When you own a Ford Powerstroke, you don’t just own a truck, you own a staple in the diesel industry, but every machine has weak points. The stock components on these trucks are often designed for comfort and cost efficiency, not the extreme durability and high performance that you want from your Powerstroke.

At CNC Fabrication, we believe in getting the most from your Powerstroke! That means replacing the factory weak links with components that are engineered to solve problems, not just replace them as a temporary fix. 

Whether you're looking to cure the dreaded stiction in your injectors, unlock hidden horsepower, or make your transmission bulletproof, we’ve curated a list of our most popular Powerstroke upgrades that our customers swear by.

1. S&B Cold Air Intakes

An engine is an air pump. If you want more power, you have to get more air in and more exhaust out. The stock airbox is restrictive, often pulling warm air from the engine bay.

The Solution: S&B Cold Air Intakes. These are not your average filters. They are precision engineered to minimize airflow restriction while maximizing filtration efficiency.

Why It Matters:

• Lower EGTs: Better airflow helps manage Exhaust Gas Temperatures. 

• Transparent Performance: Many kits feature a clear lid, allowing you to visually inspect your filter without taking anything apart.

• Instant Gratification: You’ll notice snappier throttle response and improved fuel economy from the very first drive.

2. Goerend Converters & Transmission Pans

If you've increased your truck's horsepower and torque, your stock transmission is STRUGGLING.. All that new power is pointless if you can't actually use it. 

The Solution: Goerend Transmission components. We proudly carry Goerend Torque Converters and their high capacity cast aluminum transmission pans.

Why It Matters:

• Unmatched Strength: Goerend is the gold standard for diesel converters, built to handle massive torque loads without failure.

• Keep It Cool: Their cast aluminum pans not only add fluid capacity but also act as a heat sink, keeping your transmission fluid cooler under heavy loads.

• Longer Life: Eliminating heat and weak points is the key to making your transmission last as long as your engine.

3. Diesel Technology Of Chattanooga

For 7.3L Powerstroke owners, the Injector Driver Module (IDM) is often the root of subtle performance issues like sluggish throttle response or a rough idle. DTOC has mastered the art of IDM remanufacturing.

The Solution: Diesel Tech of Chattanooga (DTOC) Remanufactured IDMs. These are not just rebuilt  to stock specs, they are often upgraded.

Why It Matters:

• Snappy Response: DTOC offers High-Voltage/High-Current options that fire your injectors faster and harder.

• Smoother Operation: A healthy, upgraded IDM can drastically improve idle quality and make your vintage truck feel ten years younger.

4. PHP Hydra Chip (7.3L)

If you own a 7.3L and are still running a stock tune (or worse, a generic one size fits all tune), you are missing out on your truck's potential.

The Solution: The PHP Hydra Chip. This is, without question, the most powerful and flexible tuning solution available for the 7.3L platform.

Why It Matters:

• Easy Switching Capabilities: Change tunes instantly with a simple digital switch. Need to go from daily mode to tow mode at a red light? No problem.

• The Calibration Library: Get access to the massive Power Hungry Performance (PHP) library of professional calibrations, ensuring you have the perfect tune for your specific modifications.

5. Hot Shot’s Secret

The fuel and oil systems in a diesel engine are under extreme pressure, which leads to stiction in injectors and performance robbing deposits. Many additives claim to help, but Hot Shot’s Secret is backed by actual science.

The Solution: Hot Shot’s Secret oil and fuel additives, including the legendary Stiction Eliminator and Diesel Extreme.

Why It Matters:

• Restored Performance: Stiction Eliminator can fix up to 50% of injector issues in 7.3L and 6.0L engines without a single tool.

• Increased Efficiency: Cleaner fuel systems and lubricated oil systems mean better MPG and a smoother-running rig.

6. Total Seal Piston Rings

If you are building an engine for serious performance or heavy hauling, don't just put stock piston rings back in. They are a weak point that costs you power.

The Solution: Total Seal Piston Rings. These are performance engineered rings designed for maximum cylinder sealing.

Why It Matters:

• More Horsepower: Their gapless and gas-ported designs virtually eliminate blow-by, ensuring all the energy from combustion is turned into crankshaft rotation.

• Engine Longevity: By keeping combustion gases out of the crankcase, you also keep your engine oil cleaner and maximize the life of your internal components.
