory holes. These mounting systems typically secure to the truck’s frame or body by either using existing bolt points or by requiring drilling. The process may take a little more time and effort, but it can be done successfully with the right tools and instructions.
Before beginning the installation, it’s important to ensure that the running boards are compatible with your exact vehicle make, model, and year to avoid fitting issues. Most manufacturers provide detailed installation guides that walk you through the process. If you’re not confident in your ability to drill and mount the boards yourself, you can opt to have a professional mechanic or a 4×4 shop perform the installation. They have the tools and experience to install running boards cleanly and safely.
What are the benefits of factory pre-drilled holes for running boards?
Factory pre-drilled holes offer a few distinct advantages when installing running boards. First and foremost, they allow for a cleaner and more seamless installation, since you won’t have to drill new holes into your truck’s body or frame. This can also save time and reduce the risk of mistaken placement or misalignment. Additionally, factory-drilled holes are often positioned according to the manufacturer’s engineering standards, ensuring optimal structural integrity and compatibility with certain types of OEM or genuine brand-specific running boards.
Another benefit is the potential for a more aesthetically pleasing installation. Utilizing existing holes often results in a neater appearance with fewer exposed fasteners or modifications. Furthermore, if you’re using OEM-style running boards, pre-drilled factory points ensure a snug and secure fit. In some cases, using factory mounting points can also preserve your truck’s warranty, as altering the frame by drilling could void certain coverage—particularly in specific regions or with certain manufacturers.
How do I know if my truck has pre-drilled factory holes for running boards?
To determine if your truck has pre-drilled holes for running boards, you can start by visually inspecting the rocker panels and frame rails. Look for screw caps, round plugs, or small covers that might be hiding threaded holes. These are often placed in pairs and spaced evenly to match the mounting points of factory running boards. If you see a clean line of holes running along the side of your truck or covered by plastic plugs, there’s a good chance they are intended for this purpose.
If you can’t find visible indicators, you can consult your truck’s owner’s manual or contact a dealership’s parts department for confirmation. Online forums and videos related to your specific truck model or trim may also provide helpful insight from other owners with similar vehicles. Some aftermarket running board manufacturers also list compatibility information and installation requirements, which can help you determine whether drilling will be necessary for your particular truck.
Will drilling new holes in my truck for running boards void the warranty?
Drilling new holes in your truck to install running boards may affect your vehicle’s warranty, but it depends on the manufacturer’s policies and the type of warranty you have. Factory warranties typically protect against defects in materials and workmanship, so minor modifications like drilling for accessory mounting do not automatically void all coverage. However, if a warranty claim is directly related to damage caused by that modification—such as rust, stress cracks, or frame damage—it could be denied. It’s important to understand the terms and coverage exclusions of your vehicle warranty.
OEM warranties and extended warranties vary widely, so it’s a good idea to check with your dealership’s service department or review your warranty paperwork before drilling. Additionally, some manufacturers may offer accessory packages that include running boards, which are designed to fit without requiring extensive modifications. If you’re concerned about warranty implications, consider using no-drill mounting options or modular systems designed to bolt on without permanent alterations to your truck’s frame or body.
Are no-drill running boards a good option?
No-drill running boards can be an excellent option for many truck owners, particularly those who want a simpler and reversible installation. These boards use clamps, brackets, or existing mounting points to attach to the vehicle without the need for drilling. They are ideal for people who rent their vehicles, want to avoid permanent modifications, or lack the tools or skills required for drilling and securing hardware. No-drill options also tend to be easier to install at home, which makes them a popular choice for DIYers.
However, no-drill running boards may not offer the same level of rigidity or durability as drilled-in systems, especially on trucks that are subjected to off-road use or heavy stepping. If you’re planning to use the running boards regularly or for climbing in and out of your vehicle with gear, it’s important to select a high-quality no-drill system or consider a drilled installation for better long-term stability. Always check user reviews and installation instructions to ensure the board will suit your usage and provide the support you need.
What types of aftermarket running boards are available for trucks without pre-drilled holes?
Aftermarket running boards come in various styles designed specifically for trucks that lack pre-drilled holes. These include clamp-on, track-style, weld-on, and universal bolt-on models. Clamp-style boards attach to the door jamb or rocker panel without drilling, while universal bolt-on models utilize included brackets that can be mounted using either existing structure points or custom drilling. Weld-on options are typically more permanent but offer maximum durability and clean integration. Some brands specialize in kits tailored for specific truck models, ensuring a precise fit.
In addition to installation method, aftermarket running boards vary in materials, widths, and features. Common materials include aluminum alloy, steel, and composite blends, each offering trade-offs between weight, strength, and corrosion resistance. Some models integrate LED lighting or skid-resistant surfaces for added functionality. When shopping for running boards, it’s important to confirm compatibility with your truck’s body type and intended use, whether it’s daily commuting, off-roading, or cargo hauling. Always read product descriptions carefully and reach out to the manufacturer if you’re unsure which system is best for your truck.
