Dodge WM300 Pickup Parts & Accessories

Dodge WM300 Pickup Parts & Accessories

The Dodge WM300 Pickup is the military-specification one-ton four-wheel-drive truck produced by Dodge from 1958 through 1968, built to meet U.S. Army procurement standards and later sold in civilian form as one of the most durable and capable trucks of the era. Collectors and builders who seek WM300 Pickup parts include military vehicle restorers chasing period-correct specifications, off-road enthusiasts who value the platform's solid Dana axle setup, and vintage truck fans preserving one of the most direct ancestors of the modern Power Wagon. The WM300 platform used military-spec front and rear Dana axles, a low-range transfer case, and an open-cab or canvas-top design built to withstand hard field use, making it a durable platform for both restoration and heavy-duty off-road builds. A known OEM weakness on surviving examples is deteriorated canvas top hardware, cracked differential seals, and worn front axle U-joints that benefit from Spicer or Moog heavy-duty replacements.

Popular Upgrades

Popular parts for the Dodge WM300 Pickup include Spicer 1310-series heavy-duty U-joints for the front and rear driveshafts, Moog front steering rebuild kits, Warn hub conversion kits for the front axle, Edelbrock four-barrel carburetor upgrades for the 251 flathead six or 318 LA V8 engine options, stainless steel brake line kits from Russell, and replacement leaf spring packs from Deaver or National Spring. ARB differential lockers are a popular upgrade for the front and rear Dana axles on examples used for off-road trail driving.

Performance and Handling

The WM300 chassis responds well to front axle U-joint replacements and front end rebuild kits that restore the original steering precision lost to decades of hard use and off-road exposure. Replacing the factory leaf springs with heavy-duty packs from a reputable manufacturer restores proper ride height and load capacity, and a Bilstein shock upgrade front and rear dramatically improves on-road handling and trail capability. Buyers planning to use the WM300 for trail driving should note that the factory front axle hubs are locking units that can be rebuilt or converted to modern Warn manual hubs for improved reliability.

What engine options are available in the Dodge WM300 Pickup?

The Dodge WM300 Pickup was available with the 251 cubic inch flathead straight-six and later with the 318 LA V8 in civilian-specification examples produced during the mid-to-late 1960s. The flathead six in the WM300 is rebuilable using Carter carburetor rebuild kits, Sealed Power engine rebuild sets, and Clevite engine bearings available from Mopar restoration suppliers. Buyers upgrading to the 318 LA V8 swap should confirm motor mount compatibility and verify the correct year-range engine casting before ordering intake or exhaust components.

Are replacement parts still available for the Dodge WM300 military pickup?

Yes, a range of replacement parts for the Dodge WM300 are still available through military vehicle restoration suppliers, Mopar parts specialists, and universal drivetrain part manufacturers. Spicer U-joints, Moog front end kits, Warn hub components, and Deaver leaf spring packs are all compatible with the WM300's standard Dodge heavy-duty axle specifications. Buyers should confirm the specific axle codes, spline counts, and U-joint series before ordering drivetrain components to ensure correct fitment for their model year.
