### **Pros and Cons of buying a 39179 99-06 Chevy Silverado 11-Piece Steel Rocker Panel Upper Kit**
#### **Pros:**1. **Enhanced Protection** The steel rocker panel kit provides robust reinforcement against impacts from rocks, debris, and minor collisions. This is particularly useful for off-road driving, construction, or daily use in rough terrain.
2. **Improved Durability** Steel is significantly stronger than stock aluminum or plastic rocker panels, reducing the risk of dents, cracks, or structural damage over time. This can extend the lifespan of the vehicle s lower body panels.
3. **Better Ground Clearance** The raised profile of the rocker panels helps prevent scraping against uneven surfaces, curbs, or rough pavement, which is beneficial for both on-road and light off-road applications.
4. **Aesthetic Upgrade** The kit offers a more aggressive, rugged appearance compared to stock panels, which can appeal to those who prefer a tougher, more customized look.
5. **Compatibility with Other Mods** Steel rocker panels often work well with other undercarriage modifications, such as skid plates, diff guards, or lift kits, providing a cohesive protection package.
6. **Resale Value Boost** For enthusiasts or commercial users, a well-maintained truck with reinforced rocker panels may hold its value better than one with stock panels, especially if it s used for heavy-duty or off-road purposes.
7. **Easier Repairs** Steel is generally easier to weld and repair than aluminum, which can be more expensive and time-consuming to fix if damaged.

#### **Cons:**1. **Weight Increase** Steel is significantly heavier than stock aluminum or plastic panels. This added weight can slightly reduce fuel efficiency and may affect handling, especially in larger trucks or when towing heavy loads.
2. **Potential for Rust** While steel is durable, it is susceptible to rust if not properly sealed or maintained, particularly in areas with salt, moisture, or harsh climates. Regular cleaning and rust protection treatments are necessary.
3. **Installation Complexity** Installing steel rocker panels often requires welding, which may not be a DIY-friendly project for everyone. Professional installation can add to the cost.
4. **Cost** High-quality steel rocker panel kits are more expensive upfront than aftermarket aluminum or plastic alternatives. The price can range from a few hundred to over a thousand dollars, depending on the brand and quality.
5. **Clearance Considerations** While the kit improves ground clearance, it may also reduce the space between the panels and other components (e.g., exhaust, suspension). Users must ensure there s no interference with other mods or stock parts.
6. **Potential for Overkill** For light-duty or primarily on-road use, the benefits of steel rocker panels may not justify the cost and weight. Plastic or aluminum kits might suffice for milder conditions.
7. **Maintenance Requirements** Unlike stock panels, steel rocker panels require regular inspection for dents, scratches, or rust. Neglecting maintenance can lead to long-term issues.

### **Conclusion:**The **39179 99-06 Chevy Silverado 11-Piece Steel Rocker Panel Upper Kit** is a strong investment for those who prioritize durability, off-road capability, or heavy-duty use. The steel construction offers superior protection against impacts and abrasions, making it ideal for trucks subjected to rough conditions, frequent off-roading, or commercial applications. However, the added weight, higher cost, and maintenance demands may not be justified for casual drivers or those who primarily use their truck on paved roads.
If you frequently drive on rough terrain, encounter debris, or want long-term protection for your rocker panels, the steel kit is a worthwhile upgrade. For lighter use, consider lighter alternatives like aluminum or plastic kits to balance cost and performance.

- You want maximum protection against impacts and abrasions.
- You re willing to invest in professional installation and maintenance to prevent rust.
- You prefer the aggressive look and don t mind the added weight.

- You re uncomfortable with the extra weight or potential maintenance hassles.
- You plan to modify the truck further and are concerned about clearance issues.
For most **off-road or commercial Silverado owners**, the steel rocker panel kit is a **strong recommendation** due to its durability and protection. For others, weigh the pros and cons carefully against your specific needs.
