For towing enthusiasts, the Ford Power Stroke 6.7-liter engine is a powerhouse built to deliver outstanding torque, impressive durability, and exceptional towing capacity. While this engine is robust straight from the factory, the aftermarket world offers various upgrades that can enhance its performance, efficiency, and reliability, especially under heavy towing conditions. Here’s a closer look at the best upgrades for towing enthusiasts who want to get the most out of their Power Stroke 6.7.
1. Aftermarket Exhaust Systems
A high-performance exhaust system improves the engine’s efficiency by enhancing airflow and reducing backpressure. For towing, this translates to lower exhaust gas temperatures (EGTs) and improved fuel economy. Consider upgrading to a stainless-steel turbo-back or DPF-back exhaust system to handle the increased workload effectively.
Benefits:
- Reduces EGTs under heavy loads.
- Enhances overall engine performance.
- Improves sound without excessive noise.
2. Upgraded Intercoolers
Towing heavy loads generates significant heat. An upgraded intercooler ensures cooler, denser air reaches the engine, improving combustion and preventing power loss caused by heat soak.
Key Features:
- Larger core for increased cooling capacity.
- Better heat dissipation under sustained towing.
- Improved durability compared to stock intercoolers.
3. Tuning and Programmers
Custom tuning or performance programmers allow for tailored engine mapping that prioritizes torque and fuel efficiency under towing conditions. Many tuners provide specific towing modes that optimize the transmission shift points and adjust the power delivery curve.
Considerations:
- Use tuning devices compatible with emissions regulations in your area.
- Look for tuners offering real-time engine monitoring for better insights during long hauls.
4. Heavy-Duty Transmission Upgrades
Towing stresses the transmission as much as the engine. Upgrades like high-performance torque converters, transmission coolers, and reinforced clutches can handle the added strain and ensure smooth operation under load.
Benefits:
- Increases transmission longevity.
- Reduces the risk of overheating during towing.
- Provides smoother gear shifts for better drivability.
5. Turbocharger Upgrades
For those frequently towing at maximum capacity, upgrading to a larger or more efficient turbocharger can provide a significant boost in power and torque. Coupled with proper tuning, this can make a noticeable difference in towing performance.
Advantages:
- Higher power output at lower RPMs.
- Better response under heavy loads.
- Increased efficiency in challenging conditions.
6. Suspension Enhancements
Heavy-duty towing impacts your truck’s suspension. Upgrades like airbag suspension kits or heavy-duty leaf springs can stabilize your ride and improve towing capacity.
Key Improvements:
- Reduces sag and enhances ride quality.
- Stabilizes the vehicle under heavy loads.
- Provides adjustability for different towing scenarios.
7. Fuel System Upgrades
A high-capacity fuel pump or upgraded injectors can ensure consistent fuel delivery to meet the increased demands of towing. Pair this with a fuel filtration system to protect against contaminants.
Why It Matters:
- Improves engine reliability during extended towing.
- Supports higher performance tuning.
- Reduces wear on critical fuel system components.
8. Enhanced Cooling Systems
Towing generates significant heat, not just in the engine but throughout the vehicle. Upgraded radiators, coolant filters, and additional oil coolers can prevent overheating and maintain optimal performance.
Cooling System Upgrades Include:
- Larger-capacity radiators for better heat exchange.
- Auxiliary oil coolers for engine and transmission longevity.
- Improved water pumps for consistent coolant flow.
9. Brake System Upgrades
Stopping power is just as important as pulling power when towing. Upgraded brake pads, rotors, and even auxiliary braking systems like exhaust brakes can provide better control and safety.
Recommended Upgrades:
- Heavy-duty brake pads with better heat tolerance.
- Slotted or drilled rotors for improved cooling.
- Exhaust or engine braking systems for additional stopping power.
10. Monitoring and Gauges
Installing aftermarket gauges or a digital monitoring system can provide real-time data on key metrics like EGTs, transmission temperature, and boost pressure. This information is invaluable for maintaining optimal performance during towing.
Commonly Monitored Metrics:
- Exhaust gas temperature.
- Coolant and oil temperature.
- Transmission fluid temperature.
- Boost pressure.
Final Thoughts
The Ford Power Stroke 6.7 is already an exceptional engine for towing, but these upgrades can take its performance to the next level. By investing in the right enhancements, you can tow with confidence, ensuring your truck remains reliable, efficient, and powerful for years to come. Always prioritize compatibility and consult with experienced professionals to tailor upgrades to your specific towing needs.
