Ford F-550 Super Duty Parts & Accessories

The Ford F-550 Super Duty designation identifies the Class 5 cab-and-chassis configuration in Ford's Super Duty lineup, available in regular cab, SuperCab, and Crew Cab configurations and designed as the foundation for the heaviest commercial upfit bodies that Ford's light-commercial cab-chassis platform can support. Used for heavy-duty dump trucks, large service utility bodies, wrecker and towing operations, and specialized equipment mounts that would exceed the F-450's GVWR ceiling, the F-550 Super Duty is the bridge between Ford's light commercial Super Duty trucks and the true medium-duty F-650 and F-750 cab-over-style trucks. This collection covers the complete powertrain and chassis requirements for the F-550 Super Duty across all Power Stroke diesel and gasoline V8 engine generations.

Popular Upgrades

The highest-demand F-550 Super Duty parts include Sinister Diesel and ARP complete head stud and gasket kits for the 6.0 Power Stroke, Banks Power diesel upgrade systems for the 6.7 Power Stroke, and MBRP and Flo-Pro three-inch turbo-back exhaust systems for maximum Power Stroke diesel performance. K&N cold-air intake kits and Flowmaster cat-back exhaust for the 6.2 liter gasoline V8 improve fuel economy on F-550 models used in applications where the diesel premium is not justified. Dana 80 ring-and-pinion gear sets and Timken carrier bearing kits address the rear axle wear in high-cycle commercial applications.

Performance and Handling

The F-550 Super Duty's Class 5 frame uses heavier rail dimensions than the F-450, and rear leaf spring selections must be rated for the F-550's elevated GVWR rather than the lighter F-450 specification. The 6.7 Power Stroke in its 2011 to present generation fitted to most current F-550 Super Duty trucks delivers 475 to 500 horsepower in stock form and responds to a turbo-back exhaust and custom tune for power figures that dramatically improve performance under the heavy loads typical of dump and service body duty. Bilstein 5100 or 5160 shock absorbers in front and rear positions improve the ride quality of lightly loaded F-550 frames over the factory shocks, which are tuned for full payload operation.

What differentiates the F-550 Super Duty from the F-450 Super Duty?

The F-550 Super Duty carries a higher GVWR of approximately 19,500 pounds compared to the F-450's maximum of approximately 16,500 pounds, achieved through a heavier frame, higher-rated rear axle, and stronger rear spring pack. Both the F-450 and F-550 use the same Super Duty cab, Dana 60 front axle, and engine family, meaning all powertrain and front suspension parts cross-reference between the two models. Buyers choosing between an F-450 and F-550 for a specific body application should verify that the body weight, payload, and body-mounted equipment do not exceed the F-450's GVWR before selecting the lighter chassis.

What engine comes standard in the Ford F-550 Super Duty?

Current production F-550 Super Duty trucks use the 6.7 liter Power Stroke diesel as the primary engine option, with the 7.3 liter V8 Godzilla gasoline engine available as an alternative for operators who prefer gasoline power. Earlier F-550 Super Duty trucks from 2003 to 2007 used the 6.0 Power Stroke diesel, and 1999 to 2003 models used the 7.3 Power Stroke, both of which have mature and well-developed aftermarket support from Banks Power, Sinister Diesel, and BD Diesel. Each Power Stroke generation requires distinct maintenance procedures and specific replacement parts for injection, cooling, and fuel system service.
