Understanding the 2019 ford super duty f 59 stripped chassis Architecture
The F-59 is a “stripped” chassis, meaning it arrives from the factory as a frame, engine, and drivetrain without a cab or body. This allows coachbuilders and commercial body manufacturers to install custom shells, such as the popular Morgan Olson or Grumman Olson bodies. The 2019 model is particularly notable because it features the 6.8L Triton V10 engine paired with the TorqShift 6-speed automatic transmission.
The frame itself is constructed from high-strength low-alloy steel, designed to handle Gross Vehicle Weight Ratings (GVWR) ranging from 16,000 to 22,000 pounds. This heavy-duty construction means that every component, from the leaf springs to the wheel bearings, is sized for extreme duty cycles. Understanding these weight limits is critical for both safety and performance.
Unlike standard pickup trucks, the F-59 utilizes a front I-beam axle and a rear solid axle with leaf springs. This setup is incredibly durable but can lead to a harsh ride if not properly tuned. Many owners choose to add aftermarket stabilizers to help manage the high center of gravity found in tall delivery vans and motorhomes.
The 6.8L V10 Powertrain
The heart of this chassis is the 3-valve SOHC V10 engine. In 2019, this engine produced approximately 320 horsepower and 460 lb-ft of torque. While it is a thirsty engine, it is renowned for its longevity and ability to pull heavy loads up steep grades without overheating.
One of the most important things to monitor on this engine is the spark plug torque and the ignition coils. While Ford resolved the “blown spark plug” issues of the early 2000s, the 3-valve engines can sometimes experience stuck plugs if they are left in the head for too long. Regular inspections are key.
The TorqShift 6-Speed Transmission
The 6R140 transmission is a beast. It features a heavy-duty torque converter and a Tow/Haul mode that provides engine braking during descents. This is a lifesaver for those driving through mountainous terrain with a fully loaded 2019 ford super duty f 59 stripped chassis.
The transmission fluid should be clear and reddish. If it smells burnt or looks dark brown, it’s time for a flush and a filter change. Keeping this fluid cool is the best way to prevent a multi-thousand-dollar rebuild down the road.
Maintaining Your 2019 ford super duty f 59 stripped chassis for Peak Performance
Regular maintenance is the difference between a vehicle that lasts 300,000 miles and one that ends up in the scrap yard early. Because these vehicles often sit for long periods (in the case of RVs) or endure stop-and-go stress (in the case of delivery vans), the maintenance schedule must be tailored to the use case.
Oil changes should occur every 5,000 to 7,500 miles, but if you are idling frequently, you should follow the “Severe Duty” schedule. Use a high-quality 5W-20 synthetic blend oil and a Motorcraft FL-820S filter to ensure proper flow and filtration.
Don’t forget the chassis grease points. The F-59 has several grease zerks on the front suspension and steering linkage. Pumping fresh grease into these joints every time you change the oil will prevent premature wear on the kingpins and tie-rod ends.
Braking System and Hydroboost
The F-59 does not use a traditional vacuum booster for the brakes. Instead, it uses a Hydroboost system, which utilizes pressure from the power steering pump to provide braking assist. This is common in heavy-duty applications where engine vacuum is insufficient.
Check your power steering fluid regularly, as a leak in this system can affect both your steering and your ability to stop. If you hear a whining noise when turning the wheel or pressing the brake pedal, you may have air in the system or a failing pump.
Cooling System Integrity
The cooling system on the 2019 ford super duty f 59 stripped chassis is massive, but it has to be to keep that V10 cool. The radiator is prone to collecting debris, especially in delivery environments. Use a garden hose to gently wash out the fins from the back side to maintain airflow.
Always use the specific Orange OAT coolant (or the newer Yellow P-OAT if updated by Ford) recommended for this model year. Mixing coolant types can lead to “sludging,” which will clog the heater core and the radiator, leading to expensive repairs.
Common Issues and DIY Troubleshooting
Even a well-built machine like the F-59 has its quirks. One of the most common complaints involves the exhaust manifold studs. Over time, the heat cycles of the V10 engine can cause the rear studs to snap, leading to a “ticking” sound when the engine is cold.
If you hear this tick, address it sooner rather than later. A small leak can eventually erode the cylinder head surface, turning a simple stud replacement into a cylinder head pull. Using stainless steel replacement studs is a popular “pro” tip to prevent the issue from returning.
