Review GENUINE GM New Oem Emission Reduction Def Tank Shield fits 3500 2500HD 2017–2019

The **GM 84113564 Emission Reduction Deflector Tank Shield** is a precision-engineered aftermarket component designed exclusively for General Motors 2500HD and 3500HD heavy-duty diesel trucks built between the model years 2017 and 2019. This high-performance shield is a critical part of GM s emission reduction system, specifically tailored to enhance the efficiency and longevity of the diesel particulate filter (DPF) and diesel oxidation catalyst (DOC) by minimizing heat buildup and thermal stress. Crafted from durable, heat-resistant materials, the deflector tank shield is strategically positioned beneath the fuel tank to redirect airflow and dissipate excess heat away from the emission control components, thereby preventing premature clogging, thermal damage, or failure of the DPF and DOC. This innovative design ensures optimal engine performance while adhering to stringent EPA and CARB emissions regulations, making it an essential upgrade for fleet operators, towing enthusiasts, and off-road adventurers who demand reliability and compliance without sacrificing power. The shield s precise fitment and robust construction also contribute to improved fuel efficiency by maintaining consistent exhaust gas temperatures, reducing the frequency of costly regeneration cycles, and extending the service life of the entire emission system. Whether navigating heavy-duty hauling, extended highway cruising, or rugged terrain, this shield serves as a silent guardian, safeguarding your truck s emission components while upholding GM s engineering standards for durability and performance.

### **Pros and Cons of buying a GM 84113564 Emission Reduction Def Tank Shield (2017-2019 2500HD/3500HD)**

1. **OEM Quality and Fit** This is a genuine GM (General Motors) part, meaning it is designed to match the original specifications of your vehicle. It should fit perfectly without modifications, reducing the risk of installation issues.

2. **Improved Emissions Compliance** The tank shield is part of the emission reduction system, helping your truck meet regulatory standards. If your vehicle is failing emissions tests due to related issues, this part may resolve the problem.

3. **Durability** GM parts are generally built to last, especially for high-mileage trucks like the 2500HD/3500HD. A well-made shield should resist corrosion and wear over time.

4. **Compatibility with Aftermarket Upgrades** Since it s an OEM part, it should work well with other aftermarket emissions components, such as catalytic converters or exhaust systems, if you plan to modify your truck.

5. **Warranty Coverage** If purchased from an authorized GM dealer or a reputable supplier, this part may come with a warranty, providing peace of mind against defects.

6. **Prevents Future Issues** If the shield is failing or damaged, replacing it now can prevent more serious problems, such as exhaust leaks or catalytic converter damage, which could be costly to repair later.

7. **Easy Installation** As an OEM part, it should come with clear instructions, and many mechanics are familiar with its installation process, reducing labor time.

---

1. **Higher Cost Compared to Aftermarket Alternatives** GM parts are typically more expensive than aftermarket equivalents. If you're on a tight budget, you may find cheaper alternatives that offer similar performance.

2. **Potential for Counterfeit Parts** If buying from an untrusted seller (especially online), there s a risk of receiving a fake or low-quality part. Always verify the seller s reputation and authenticity.

3. **Limited Availability Outside Dealerships** While GM parts are widely available, some specialty suppliers or online marketplaces may not stock this specific part, requiring extra effort to source.

4. **Installation May Require Professional Help** Depending on your mechanical skills, installing the shield could be challenging, especially if it requires removing other components (e.g., exhaust sections). Professional labor may be necessary.

5. **Not Always Necessary for Performance** If your truck is running fine and passing emissions tests, replacing this part purely for preventive maintenance may not be justified unless there s a specific issue.

6. **Potential for Overkill** Some drivers may not experience any problems with the shield, making this an unnecessary upgrade unless emissions-related symptoms exist.

7. **Resale Value Impact** If you plan to sell the truck later, some buyers may prefer aftermarket parts for cost savings. However, OEM parts can also appeal to buyers who prioritize reliability.

---

The **GM 84113564 Emission Reduction Def Tank Shield** is a solid choice if you need an **OEM-quality replacement** to ensure proper emissions compliance, prevent future issues, or maintain warranty coverage. It is particularly valuable if your truck is failing emissions tests or showing signs of related problems (e.g., exhaust leaks, check engine lights).

However, if you're looking for a **budget-friendly alternative**, aftermarket parts may suffice, provided they meet the same specifications. The decision ultimately depends on whether you prioritize **reliability, warranty protection, and long-term performance** over cost savings.

- **Buy from an authorized GM dealer or a trusted supplier** to ensure authenticity and warranty coverage.

- **Check for symptoms** (e.g., rough idling, exhaust leaks, or emissions failures) before purchasing if the issue is elsewhere, this part alone may not solve the problem.

- **Consider aftermarket options** if budget is a concern, but verify that they meet GM s specifications.

- **Have a mechanic inspect the installation** if you re unsure about DIY work, especially for high-mileage trucks.

- **Only replace if necessary** if the truck is running well, this may not be a critical upgrade.

For most **2017-2019 2500HD/3500HD owners dealing with emissions or exhaust-related issues**, this is a **worthwhile investment** in reliability. However, weigh the cost against the actual need to avoid unnecessary expenses.
