Introduction
The COMNOVA running boards are a high-quality, durable alternative to factory-installed steps, designed specifically for 2019–2024 Chevy Silverado and GMC Sierra 1500 models, as well as 2022–2024 2500 and 3500 regular cab variants. These side steps offer a secure, slip-resistant platform for entering and exiting the vehicle, while also enhancing the truck’s appearance and functionality. The product is built with T304 stainless steel and UV-resistant plastic, offering a blend of strength and aesthetics. Installation is designed to be straightforward, requiring no drilling or cutting, and the running boards feature a patented slider design for customizable positioning.
This article provides a detailed overview of the installation process, technical specifications, user experiences, and key features of the COMNOVA running boards, based solely on information from verified sources.
Installation Overview and Key Considerations
Installation of the COMNOVA running boards is designed to be a bolt-on process, requiring minimal tools and no modification to the vehicle’s structure. The product comes with all necessary mounting hardware and detailed instructions. The following steps outline the general installation process as described in the source material:
1. Preparation and Positioning
Before installation, users are advised to lower the running boards and walk around on them to identify any potential rubbing or clearance issues. Specifically, attention should be paid to the pinch welds (the seam between the body and door of the truck). The running boards should maintain a clearance of approximately ¾ of an inch from the end caps to the pinch welds to prevent interference during vehicle movement.
The patented slider design allows the user to adjust the position of the running boards forward or backward after the mounting brackets have been installed. This feature is particularly useful for achieving a precise fit and ensuring that the running boards do not rub against the truck’s body during normal use or off-road activity.
2. Mounting the Brackets
The first step in installation is to mount the brackets under the truck. This involves aligning the brackets with the factory mounting holes and securing them with the provided hardware. As noted in multiple sources, the brackets align precisely with the existing holes, eliminating the need for drilling or cutting.
However, some users reported issues with carriage bolts not fitting properly. In one case, the manufacturer included metric carriage bolts, which were slightly loose in standard holes. Users are advised to check the fit of the bolts before proceeding and to replace them with appropriately sized ones if necessary.
3. Attaching the Running Boards
Once the brackets are securely mounted, the running boards are attached using the same hardware. The running boards are designed to slide into place and are secured with bolts that prevent lateral movement. The process is described as straightforward, with one user noting that the installation could be completed without difficulty.
It is important to ensure that the running boards are fully seated and that all bolts are tightened to the appropriate torque specifications. The product documentation does not specify torque values, so users are encouraged to follow standard automotive fastening practices.
4. Final Adjustments and Testing
After installation, the running boards should be tested for stability and clearance. Users are advised to bounce up and down on the steps to identify any wobbling or misalignment. Any rubbing against the truck body should be corrected by adjusting the position of the running boards using the slider design.
One user emphasized the importance of reapplying undercoating in areas where the factory coating was removed to prevent rust and corrosion. This is particularly relevant for trucks used in rugged or off-road conditions.
Technical Specifications and Design Features
The COMNOVA running boards are engineered to offer both functionality and durability. The following are key technical specifications and design elements based on the provided source material:
1. Material and Construction
- Frame Material: T304 stainless steel. This material is known for its high strength, corrosion resistance, and ability to withstand heavy use.
- Step Surface: UV-resistant plastic with a non-slip texture. This provides a secure footing for users and is designed to resist fading or degradation from prolonged exposure to sunlight.
- Width: 6 inches. This width is considered optimal for providing a stable platform for entering and exiting the vehicle, especially for users with large boots or those wearing safety gear.
- Weight Capacity: The running boards are rated to support up to 500–550 pounds. This makes them suitable for heavy use, including supporting the weight of two individuals standing on the steps at the same time.
2. Mounting and Compatibility
- Mounting Style: Bolt-on installation with factory holes. No drilling or cutting is required.
- Mounting Points: Four per side. This is more than the standard three used by many competitors, offering increased stability and support.
- Compatibility: The running boards are specifically designed for the following models:
- 2019–2024 Chevy Silverado
- 2019–2024 GMC Sierra 1500
- 2022–2024 2500 and 3500 Regular Cab
3. Design Innovations
- Patented Slider Design: This feature allows users to adjust the position of the running boards forward or backward after installation. This ensures a custom fit and eliminates potential rubbing or clearance issues.
- Anti-Rub Design: The running boards are designed to sit below the rocker panels, reducing the risk of interference during normal driving or off-road use.
- Finish Options: The running boards are available in jet black, offering a bold and aggressive appearance that enhances the truck’s overall look.
User Experiences and Reviews
Multiple user reviews highlight the ease of installation, durability, and overall performance of the COMNOVA running boards. These experiences provide valuable insights into the product’s real-world application and functionality.
1. Installation Feedback
Users consistently report that the installation process is straightforward and does not require special tools or expertise. The use of factory mounting holes eliminates the need for drilling, and the included hardware is sufficient for most installations.
However, some users noted that the carriage bolts included in the kit may not be a perfect fit. One reviewer mentioned that the bolts were too small, requiring replacement with standard-sized ones. This is an important consideration for users who want to ensure a secure and long-lasting installation.
2. Performance and Durability
The COMNOVA running boards are praised for their durability and ability to withstand heavy use. One user described the steps as being “the heaviest I have helped install,” with each step weighing 75 pounds. This weight is attributed to the high-quality stainless steel construction, which is designed to resist bending or deformation from off-road impacts.
The running boards are not marketed as rock sliders, but their robust construction makes them suitable for light off-road use. Users who engage in overlanding or rock crawling note that the steps provide a stable platform for accessing the vehicle and its roof rack.
The product is also rated to support up to 500–550 pounds, making it suitable for heavy use in both urban and off-road environments. This weight capacity is particularly relevant for users who may need to step onto the running boards while carrying gear or equipment.
3. Aesthetic and Functional Enhancements
The COMNOVA running boards are noted for their ability to enhance the appearance of the truck. The jet-black finish and sleek design give the vehicle a more aggressive and premium look. One user mentioned that the steps made the truck look like a higher-priced model, significantly improving its overall presentation.
The non-slip plastic step surface is also praised for its functionality. It provides a secure footing for users and is designed to resist wear and fading from prolonged exposure to the elements.
4. Packaging and Quality Control
The packaging of the running boards is described as robust and well-organized. The steps are wrapped in Styrofoam and sealed in heavy plastic to prevent damage during shipping. The hardware is stored in a heat-sealed bag, ensuring that it remains secure and organized.
One user noted that the packaging demonstrated a commitment to quality and customer satisfaction, as it was designed to protect the product from even the most severe shipping conditions.
