### **Pros and Cons of buying a GM 87814101 Lower Cover (2021 2024 GMC Trucks)**

1. **OEM Quality and Fit** This part is a genuine General Motors (GM) replacement, ensuring a precise fit and compatibility with 2021 2024 GMC models like the Sierra, Savana, and Terrain. It avoids the risk of aftermarket parts that may not align perfectly, reducing the chance of leaks or misalignment.

2. **Durability and Longevity** GM s lower covers are designed to withstand heavy loads, road debris, and environmental exposure. A high-quality OEM part is less likely to fail prematurely compared to cheaper alternatives, potentially saving money on frequent replacements.

3. **Warranty Coverage** Purchasing from an authorized GM dealer or a reputable online retailer often includes a warranty (e.g., 12 60 months), providing peace of mind against manufacturing defects. This can be especially valuable if the part fails shortly after installation.

4. **Protection for Underbody Components** The lower cover shields critical parts like the fuel tank, exhaust system, and suspension components from rocks, mud, and road salt. A well-fitted cover extends the lifespan of these systems, reducing maintenance costs over time.

5. **Resale Value Impact** Maintaining OEM parts can positively influence a vehicle s resale value, as buyers often prefer vehicles with complete and original components. This is particularly relevant for commercial or fleet vehicles where reliability is paramount.

6. **Easier Installation** Since it s designed specifically for the vehicle, installation is typically straightforward, especially if you have basic mechanical skills or access to professional help. Aftermarket parts may require additional modifications or adjustments.

7. **Compatibility with GM Systems** The part integrates seamlessly with the vehicle s electrical and structural systems, reducing the risk of compatibility issues that can arise with non-GM alternatives.

1. **Higher Upfront Cost** OEM parts are more expensive than aftermarket alternatives. The price of the GM 87814101 lower cover may range significantly higher than generic replacements, which could be a barrier for budget-conscious buyers.

2. **Limited Availability Outside Dealerships** While available from authorized dealers, these parts may not be as widely stocked at independent auto parts stores or online marketplaces compared to aftermarket options. This could require ordering in advance or waiting for delivery.

3. **Potential for Overkill** For vehicles that are not heavily used in harsh conditions (e.g., light-duty personal trucks driven on paved roads), the added protection of an OEM lower cover may not be necessary. In such cases, a more affordable aftermarket cover could suffice.

4. **Weight Considerations** OEM parts are often heavier than aftermarket versions, which might slightly impact fuel efficiency or handling in performance-oriented vehicles. However, the difference is usually negligible for most applications.

5. **Installation Complexity** While designed for ease of use, some OEM parts may require specific tools or expertise to install correctly, especially if the vehicle has additional underbody components (e.g., exhaust systems, skid plates). DIYers without experience may need to hire a professional, adding labor costs.

6. **Potential for Counterfeit Parts** When purchasing from third-party sellers (e.g., eBay, Amazon, or unscrupulous online retailers), there is a risk of receiving counterfeit or refurbished parts that do not meet GM s quality standards. Always verify the seller s reputation and part authenticity.

7. **Environmental and Ethical Concerns** Some buyers may prefer aftermarket or recycled parts to reduce environmental impact or support sustainable manufacturing. OEM parts, while durable, contribute to the automotive industry s resource consumption.

### **Conclusion**

The GM 87814101 lower cover is a high-quality, reliable choice for 2021 2024 GMC vehicles, offering superior fit, durability, and warranty protection. It is ideal for buyers who prioritize long-term reliability, resale value, and peace of mind, especially in commercial or heavy-duty applications. However, the higher cost and limited availability may deter budget-conscious or casual buyers who can opt for aftermarket alternatives without sacrificing performance.

For most GMC owners who drive in demanding conditions or seek to maintain their vehicle s integrity, the OEM part is a worthwhile investment. Those on a tight budget or with less demanding driving needs might find a well-reviewed aftermarket equivalent to be a cost-effective compromise.

### **Recommendation**

- You prioritize OEM quality and warranty coverage.

- Your vehicle is used in harsh or heavy-duty conditions.

- You plan to keep the vehicle long-term and want to preserve its value.

- You have access to an authorized GM dealer or a trusted online retailer to ensure authenticity.

- You are operating on a tight budget and can find a highly rated aftermarket part with good reviews.

- Your driving conditions are mild (e.g., light-duty, paved roads only).

- You are comfortable with installation and willing to research the best aftermarket options.

For most GMC owners, the OEM part is the safer and more future-proof choice, balancing cost with long-term benefits. Always verify the seller s legitimacy and check for warranty details before purchasing.