Another area to watch is the fuel pump. On the stripped chassis, the fuel tank is often located mid-ship or at the rear. If the vehicle sits with a low fuel level, the pump can overheat. Always try to keep at least a quarter tank of fuel to keep the pump submerged and cool.
Suspension “Wander” and Handling Fixes
Many owners of the 2019 ford super duty f 59 stripped chassis complain about “sawing” at the steering wheel to stay in a lane. This is often caused by the factory steering stabilizer being undersized for the weight of the completed body. Upgrading to a heavy-duty stabilizer can make a world of difference.
Additionally, check your tire pressures. Because these vehicles are built on a stripped frame, the final weight can vary wildly. You should weigh your vehicle at a CAT scale and adjust your tire pressure based on the tire manufacturer’s load inflation table, rather than just following the door sticker.
Electrical and Battery Care
RVs and delivery vans often have complex electrical needs. The F-59 usually comes with a high-output alternator, but the batteries are still a weak point if the vehicle sits. If you are a weekend warrior, consider installing a battery disconnect switch or a smart trickle charger.
Corrosion on the battery terminals is a common cause of “no-start” conditions. Clean the terminals with a wire brush and apply a protective spray. Also, inspect the ground straps connecting the engine to the frame, as these can rust and cause mysterious electrical gremlins.
Upgrading Your F-59 for Comfort and Capability
If you find the ride of your 2019 ford super duty f 59 stripped chassis too harsh, there are several upgrades that can help. The stock shock absorbers are designed for durability, not necessarily comfort. Replacing them with Koni FSD or Bilstein 4600 shocks can significantly reduce the jarring felt over bridge expansions and potholes.
For those dealing with heavy rear-end sag, adding helper springs or air bags can level the vehicle. This not only looks better but also improves the steering geometry by keeping more weight on the front tires. A level chassis is a safer chassis.
Finally, consider a custom engine tune. While the V10 is powerful, the factory shift points are often optimized for fuel economy rather than driveability. A 5-Star Tuning or similar module can recalibrate the transmission to hold gears longer on hills, preventing the constant hunting between 5th and 6th gear.
Essential Tools for the F-59 DIYer
Working on a chassis this large requires more than just a basic socket set. You will need heavy-duty tools to handle the high torque specs. Here is a short list of must-haves:
- 3/4-inch drive socket set: For large suspension bolts and lug nuts.
- Heavy-duty torque wrench: Capable of at least 150-250 lb-ft.
- OBD-II Scanner: To read Ford-specific codes (FORScan is highly recommended).
- 20-ton bottle jack: For safe lifting of the heavy frame.
- Creepers: Because you will be spending a lot of time under the chassis!
Safety First: Working Under a Heavy Chassis
We cannot stress this enough: safety is paramount when working on a 2019 ford super duty f 59 stripped chassis. This vehicle weighs several tons, and a failure of your lifting equipment can be fatal. Always use jack stands rated for the weight of your vehicle.
Never rely on a hydraulic jack alone. When working on the steering or brakes, ensure the wheels are chocked. Because these vehicles often have air brakes or complex parking brake mechanisms, they can roll unexpectedly if the system is depressurized.
If you are uncomfortable with the scale of these repairs, do not hesitate to take the vehicle to a dedicated Ford Commercial Service Center. They have the heavy-duty lifts and specialized tools required to service the F-59 safely and efficiently.
Frequently Asked Questions About 2019 ford super duty f 59 stripped chassis
What is the oil capacity of the 2019 F-59 V10 engine?
The 6.8L V10 engine typically takes 7 quarts of 5W-20 oil. However, always check the dipstick after filling, as oil cooler configurations can slightly alter the total capacity required for a full reading.
Can I use E85 fuel in my F-59 chassis?
Most 2019 F-59 models are not Flex-Fuel compatible. You should use regular unleaded gasoline with an octane rating of 87 or higher. Using E85 in a non-compatible engine can damage the fuel injectors and seals over time.
How often should I change the transmission fluid?
For normal driving, Ford suggests a long interval, but for commercial or RV use, many experts recommend changing the fluid and filter every 30,000 to 45,000 miles. This ensures the 6R140 transmission remains reliable under heavy loads.
What are the common signs of a failing steering stabilizer?
If you experience “death wobble” (violent shaking of the steering wheel after hitting a bump) or if the vehicle feels excessively “darty” on the highway, your stabilizer is likely worn out. It is a simple bolt-on replacement that yields immediate results.
