For U.S. truck owners seeking to improve accessibility and add a rugged aesthetic to their vehicles, installing a set of running boards—also known as nerf bars—can be a straightforward yet highly impactful modification. This guide, drawing from multiple verified technical instructions and installation procedures, provides a detailed, step-by-step approach to installing running boards. Though the examples focus on specific models and components, the general principles apply broadly to most trucks and running board kits.
General Installation Overview
The installation of running boards typically involves securing brackets to the vehicle’s frame and then fastening the boards to the brackets. A critical part of the process is aligning the running board bolts with the bracket slots and ensuring all hardware is tightened securely once the desired positioning is achieved. The process is largely mechanical, requiring basic hand tools and attention to detail to ensure both functionality and safety.
Required Tools and Materials
Before beginning the installation, gather the following tools and materials. These are commonly referenced across multiple installation guides:
- Ratchet and socket set
- Box end wrenches
- Safety glasses and gloves
- Creeper or padded mat (optional)
- Running board kit (including brackets, bolts, and washers)
- Optional: Sawzall or metal cutting blade (for bumper removal in some cases)
The tools listed are standard for automotive installations and ensure that the user can complete the process safely and efficiently.
Step-by-Step Installation Process
1. Prepare the Vehicle
Before installing the running boards, it is essential to prepare the vehicle for the modification. This includes:
- Ensuring the vehicle is on a level surface and the parking brake is engaged.
- Disconnecting the battery if necessary to prevent accidental activation of electronic systems.
- Removing any existing running boards or trim that may interfere with the installation.
For vehicles with a suspension lift, additional steps may be required to ensure the running boards align properly with the new ride height. Some kits include adjustable tabs or spacers to accommodate different vehicle configurations.
2. Install the Brackets
Most running board kits come with pre-fabricated brackets that are designed to mount to the vehicle’s frame. The brackets typically feature slots to allow for positional adjustments before final tightening. The following steps should be followed:
- Position the brackets according to the manufacturer's instructions. The number of brackets required may vary depending on the truck's year, make, model, and cab size.
- Align the running board bolts with the bracket slots. At this stage, the bolts should be left finger-tight to allow for further adjustments.
- Repeat the process on the opposite side of the vehicle. It is important to ensure both sides are symmetrical and properly aligned before proceeding to the next step.
3. Secure the Running Boards
Once the brackets are in place, the running boards can be attached to the brackets. This involves:
- Placing the running boards onto the brackets. Ensure the threaded portion of the bolts faces downward to prevent interference with other components.
- Tightening the bolts to secure the boards in place. Begin with a snug fit and then use the appropriate tools to tighten the bolts to the manufacturer’s recommended torque specifications.
- Checking for hardware tension and making any necessary adjustments. Periodic re-tightening may be required in the initial weeks following installation to ensure the hardware remains secure.
4. Final Adjustments and Testing
After the running boards are installed, a final inspection and test are recommended to ensure everything functions as intended:
- Check the hardware for any signs of looseness or misalignment.
- Test the boards by stepping on them to confirm they are stable and secure.
- Periodically re-tighten the bolts as needed, especially in the first few months after installation when settling can occur.
Some kits may also require the installation of additional components such as underbelly sliders or bumper reinforcements. These are typically included in the kit or referenced in the manufacturer’s instructions.
Installation Considerations for Specific Kits
While the general process for running board installation is consistent across most kits, some models may have unique requirements. For example:
- Adjustable ride height systems: If the vehicle is equipped with an air suspension or adjustable leveling system, the running boards must be installed after the final ride height has been set. This ensures the boards align properly with the ground and do not interfere with the suspension components.
- Lifted vehicles: For trucks with a suspension lift, the installation may require additional hardware such as spacers or extended bolts to accommodate the increased ride height. Always refer to the manufacturer’s instructions for specific recommendations.
- Compatibility with other components: In some cases, the installation of running boards may affect the fitment of other components such as exhaust systems, skid plates, or rock sliders. It is important to verify that there is no interference and that all systems function as intended after installation.
Troubleshooting Common Installation Issues
During the installation process, users may encounter common issues such as:
- Misaligned bolts: If the bolts do not align with the bracket slots, it may be necessary to adjust the positioning of the brackets or use a coarse round file to ovalize the holes slightly.
- Hardware interference: In some cases, the bolt heads may come into contact with the vehicle’s body or doors. If this occurs, it may be necessary to use only flat washers instead of lock washers to prevent contact.
- Noise from suspension components: If the installed running boards or related components (such as spring cones or sway bar brackets) begin to produce noise during vehicle operation, it may indicate contact between moving parts. In such cases, the components can be adjusted using tools like a crescent wrench to create clearance and reduce noise.
Safety and Compliance
When installing running boards, it is important to follow all safety guidelines and ensure the installation complies with local regulations. Some key considerations include:
- Use of safety equipment: Always wear safety glasses and gloves to protect against debris and sharp edges during the installation process.
- Proper torque specifications: Over-tightening or under-tightening bolts can lead to hardware failure or instability. Always follow the manufacturer’s torque recommendations.
- Structural integrity: Ensure that the brackets and mounting points are strong enough to support the weight of the user and any additional hardware.
- Post-installation inspection: After installation, inspect the running boards for any signs of wear, looseness, or damage. Address any issues immediately to prevent accidents or further damage.
Conclusion
Installing running boards is a practical and rewarding modification that enhances both the functionality and appearance of a vehicle. By following the step-by-step process outlined in this guide—ranging from bracket installation to final adjustments—users can ensure a secure and effective installation. The use of appropriate tools, attention to detail, and adherence to safety guidelines are key to achieving a successful outcome. Additionally, understanding the specific requirements of the running board kit and the vehicle’s configuration can help avoid common pitfalls and ensure long-term reliability.
For users seeking further assistance or clarification on specific components, manufacturer documentation and technical support resources are valuable tools. By combining hands-on installation with a clear understanding of the process, most users can complete the task efficiently and confidently.
