Ford F-450 Parts & Accessories

The Ford F-450 Super Duty is Ford's Class 4 commercial cab-chassis truck, introduced with the Super Duty lineup in 1999 and designed for flatbed, service body, and dump body upfitting applications requiring more payload than the F-350 can provide. Built on the same Super Duty platform as the F-350 but with upgraded rear axle, frame, and suspension to achieve a GVWR in the 14,000 to 16,500 pound range, the F-450 is a popular base vehicle for utility trucks, landscaping rigs, and equipment haulers. Powered by the same 6.7 Power Stroke diesel and 6.2 and 7.3 liter gasoline V8 options as the F-350 Super Duty, the F-450 benefits from the entire Super Duty powertrain aftermarket.

Popular Upgrades

The most popular F-450 parts include Banks Power and BD Diesel intake and exhaust systems for the 6.7 Power Stroke, ARP head stud kits and EGR delete solutions for 6.0 Power Stroke F-450s, and K&N cold-air intake kits and Flowmaster exhaust for the 6.2 liter gasoline V8. Dana 80 rear axle rebuild kits including ring-and-pinion sets and carrier bearings address the heavy-duty rear axle used on the F-450 in place of the F-350's Sterling rear end. National Spring and Deaver rear leaf spring packs restore proper ride height and payload capacity on high-mileage F-450 service body and flatbed trucks.

Performance and Handling

The F-450 uses the same Dana 60 solid front axle as the F-350 Super Duty, with its rear Dana 80 axle providing higher GVWR capability for the upfit market. Bilstein 5100 series shock absorbers and add-a-leaf spring kits from Deaver improve the ride quality and load stability of F-450 flatbed and service body configurations under partial load conditions that would allow the stiffer factory springs to bounce. The 6.7 Power Stroke diesel fitted to 2011 and later F-450s responds to a turbo-back exhaust upgrade and an SCT or Bully Dog tune for 100-plus horsepower gains that improve loaded acceleration significantly on work truck applications.

What is the GVWR of the Ford F-450?

The F-450 Super Duty carries a GVWR ranging from approximately 14,000 to 16,500 pounds depending on model year and configuration, placing it solidly in the Class 4 commercial vehicle range above the F-350's GVWR ceiling. This elevated rating allows bodybuilders to install flatbed, dump, and service bodies that would exceed the F-350's maximum weight limit while maintaining the familiar Super Duty cab and powertrain. The F-450's elevated GVWR also enables higher conventional and fifth-wheel towing ratings than the F-350 when properly configured with a weight-distributing hitch or fifth-wheel setup.

Does the F-450 share parts with the F-350 Super Duty?

The F-450 and F-350 share the same cab, engine family, front Dana 60 axle, and most drivetrain components, making the extensive F-350 Super Duty aftermarket catalog applicable to most F-450 powertrain and front axle requirements. The F-450 uses a Dana 80 rear axle instead of the F-350's Sterling 10.25, and rear leaf spring packs are rated for the higher GVWR, making rear suspension and axle parts F-450-specific. Front suspension and engine components cross-reference freely between the two models within the same model year.

Why These Parts Fit Right

All parts in this collection are confirmed for the F-450's Class 4 GVWR specifications, with Dana 80 rear axle and elevated spring rate notes distinguishing F-450-specific components from the lighter F-350 specifications. Engine family notes cover 6.7 Power Stroke, 6.0 Power Stroke, and 6.2 gasoline V8 applications. Fast domestic shipping minimizes downtime on your F-450 work truck fleet.
