Ford F4 Parts & Accessories

The Ford F4 was the medium-duty one-and-a-half-ton truck in the original 1948 to 1952 F-series lineup, positioned above the one-ton F3 and below the heavier F5 and F6 conventional trucks in Ford's commercial hierarchy. Built on a longer wheelbase with a heavier frame and larger axles than the F3, the F4 served agricultural, construction, and commercial hauling applications requiring a payload capacity beyond what the conventional pickup body F-series could provide. Powered by the same flathead V8 and inline-six engines as the lighter F-series trucks, the F4 uses these engines in a more demanding commercial application that benefits from diligent maintenance and preventive service.

Popular Upgrades

Parts for the F4 draw from the same flathead V8 catalog used across the entire 1948 to 1952 F-series: Holley 94 carburetor rebuild kits, Gates timing chain sets, Airtex water pumps, and Carter mechanical fuel pumps. Pertronix electronic ignition conversions for the 6-volt Ford distributor improve long-term reliability on these high-mileage commercial engines. Heavier-duty front axle and steering components specific to the F4's medium-duty frame and front axle specification address wear from decades of commercial service, and one-and-a-half-ton rated rear leaf spring packs from National Spring restore correct payload capability.

Performance and Handling

The F4's medium-duty chassis uses commercial-grade front and rear axles that differ from the lighter F1 through F3 pickup-class components, and replacement suspension and drivetrain parts must be rated for the F4's payload class to maintain structural integrity. The flathead V8 in the F4 responds to the same dual carburetor and ignition upgrades applicable to the lighter F-series trucks, with dual Holley 94 carburetors on an Offenhauser manifold providing meaningful performance gains from the conservative factory tune. Converting the original 6-volt system to 12 volts using Pertronix components improves starting reliability in the F4's commercial service environment.

What is the Ford F4?

The Ford F4 was the first step into medium-duty commercial truck territory in Ford's 1948 to 1952 F-series lineup, using the same flathead V8 power as the lighter pickup trucks but with a longer wheelbase and heavier chassis specifically designed for medium payload commercial applications. It was succeeded by the F-400 and eventually the F-600 series as Ford restructured its commercial truck naming conventions after 1952. The F4 is a relatively rare collector truck today given its low production numbers compared to the much higher-volume F1 half-ton.

Do F4 engine parts interchange with F1 and F3?

All flathead V8 and inline-six engine and drivetrain parts cross-reference freely between the F1, F2, F3, and F4 since all four models used identical powertrains within each model year. Chassis, suspension, and axle components are specific to each payload class and do not interchange between the lighter pickup-class models and the medium-duty F4. Cab and body stampings may differ between the cab-and-chassis F4 and the pickup-body F1 through F3, requiring F4-specific body parts for cab restoration work.

Why These Parts Fit Right

All parts in this collection are confirmed for the 1948 to 1952 Ford F4 platform, with engine components cross-referenced to the flathead V8 and inline-six and suspension components rated for the F4's medium-duty payload specification. Electrical notes cover 6-volt compatibility for ignition and charging system components. Fast domestic shipping keeps your F4 restoration project on schedule.
