Review FORD TRUCK Sd 6.7l Throttle Body fits F550SD F550 2019

The **Ford 337 Ford F-550 Super Duty 6.7L Power Stroke Throttle Body (FD8819)** is a high-performance, precision-engineered component designed exclusively for the iconic **Ford 6.7L Power Stroke diesel engine**, found in the **F-550 Super Duty** lineup. This throttle body is a critical part of the **EcoBoost diesel system**, serving as the gateway for air intake into the engine, where it plays a pivotal role in optimizing fuel efficiency, power delivery, and emissions compliance. Crafted from durable **aluminum alloy**, the throttle body is engineered to withstand the rigorous demands of heavy-duty trucking, towing, and off-road applications while maintaining structural integrity under extreme operating conditions. Its **integrated electronic throttle control (ETC)** system ensures seamless integration with the engine s **EFI (Electronic Fuel Injection)** and **turbocharging** components, allowing for precise modulation of airflow based on real-time engine demands. The **dual-stage throttle design** enhances responsiveness, particularly in low-RPM scenarios, while the **sealed gasket and mounting hardware** guarantee a leak-free installation, preventing air leaks that could compromise performance or trigger check engine lights. Whether used in **original equipment applications** or as a **replacement part** for restored or modified Power Stroke engines, this throttle body is a testament to Ford s commitment to balancing **torque, efficiency, and reliability** in its heavy-duty diesel lineup. For fleet operators, towing enthusiasts, or performance-minded truck owners, this component is an essential upgrade for maintaining peak engine health and maximizing the **6.7L s legendary 400 lb-ft of torque** in demanding applications.

### **Pros and Cons of Buying a 1995 Ford F-550 Super Duty with a 6.7L Power Stroke Diesel (FD8819, F550SD, Throttle Body Issue)**

#### **Pros**

1. **Reliability and Durability** The 6.7L Power Stroke (pre-2003) is known for its robustness and longevity when properly maintained. Many units easily exceed 300,000 miles with basic upkeep.

2. **Strong Resale Value** Ford Super Duty trucks, especially the F-550, hold their value well compared to many other heavy-duty trucks. The 6.7L engine is still sought after in the used market.

3. **High Torque Output** The 6.7L produces around **300 350 lb-ft of torque**, making it well-suited for towing, hauling, and off-road use. This engine was designed for heavy-duty work.

4. **Proven Performance** The throttle body issue (common in early Power Strokes) is well-documented, meaning parts and fixes are widely available. Many owners have successfully addressed it without major engine damage.

5. **Lower Fuel Costs** Diesel fuel is generally cheaper per gallon than gasoline, and the 6.7L offers excellent fuel efficiency for its class (around **8 12 MPG combined**, depending on load).

6. **Aftermarket Support** The 6.7L has a strong aftermarket presence, with upgrades (turbochargers, fuel systems, exhaust) readily available for those looking to modify the engine.

7. **Heavy-Duty Chassis** The F-550 Super Duty was built for commercial and industrial use, meaning the frame, suspension, and drivetrain are designed for extreme loads.

8. **Availability of Parts** Since this is an older model, parts (especially for the 6.7L) are still widely stocked by dealerships and specialty shops.

---

#### **Cons**

1. **Throttle Body Issue (Most Critical)** The **throttle body in the early 6.7L Power Stroke (pre-2003) is prone to failure**, often leading to **no-start or rough-idle conditions**. While it can be replaced (costing **$500 $1,500** depending on labor), it s a known weak point.

2. **Emissions Compliance (Smog Issues)** The 6.7L (especially pre-1998) does not meet modern emissions standards, meaning it **cannot be registered in many states** for on-road use. Some states allow it for **agricultural/commercial use only**, requiring special permits.

3. **Fuel System Wear** The **fuel injectors, fuel pump, and lift pump** in older 6.7Ls can fail, leading to **hard starts, stalling, or complete engine failure**. Replacing these can be expensive (**$1,500 $3,000 **).

4. **Turbocharger Reliability** The **turbocharger in the 6.7L is not as robust as later models** and can fail, causing **loss of power or catastrophic engine damage** if not addressed quickly.

5. **Transmission Issues (4R100/4R70W)** The **4R100 (early) and 4R70W (later) transmissions** in these trucks can develop **slipping, rough shifting, or solenoid failures**, requiring **$2,000 $4,000 ** in repairs.

6. **Electrical Problems** Older Ford trucks (especially pre-2000) suffer from **failing alternators, starter motors, and wiring issues**, which can be frustrating to diagnose and repair.

7. **High Maintenance Costs** While the engine is durable, **regular maintenance (fuel filters, glow plugs, turbo cleaning, etc.) is essential**. Neglecting these can lead to **expensive repairs**.

8. **Limited Modern Tech** Unlike newer trucks, this model lacks **modern diagnostics, advanced safety features, and fuel efficiency improvements**, making it less practical for daily driving.

9. **Resale Depreciation** While it holds value better than many trucks, the **emissions restrictions and age** mean it will never be worth as much as a newer diesel or even a modern gasoline truck.

10. **Noise and Vibration** The 6.7L is **loud and can vibrate excessively**, especially when cold. This can be an issue for urban or residential use.

### **Ending Conclusion**

The **1995 Ford F-550 Super Duty with a 6.7L Power Stroke** is a **strong, capable workhorse** that excels in **towing, hauling, and off-road use** but only if **properly maintained**. The **throttle body issue is the biggest concern**, but if addressed early, the engine can last **200,000 miles**. However, **emissions restrictions, high repair costs, and outdated technology** make it a **less ideal choice for daily driving or urban use**.

If you **plan to use it exclusively for commercial, agricultural, or off-road purposes** (where emissions laws are relaxed), and you re **prepared for potential repairs**, this truck can be a **great investment**. If you **need a reliable daily driver or on-road vehicle**, a **newer diesel (2011 Power Stroke) or even a well-maintained gasoline truck** would be a better long-term choice.

---

### **Recommendation**

- You need a **heavy-duty work truck** for **towing, construction, or farming**.

- You **inspect the throttle body, fuel system, and transmission** thoroughly before purchasing.

- You re **willing to budget for potential repairs** (especially throttle body, injectors, and turbo).

- You **don t mind emissions restrictions** and can operate it under **agricultural/commercial exemptions**.

- You need a **daily driver** or **on-road vehicle** due to emissions issues.

- You **can t afford major repairs** (throttle body, transmission, fuel system).

- You **prefer modern technology, fuel efficiency, or lower maintenance costs**.

- You **don t have a dedicated space** for storage and maintenance.

**Best Alternative:** If you want a **more reliable, emissions-compliant diesel**, consider a **2011 Ford Power Stroke (6.7L or 7.3L)** or a **Ram 6.7L Cummins** (if emissions laws allow). If you need a **budget-friendly work truck**, a **well-maintained 2000 2005 F-550 with a 7.3L** (less throttle body issues) could be a better balance.
