Running Boards For A 2018 Chevy Silverado
The 2018 Chevy Silverado is a popular truck, known for its versatility and capability. One common aftermarket addition to this model is running boards, designed to enhance accessibility and provide added protection. This article delves into the technical specifications, engineering considerations, performance, and maintenance of running boards specifically for the 2018 Silverado, offering a comprehensive guide for automotive professionals.
Technical Specifications and Engineering Choices
Running boards for the 2018 Silverado come in a variety of materials, including aluminum, steel, and composite polymers. Aluminum running boards are lightweight and corrosion-resistant, making them a popular choice, particularly in areas with harsh winters and road salt. Steel running boards offer superior strength and durability, ideal for heavy-duty applications and off-road use. Composite boards prioritize weight savings and can be molded into complex shapes for improved aerodynamics and aesthetics.
The dimensions of running boards are crucial for proper fit and function. They typically span the length of the cab, providing a step-up point for both front and rear doors. Mounting brackets are a critical engineering element, usually constructed from heavy-gauge steel and designed to bolt directly to existing frame mounting points. The design must consider the vehicle's load capacity and the anticipated weight placed on the running boards. Finite element analysis (FEA) is often used in the design process to optimize the bracket's strength and minimize stress concentrations.
Surface texture is another important consideration. Non-slip surfaces, achieved through textured coatings, step pads, or integrated treads, are essential for safety, especially in wet or icy conditions. Some running boards incorporate LED lighting for improved visibility at night, requiring additional wiring and electrical considerations.
Real-World Performance and Alternatives
Running boards significantly improve accessibility to the 2018 Silverado's cab, particularly for individuals with limited mobility. They also help protect the rocker panels from road debris, mud, and scratches. Alternatives to traditional running boards include:
- Nerf bars/Step bars: These offer a more aggressive, off-road look and typically have a smaller stepping surface. They prioritize rock crawling protection over pure ease of entry.
- Powered Running Boards: These automatically deploy and retract when the doors are opened and closed, offering the ultimate in convenience and a clean, tucked-away look when not in use.
- Rock Sliders: Designed for extreme off-roading, they provide maximum protection for the rocker panels and frame but are not primarily designed for step-up assistance.
Pros of Running Boards: Increased accessibility, rocker panel protection, enhanced aesthetics, and added grip in slippery conditions.
Cons of Running Boards: Reduced ground clearance (especially fixed running boards), potential for mud and snow buildup, and can sometimes interfere with off-road capabilities.
The performance of running boards directly relates to their material, design, and installation quality. Poorly installed or low-quality running boards can bend, crack, or detach, posing a safety hazard.
Reliability Aspects and Maintenance Tips
Reliability depends largely on the quality of materials and construction. Aluminum and steel running boards generally offer excellent durability. Composite boards may be more susceptible to cracking in extreme temperatures or under heavy loads. The mounting brackets are the most critical component, as they bear the brunt of the weight. Inspect these brackets regularly for rust, cracks, or loose bolts.
Maintenance Tips:
- Regularly clean running boards with soap and water to remove dirt, mud, and road salt.
- Apply a protectant to prevent corrosion, especially on steel components.
- Inspect mounting brackets for tightness and corrosion. Tighten bolts as needed.
- Check for damage after off-road use or impacts.
Powered running boards require additional maintenance, including lubricating the hinges and motors. Consult the manufacturer's instructions for specific maintenance procedures.
Future Trends
Future trends in running board design include the integration of advanced materials like carbon fiber for increased strength and weight savings. Active suspension systems could be incorporated to automatically adjust the height of the running boards based on terrain and passenger needs. Furthermore, expect to see greater integration with vehicle electronics, such as sensors that detect obstacles and prevent the running boards from deploying into them. Aerodynamic optimization will also play a larger role, with designs aimed at minimizing drag and improving fuel efficiency.
The rise of electric trucks will also influence running board design. Expect to see more focus on weight reduction to maximize range and integration with battery packaging. The increasing popularity of overlanding and off-road modifications will drive demand for more rugged and adaptable running board options.
Forward-Looking Note
The automotive industry is undergoing a rapid transformation, driven by electrification, autonomous driving, and increasing connectivity. Automotive professionals must stay informed about the latest technologies and trends to effectively service and maintain modern vehicles. A deeper understanding of not only core mechanical components but also aftermarket accessories like running boards, is critical for providing comprehensive and reliable service to customers. Adaptability and a commitment to continuous learning are essential for success in this evolving landscape.
