GMC F370 Parts & Accessories

The GMC F370 is a medium-duty conventional cab truck from the mid-twentieth century commercial truck lineup, used in vocational applications requiring a robust cab-over-adjacent chassis platform rated for substantial payload and commercial work duty. These trucks were built for fleet and commercial operators who needed dependable work platforms beyond the capacity of the light-duty pickup lineup, and they represent the industrial truck-building heritage that GMC maintained alongside its passenger and light-duty vehicle production for decades. Parts for the F370 and similar vintage GMC commercial trucks are sourced through specialty classic commercial truck parts suppliers, heavy-duty truck restoration vendors, and the network of vintage truck enthusiasts who have preserved original and rebuilt components for these rare platforms. Mechanical systems including engines, transmissions, and axle hardware can sometimes be cross-referenced with other period GM commercial truck platforms to expand the available parts pool.

Popular Upgrades

Carburetor rebuilds or replacement units for the period-correct inline-six and V8 engines used in these trucks are available through vintage carburetor rebuilders and Holley or Edelbrock aftermarket units that fit the same flange dimensions. Ignition system upgrades using modern electronic ignition modules from Pertronix eliminate the points-and-condenser maintenance that requires attention every few thousand miles on a vintage commercial truck used in regular service. Brake system rebuilds using available wheel cylinder kits, master cylinder units, and brake shoe sets sourced through heavy-duty truck restoration suppliers bring hydraulic brake performance back to safe operating standards on a truck that may have sat out of service for an extended period.

Performance and Handling

The F370 platform's commercial-grade front and rear axle and leaf spring suspension provides durable load-carrying capability that responds to fresh spring packs, rebuilt shackles, and replacement bushings that restore the factory ride quality and load floor height after decades of service. Steering system rebuilds using fresh tie rod ends, drag link components, and a reconditioned steering box address the play and imprecision that accumulates in high-mileage commercial truck steering linkage. Power steering conversion kits for similar era commercial platforms are sometimes adaptable to the F370, significantly reducing driver fatigue on a heavy truck that was often ordered with manual steering from the factory.

What engines were used in the GMC F370?

The GMC F370 used commercial-grade inline-six and V8 gasoline engines appropriate for the platform's medium-duty payload rating, with the specific engine options reflecting the commercial truck engineering available during the truck's production era. These are carbureted gasoline engines supported by the vintage truck parts community through rebuilt carburetor units, ignition components, and basic maintenance items that remain available through specialty suppliers. Identifying the specific engine displacement and model year is essential for sourcing the correct carburetor, ignition, and cooling system components from the appropriate vintage or reproduction parts channel.

Where can parts for rare vintage GMC commercial trucks like the F370 be found?

Parts for the F370 and similar rare vintage GMC commercial trucks are primarily found through specialty vintage commercial truck parts suppliers, online marketplaces connecting vintage truck enthusiasts, and the inventory of dealers who focus on pre-1970 commercial truck restoration. Many mechanical components including bearings, seals, and brake hardware can be cross-referenced to other period GM platforms that were produced in higher numbers, significantly expanding the available parts pool. Documenting the truck's engine code, axle code, and production date before searching for parts is the most important step in locating the correct components from the specialty suppliers who carry this material.
